2018, March 19 - The publisher Elsevier has provided our CAMS community a free link to our new article called 'A Survey of Southern Hemisphere Meteor Showers' until May 7, 2018. It includes the CAMS Shower LookUp Table (ShowerLookUpTable.txt - near bottom of page), a new tool used in the CAMS near-real time display for assigning new CAMS orbits to previously identified meteor showers.
2018, April 1 - Re-Entry Alert: the Chinese space station Tiangong-1 (about the size of a school bus) is about to have an uncontrolled re-entry somewhere on Earth on or around Sunday April 1. Because the station is no longer controlled, the exact time (and thus the place) of the breakup is uncertain. For the latest predictions, see this Aerospace Corporation website.
2018, March 27 - Data reduction for 2017 has been completed and results have been added here. The CAMS network as a whole continued to grow in yield and captured about 135,000 meteoroid orbits. California: 53,000; BeNeLux: 35,000; New Zealand: 5,900; LOCAMS: 26,000; UAE: 9,800; Florida: 5,000; Mid-Atlantic: 373; SA: 259. CAMS California improved its hardware. CAMS BeNeLux grew significantly larger. Further growth is expected in the coming year from LOCAMS and CAMS Florida.
2018, March 25 - Marcelo de Cicco reports that the EXOSS network has its first pair of CAMS cameras online. The cameras are operated by Eduardo P. Santiago, who is the CAMS point of contact for camera installations, and Dr. Irapuan Rodrigues of UNIVAP. The top photo shows the installation at UNIVAP, with Santiago (right) and Rodrigues (left), while the bottom photo shows one of three meteors captured last night.

2018, March 11 - Carl Johannink reports that CAMS BeNeLux held its annual meeting today at the public Bussloo Observatory in the Netherlands. To celebrate the 100000th orbit, Koen Miskotte made some of his famous cakes. Also shown is an impression of the day with a presentation by Jean-Marie Biets.
2018, February 22 - Dave Samuels reports that new scripts have been developed that are better at transmitting CAMS data from stations at locations with poor internet connectivity. The scripts have been tested at Fremont Peak Observatory and data are now received in good order each day, and are posted here.
2018, February 18 - The UAE Astronomical Camera Network (UACN) was in the news today, when it was announced that the UAE Space Agency will work with the International Astronomical Center to monitor the fall of China's Tiangong-1 Space Laboratory. The re-entry is expected to happen in late April somewhere between 43S and 43N, an area that includes the location of the UACN.
2018, February 16 - Both California and BeNeLux skies were clear tonight, with both network recording more meteors than in all previous years together. California weather in February has been good for meteor observations, but could mean another drought year is ahead.
2018, February 9 - Dave Samuels reports the sighting of a slow-moving bright meteor from Brentwood, CA, at 3:17:40 UT today. The meteor was captured by the SkySentinel allsky camera at Redding.
2018, January 31 - The near-perigee blue Moon lunar eclipse tonight, as seen from station CAMS Sunnyvale, was captured in this compilation of all-sky images by Jim Albers.
2018, January 20 - A bright meteor was seen over the central valley in the CAMS survey area at around 02:08 UT this evening (AMS 257-2018).
2018, January 3 - Robert Haas has created this video on Google Drive (in Dutch) to explain the advantages of using the autonomous CAMS 2 software.
2018, January 1 - HAPPY NEW YEAR! The figure below is the first daily map of meteor shower activity in 2018.
2017, December 14 - The Geminids did not disappoint last night. Many were bright, but the meteor that stole the show in the SF Bay Area appeared at 07:58 UT. Observing from Fremont Peak Observatory under a clear sky with some thin cirrus clouds, Peter Jenniskens described the meteor as "an intensely bright green point of light with halo, leaving a brief persistent train". The meteor was recorded in the CAMS network and also documented by an all-sky camera operated by Wes Jones in Belmont and a Desert Fireball Network camera operated by Jim Albers in Sunnyvale (photo above). The bright Geminid moved from San Leandro (37.74N, 122.17W at 106 km altitude) to San Francisco (37.75N, 122.43W at 62 km altitude), penetrating to about 40 km altitude. If material survived, it fell in the Pacific Ocean West of San Francisco.
Compilation of Geminids seen at the Sunnyvale CAMS station by Jim Albers from the night of December 13/14.
2017, December 13 - Clear weather during the Geminids in California, Arizona and the United Arab Emirates has resulted in shattering all previous records on the number of meteors detected in a single night. Last night had 3003 Geminids recorded, as well as 1154 sporadic meteors. Tonight's peak night promises an even higher tally. Well done!
2017, December 10 - Those interested in seeing this year's Geminids should come to California. Weather forecast is good and the Moon is out of the picture. Last night, CAMS already detected significant Geminid activity (green blob in picture above, showing data from December 9/10), as well as meteors from the sigma Hydrids (orange). Follow Geminid activity here.
2017, November 24 - Jim Richardson reports that there is now a new Current Visual Meteor Activity website, a site that displays the visually observed meteors in the IMO Visual Meteor Database in near-real time. The site will be updated about once a week.
2017, November 22 - The five computers at Fremont Peak Observatory were replaced by a single PC over the weekend, in an ongoing effort to automate the CAMS data reduction pipeline. After several cloudy nights, last night was clear and the first set of observations was transmitted and posted autonomously on the CAMS near-real time reporting site this afternoon. Three meteors were identified as alpha Monocerotids, from an unknown potentially hazardous long-period comet.
2017, November 19 - Many bright Leonids were detected in the CAMS network on November 19. The picture above is by Klaas Jobse. [More here]
2017, November 15 - Nick Moskovitz reports that a bright fireball was detected by the LO-CAMS network just north of Phoenix at 03:26 UTC on November 15. The American Meteor Society received over 1320 fireball reports from about 4 different events that occurred over the US, France, and Germany within ten hours. Two events were linked to the Taurid meteor shower, but initial data reduction of the CAMS trajectories shows that the Arizona fireball had a radiant near the pole. The initial entry speed was a high 26 km/s. No radar signature from falling stones was detected, but some meteorites may have fallen in the White Mountains. [More here]
Re-entry of a Progress rocket body (UACN3 data).
2017, October 14 - Mohammad Odeh reports that the United Arab Emirates Astronomical Camera Network (UACN) is back online, in part thanks to a generous donation from the ISP provider Etisalat. Two of the three stations are back in operation. During the third night in action, both stations UACN1 and UACN3 captured the widely reported 2017-056B Progress rocket body re-entry over the Arab Peninsula at 19:29:34 local time (UTC +4h) on October 16. The network also made a nice detection of the compact October Ursae Majorids shower that night. Nightly reports of meteor shower activity from the UACN are here. Because of its location, UACN results are available shortly afer 8 UTC, the first data of last nights meteor shower radiants to be reported each day.
2017, October 14 - A nice return of the October Ursae Marjorids (shower 333) was observed by the UANC, LOCAMS and California networks October 14-16. Go here and select dates around 2017-10-15.
2017, October 6 - A predicted outburst of October Camelopardalids was detected by the CAMS BeNeLux network.
2017, October 3 - Paul Roggemans reports that the CAMS BeNeLux network has grown to 88 operational cameras. At Grapfontaine, two Watec cameras were installed at the Observatoire Centre Ardennes . The cameras cover the same area over Belgium that is covered by the BRAMS radio-MS project by BIRA. A number of other stations were expanded, including Ermelo, where Koen Miskote added 2 cameras for a total of four, aimed at a common survey area to the north. At Ooltgenplaat, Piet Neels added four cameras for a total of eight. At nearby Oostkapelle, Klaas Jobse also expanded to eight cameras. In Mechelen, Luc Gobin added two cameras and Paul Roggemans added one camera so that 10 cameras are now operating at this site. In Terschelling, in the northern part of the Netherlands, Piet Neels and Robert Haas added 4 new cameras. In Texel, Robert Haas added 3 new cameras. And in Zoersel, Bart Dessoy expanded to 5 cameras. The new stations are run by a new version of AutoCAMS developed by Steve Rau.
2017, September 28 - Peter Jenniskens added a new capability to the CAMS data sphere that enables a comparisson with data collected in previous years for that date. Click on "Past Data" and a new window tab will appear, click on the tabs at the top of the browser window to flip from present to past data and back to spot meteor outbursts.
2017, September 21 - Marcelo de Cicco presented the FDL effort in a talk at the International Meteor Conference in Petnica, Serbia. Pete Gural spoke about the new improvements to the trajectory solver code.
2017, September 8 - A new web portal for CAMS data visualization has come online. It is now possible to see last night's meteor detections by the LOCAMS and Florida networks and the most recently reduced data from the BeNeLux network by Martin Breukers and Carl Johannink. Just go to http://cams.seti.org/FDL/ and choose the date from the "Pick a date" window. Data from the other CAMS networks will gradually come online in the coming months.
This new web tool is part of an effort by Frontier Development Lab 2017, a NASA research accelerator program at the SETI Institute, led by James Parr and Bill Diamond and supported by NVidia and IBM amongst others, that set out to use artificial intelligence techniques to automate the CAMS data reduction pipeline.
Over the summer, CAMS software tools have been updated by Pete Gural to run in batch mode. Python scripts designed by Jack Collison, Peter Jenniskens, and Siddha Ganju collect the submitted files, run the CAMS software, and compare the calculated orbit with a meteor shower template file based on showers assigned by Jenniskens. The new web tool designed by Jenniskens, Ganju and Leo Silverberg displays each shower radiant in sun-centered ecliptic coordinates, with a color assigned proportional to the entry speed. By hovering the cursor over a colored meteor radiant, one can see the IAU shower number. Clicking brings up a new window that shows the 2010-2016 CAMS data for that shower displayed in the planetarium program by Ian Webster. That makes the new web tool a portal to the minor showers in Webster's visualization program.
At the moment, the reduction of CAMS data from California and New Zealand is still very slow due to numerous false detections (clouds, birds, planes...). During the summer, Susana Zoghbi, Antonio Ordonez, Marcelo de Cicco, and Pete Gural developed machine learning and deep-learning tools to discriminate meteors from other detections. Gural will use this to improve future versions of the Confirmation and Coincidence programs. Further improvements are expected now Jim Albers, Dave Samuels, Steve Rau and Peter Jenniskens are upgrading the hardware and software environment at the existing CAMS networks.
Finally, Andres Plata Stapper used deep-learning tools to discover additional structure in the 2010-2016 shower data pre-assigned by Jenniskens, which in the near future is expected to improve and enrich the meteor shower assignment template. Also, David Holman is working to created a new stream finder tool to help improve the shower isolation from the sporadic background.
The CAMS data reduction automation will make it possible to expand and create new low-light video camera networks to facilitate a continuous global monitoring of night-time meteor shower activity. [More here]
2017, August 13 - Carl Johannink and Martin Breukers of CAMS BeNeLux report that some 1070 meteors were captured during the peak of the Perseid meteor shower, with the results from some cameras still expected to come in after the observers have returned from vacation.
2017, August 8 - Peter Jenniskens finished the shower assignments, enabling Ian Webster to update the CAMS shower vizualisation tool to include all CAMS data up to the end of 2016. Many of the minor meteor showers are now well depicted.
2017, July 30 - Tim Cooper reports that the new CAMS South Africa network operated successfully. Data analysis shows that 167 meteors were captured simultaneously by the four cameras at Bredell and the four at Victory Park. Aside from many Southern delta Aquariids, there was a diffuse activity around R.A. = 20, Dec. = -15 degrees, and a compact radiant around R.A. = 40, Dec. = -32. No meteors from the Borisov trail were captured. Visual observations suggested a hint of activity later in the night. Peter Jenniskens, Mike Koop and Marcelo de Cicco observed the moon for possible impacts from California.
2017, July 29 - Peter Zimnikoval writes that the dust trail encounter with comet C/2015 D4 (Borisov) may also cause a noticeable uptick of lunar impact flashes if there are enough large meteoroids in the trail. He writes: "Of course, no one knowns if particles in the stream will reach sizes to be detected this way." If it does, the Moon happens to be in a favorable geometry to see this, with best viewing at the longitude of the central USA. The trail will hit the Moon a little later than Earth. Train your telescope at the dark side of the Moon in the area dotted in the attached graph. Update: The moon will cross the Borisov trail on July 29, 01h16m UT, 0.9 hours after the Earth, according to calculations by Pete Gural.
2017, July 29 (00:22 UT) - Earth is about to travel through the 1-revolution dust trail of long-period (700 year) comet C/2015 D4 (Borisov).
Only about once every 25 years is such an intermediate long-period comet discovered that passes close enough to Earth's orbit to have dust trail encounters. This one passed perihelion in 2014. On July 29 at 0h22m UT, we are crossing the trail just behind the comet and near the center on the inside [Read more: CBET], both favorable conditions for meteor activity. However, we do not know if the comet was active in the previous return. No annual shower is known from this comet. If meteoroids were released, the shower may be visible from South Africa, radiating from the constellation Columba near the horizon in the south east.

2017, July 23 - First light tonight for the CAMS South Africa network. 87 meteoroid orbits!! Network coordinator is Tim Cooper, former director of the Meteor Section of ASSA, who operates four Watec Wat902H cameras from Bredell, a suburb of Johannesburg. Four more cameras are operated by Oleg Toumilovich from Victoria Park, at a distance of 31 km. Setup support was provided by Steve Rau. Stations are ready for the upcoming encounter with the dust trail of comet C/2015 D4 (Borisov) on July 29.
2017, June 26 - The Frontier Development Lab has started its activities. The FDL Comet Team that will work to automate the CAMS data processing consists of (from left to right): Susana Zoghbi, Antonio Ordonez, Andres Plata Stapper, and Marcelo de Cicco. They will work on deep-learning tools to filter and process the data. In addition, Jack Collison will provide support with the data processing automation. Pete Gural (CAMS software) and Siddha Ganju (Deep Learning techniques) are the technical mentors.
