Arid radiants seen by CAMS on Sept. 29/30 2021
2021 Sept. 29 - CAMS networks in New Zealand and Chile detected a predicted outburst of meteors from comet 15P/Finlay on Spetember 27-30, the first time meteors were seen from this comet and the new shower is called the "Arids" (number 1130). The outburst was caused by Earth crossing the 1995 dust ejecta.
There is perhaps more to come. On October 6/7, Earth will cross the 2014 dust trail. The comet had two activity outbursts in 2014 and Ye et al. (2015) expect a denser trail and perhaps higher rates as a result. [More here]
2021 September 21 - Ozan Unsalan reports that the CAMS Turkey network cameras received new lenses and now show rich star fields.
2021 September 15 - Siddha Ganju reports that the three camera enclosures for CAMS India have been shipped.
2021 September 10 - Peter Jenniskens gave a talk on CAMS for the Houston Astronomical Society.
2021 August 14 - CAMS Texas and CAMS California detected an outburst of Perseids bewteen 6 and 11h UTC today. Peak rates increased to ZHR = 130 per hour above normal 40 per hour Perseid rates. The peak was at 8.2 h UTC August 14. Most meteors were faint. This encounter with the dust trails or Filament of 109P/Swift-Tuttle was not anticipated.
2021 August 13 - Carl Johannink reports that over 1000 meteors were captured by CAMS BeNeLux. The graph above shows their trajectories. Most are Perseids. Graph is courtesy of Tammo Jan Dijkema.
2021 August 9 - Peter Jenniskens reports that northern heisphere networks are detecting an outburst of kappa Cygnids. The shower is known to return every 7 years since it was first seen in 1879. The years 2020 and 2021 fit in that sequence. Carl Joannink of Cams BeNeLux reports that 2021 rates seem to be better than 2020. The shower is expected to peak around the time of Perseid maximum. The shower is known for occasional fireballs with multiple flares.
2021 August 8 - Walt Cooney reports that another station with 8 cameras was added to CAMS Texas. After completing a 4-camera station in Magnolia (Fred Cyrway), an 8-camera station was added by Joel Brewer in Sealy. Luke Juneau and Dave Samuels assisted with the hardware and software installation.
First night of observations of the expanded CAMS Texas network resulted in a total of 233 meteors, among wich were meteors from an outburst of kappa Cygnids (KCY in the plot above).
CAMS Turkey station in Yozgat
2021, August 3 - Ozan Unsalan reports that, with the help of Dave Samuels, CAMS Turkey achieved first light tonight. The network consists of 6, 5 and 5 cameras, respectively, at three locations in central Turkey. Two Perseids and one sporadic meteor were captured from Kayzeri and Yozgat. Setup continues at the third site in Akdagmaden.
2021, July 27 - Walt Cooney reports that CAMS Texas has expanded with a 4-camera station operated by Fred Cyrway. On the first night of operations, a nice fireball with three flares was captured just above Jupiter. The Moon is to the left on the edge of the frame.
2021, July 22 - Siddha Ganju reports that CAMS now has its own Wikipedia website.
2021, June 19 - CAMS observations in 2021 showed a new shower in the June Aquilid complex, now called the June theta2 Sagittariids. The shower was also seen in 2020, but not in prior years. [Read More]
2021, May 25 - The SETI Institute has created for us a crowd funding campaign to help establish a CAMS India network to patch a gap in global CAMS coverage. For this campaign, special mugs and T-shirts were designed.
[Support a CAMS India observatory]
Update: The campaign has ended. 88 people supported the project and thanks to additional donations our funding goal was reached. Thank you!
2021, May 6 - Pete Gural has modified the Coincidence program (v 2.39) to reject trajectories that are nearly completely below 25 degrees elevation, so that now the LO-CAMS and BeNeLux data from RMS cameras using the correct field of view (3.6 mm or longer focal length lenses) can be included in the CAMS data processing pipeline.
2021, Apr. 20 - A paper appeared online today in the journal ICARUS describing the long-period comet showers in CAMS data that have known shower parent bodies. It was found that most long-period comet showers are active for many days, showing precession of the comet orbit over time. Meteor showers were found for nearly all known comets approaching Earth orbit to 0.01 AU that have orbital periods in the 250 to 4,000 year range.
2021, Apr. 8 - Nick Moskovitz reports that LO-CAMS has dramatically expanded, adding Global Meteor Network (RMS) cameras to their network. The coming weeks will see RMS data included in the network results from one of the cameras at Mars Hill, after which more cameras from other stations will be added. There are 6 RMS cameras per station.
2021, Apr. 1 - After many years of manually processing the CAMS BeNeLux data, Carl Johannink and Martin Breukers now report that per April 1 the data reduction will be automated. The station operators in the CAMS BeNeLux network will still check the results, so there are few false detections going into the Coincidence triangulation process. Main issue to be solved now is how to include the Global Meteor Network cameras in the CAMS BeNeLux network, which often capture meteors low in the sky. When the station is far from the meteor track, this introduces inaccurate trajectories in the triangulation calculation.
2021, March 27 - Station Bindoon of CAMS Australia has an unusual problem as of late: insects. The video feed shows many dots of light darting around the cameras, creating numerous false detections. The firefly population will remain active for the coming weeks.
2021, March 22 - Peter Jenniskens reports in a CBET telegram that southern hemisphere CAMS networks detected an unusual shower on March 22, 2021. The shower is called the zeta Pavonids (IAU number 853). The shower activity profile had a full width at half maximum duration of only 0.46 degrees centered on 1.41 degree solar longitude. The shower was detected between 2021 March 21 19h and March 22 11h UTC. [More here].
2021, March 13 - Peter Jenniskens reports in a CBET telegram that southern hemisphere CAMS networks detected strong activity from the beta TUcanids (IAU number 108). Initially mistaken for the nearby delta Mensids (IAU 130), this shower was also strong in radar observations last year in 2020. A total of 29 beta Tucanids were triangulated by CAMS networks this year, compared to 5 meteors last year. [More here].
2021, March 1 - Eric Egland reports that he has added video ground-loop isolator baluns to the Fremont Peak Observatory station cameras. The baluns were mounted between the camera and the 75ft BNC cables and immediately removed much if not all of the video interference that had gradually built up over the years.
2021, February 12 - Peter Jenniskens reports in a CBET telegram that southern hemisphere networks in Australia (M. Towner, coordinator), Chile (S. Heathcote and E. Jehin) and New Zealand (J. Baggaley) detected a strong outburst of meteors from a radiant at R.A. = 192.6 +/- 3.3 degrees, Decl. = -56.0 +/- 1.6 degrees, with speed Vg = 55.8 +/- 1.7 km/s. The shower is called the gamma Crucids (IAU number 1047), but this may have been a return of the alpha Centaurids. That shower was strong in visual observations in 1980.
2021, Jan. 26 - The Volantids returned as expected. A follow-up CBET was issued today describing the CAMS observations. [More here].
2021, Jan. 1 - CAMS did very well in 2020, despite the ongoing Covid-19 pandemic. Just compiled the summaries from last year's CAMS data and have the following raw totals: NAMIBIA now 98581, was 18875 in 4 months in 2019, CHILE now 66556, was 51700 in 6 months last year, BeNeLux now 45586, was 42083 last year, LO-CAMS (Arizona) now 44858, was 49749 last year, cams California now 42281, was 69924 last year, CAMS Australia now 31240, was 37837 last year during 7 months, CAMS Florida now 30303, was 24944, United Arab Emeriates Astronomical Camera Network now 24003, was 16085, CAMS Arkansas now 14389, was 13630, CAMS South Africa now 13006, was 9640, CAMS Northern California now 5413, was 4582, CAMS Mid-Atlantic now 992, CAMS Texas now 960, and CAMS EXOSS (Brasil) now 399, was 342. Altogether, the CAMS networks collected about 418,000 orbits in 2020, compared to 364,000 in 2019. [ More here ].
2020, Dec. 30 - Peter Jenniskens reported in a CBET telegram that the Volantid meteor shower has returned this year. The shower is expected to peak on New Year's Eve (UT). If so, southern hemisphere observers may be greeted by the new year with a naturual fireworks display. [More here]
2020, Oct. 29 - Peter Jenniskens issued a CBET telegram describing a peculiar shower detected in 2019 CAMS data. Now named the 29 Piscids (IAU 1046), the shower was briefly detected in the period October 17-19, and then again a month later on Nov 11-18. The stream originated from a Jupiter Family comet. The shape of the orbit and its orientation are the same in the October and November apparitions, so we suspect this is the same stream. The meteoroids move in a very low inclined orbit, almost in the orbital plane of Earth.
2020, Oct. 14 - A strong outburst of a new shower, now called A-Carinids, was detected by all southern hemisphere networks. The radiant is near the ecliptic pole. Tim Cooper deteted the shower visually towards the tail of activity. A CBET was issued.
2020, Sep. 22 - An outburst was detected just above the Hyades. Now called the September upsilon Taurids (IAU shower 1045). A CBET was issued.
2020, Sep. 12 - A new network was added to the CAMS family: CAMS Texas. Operated by Walt Cooney. Thanks to support by Luke Juneau and Dave Samuels, the new network started off with four cameras, two at each location. The sites are near Houston. On September 12, 12 meteors were triangulated.
2020, Aug. 30 - After six years of hosting the CAMS New Zealand station at his private observatory in Geraldine, CAMS NZ founder and well known amateur astronomer Peter Aldous decided he had reached an age where it no longer was safe to climb the roof observatory to maintain CAMS. CAMS NZ coordinator Jack Baggaley found a new site at Mount John observatory, where Nigel Frost has taken over the technical duty of maintaining the CAMS station. The new site had a first clear night on August 30th.
2020, Aug. 21 - Starting on August 18, the CAMS networks picked up meteors that were labelled "chi Cygnids", IAU shower 797. The radiant in August was still in Aquila. This early sighting forwarned a period of activity from this shower, which hadn't been seen since 2015. Indeed, the shower manifested much as expected, peaking in mid September. A CBET was issued and a paper summarizing the 2020 return was written for the journal JIMO.
2020, Aug. 19 - In the evening of August 19, a wildfire swept past Lick Observatory. Firefighters managed to fend off the flames and all but one unused building was spared. However, flames crept up the hill and licked the power conduit of CAMS, melting the plastic cover and cable. CAMS at Lick Observatory was without power while the area remained closed off. Once the smoke cleared, Bryant Grigsby and Peter Jenniskens repaired the damage.
2020, July 27 - Martin Towner reports that CAMS Australia is back online now plugs have been replaced at Curtin University and the power supply of the PC at Bindoon was repaired. The PC was returned by Daniel Busan.
2020, July 25 - Mohammad Odeh reports maintenance of the UACN stations is completed.
2020, July 23 - Marcelo de Cicco reports that three new cameras are contributing data to the EXOSS CAMS network in Brasil. Cameras 1160 (Marco), 1260 (Suzanne) and 1270 (Michael) of the Sao Paulo node are now regularly obtaining orbits.

2020, June 19 - CAMS 2010-2016 data were added to the Meteor Shower Portal.
To quickly access those old data, type the date in the top-right "Choose a date" window like "2015.08.12" with points in Chrome, or "2015-08-12" with dashes in Safari.
2020, June 10 - CAMS New Zealand, CAMS Namibia and CAMS Chile detected each a few meteors of a new long-peroid comet shower now called the chi Phoenicids (shower 1036). The shower may be annual. The stream has an inclination of 90 degrees, moving perpendicular to the planet of the planets. Results were announced on CBET 4798.
2020, May 15 - Two new meteor showers were detected today, both caused by long-period comets. Now called the gamma Piscis Asutrinids and the sigma Phoenicids, they were added to the IAU Working List of Meteor Showers as numbers 1034 and 1035. Results were announced on a CBET.
2020, April 29 - CAMS New Zealand detected five orbits of a shower called the rho Phoenicids, visible in video data only just before sunrise in the morning. SAAMER-OS reported strong activity of this shower. Results were reported on CBET.
2020, April 27 - All CAMS networks reporting the detection of an outburst of h-Virginids caused by a Jupiter Family comet. Tim Cooper reports that the shower can be observed visually. The detection was announced on CBET.
2020, April 15 - CAMS Namibia and CAMS BeNeLux detected significant activity of a long-period comet shower, the phi Serpentids. Seven meteors were detected between solar longitudes 25.21 and 25.39 degrees (J2000). The shower is normally a weka annual shower, but in some years the rates appear to be higher than normal. Calculations by Esko Lyytinen showed that the good years allign with the motion of a dust trail, with the next good year expected in 2027. Results were reported on CBET 4756.
2020, March 30 - CAMS Australia and CAMS Chile detected the delta Pavonids of comet 1907 G1 (Grigg-Mellish), which was in outburst last year. We published a paper in Planetary Space Science determining the orbital period of the comet based on the meteor observations.
2020, March 13 - CAMS Namibia (T. Hanke, E. Fahl, and R. van Wyk) detected five meteors from the delta Mensid shower between 18h25m and 23h09m UTC on March 12. At the same time, the SAAMER-OS radar system in Argentina reported an outburst of this shower and identified a likely parent body: minor planet 2006 CS. The detection was reported on CBET 4772.
2020, March 8 - A global pandemic of COVID-19 is underway and calls for stay-at-home and social distancing. Stay safe! We expect intermittent access to the website in the coming months.
2020, January 24 - A bright comet described in a circa 553 A.D. book, "Histories of the Wars", may have been responsible for a brief and unexpected meteor shower in April 2019, so conclude researchers in a paper published this week in Planetary and Space Science. "That comet appears to be on its way back," said meteor astronomer Peter Jenniskens of the SETI Institute. "We don't know whn it will arrive back in the inner solar system, but the meteor shower can help astronomers search for it." [Full story]
2020, January 2 - The year 2019 saw a massive expansion of the CAMS camera network and those behind the scenes (especially Dave Samuels, Steve Rau and Pete Gural) worked hard to keep the network in tip-top shape. As a result, the annual tally of measured meteoroid orbits doubled this year to 360,000!
Orbits measured in 2019 (raw data):
Arkansas (13,630, up from 2,595 last year), Australia (37,837, new since June), BeNeLux (42,083, similar to last year), California (69,924, similar to last year), Chile (51,700, new since July), EXOSS (342, similar to last year), Florida (24,944, up from 5,654 last year), LO-CAMS (49,748, up from 45,230 last year), MA (not in yet), Namibia (18,875, new since September), Northern California (4,582, similar to last year), New Zealand (23,806, up from 3,201 last year), South Africa (9,640, new since June), UAE Camera Network (16,085, up from 10,583 last year).
