2017, February 9 - Dick Spalding, the father of the Sentinel all-sky camera network, has passed away. Lindley Johnson, Planetary Defense Officer at NASA wrote: "He was a great man as well as an insightful scientist and a hero to us all, albeit largely unsung. It is nice to see this latest paper come out and know that he was active to the end in uncovering the mysteries of nature. He will of course be greatly missed, but I hope he was heartened in his last days by seeing us finally making progress in getting bolide reports instituted into our warning infrastructure. In his memory, we will redouble our efforts to make full use of what he had shown us of what is possible to better understand the science of natural objects entering our atmosphere in service of better protection of all human popuations and our collective society." Mark Boslough added: "He was a pioneer and a tireless behind-the-sceness supporter of our field. One of the most creative thinkers I have ever known."
2017, January 20 - The Journal of the International Meteor Organization published our paper confirming the delta Mensids shower, based on observations from the CAMS New Zealand network.
2017, January 18 - Artist Scott Kildall had the official opening of his Strewn Fields project in a gallery in San Francisco on December 5. Now, his website is updated with images of the artwork. The project is a data-vizualization of meteorite impact data etched into stone. Working with Peter Jenniskens, Scott's artwork is inspired by the strewnfields of Almahata Sitta, Sutter's Mill, Chelyabinsk, and Saricicek.
2017, January 3 - Carl Johannink reports that a fireball appeared over Belgium in the CAMS BeNeLux survey area on January 3 at 02:10:49 UT. The meteoroid arrived on an asteroidal orbit, entered at 15.6 km/s and traveled ENE from Roeselare to Ghent in the CAMS cameras operated by Klaas Jobse, Paul Roggemans and Luc Gobin. From all-sky images, Marco Langbroek derived an end point at 30 km altitude over Antwerp. From this, Peter Jenniskens calculated a preliminary fall area just east of Antwerp near the town of Schilde.

2017, January 2 - Notice: The new year brings a new leap second. Pete Gural asks to please update your LeapSeconds.txt file by adding "2457754.5 37.0 Jan 2017".
2017, January 1 - Happy New Year from the CAMS team! Software engineer Ian Webster worked with Peter Jenniskens to create this visualization tool of CAMS data. You can display all showers that were identified in the March 2013 release, including the sporadic background! Use cursor to change viewing perspective. Above are the Quadrantids, currently active for northern hemisphere observers.
2016, December 31 - Carl Johannink reports that CAMS BeNeLux participant Jos Nijland of Benningbroek and his family are safe after a devastating fire destroyed their home and belongings in the early morning of December 31. CAMS cameras 358/359 and the European Network All-sky Station EN95 will be temporary offline. Among the lost items is the visual archive of the Dutch Meteor Society. Members will make an effort to rebuild the archive from existing copies.
2016, December 22 - Peter Gural updated the MeteorAutoCal software to process monthly batches. The new tool greatly eased the data reduction effort for CAMS New Zealand. Peter Jenniskens now reports he has caught up with data reduction for this network.
2016, December 12 - The Geminids are in full swing. Koen Miskotte created this compilation of video-detected Geminids in the constellation of Gemini.
2016, November 13 - A strong 7.8 magnitude earthquake and several 6-mangitude aftershocks occurred north of Christchurch today. Ian Crumpton reports: "We had a relatively mild shake here, but no damage and no problems. CAMS are functioning normally. Most damage was to the north of us."
2016, November 12 - Peter Jenniskens reports that a March 2016 technical adjustment at Geraldine Observatory removed noise, eased the data calibration, and improved the yield of the CAMS New Zealand network dramatically. CAMS New Zealand measured a record 2,071 precise orbits in April. The graph above shows the radiant positions in sun-centered ecliptic coordinates.
2016, October 30 - Jim Albers reports that he was going through the Tehachapi CAMS data for October 24, 2016, and noticed a pattern in the maxpixel frame he had not seen in our data before. It was an extended area at the bottom left of the frame and several linear features up to the right. In the movie it turned out to be a single frame event. Historic lightning data from California shows there were lightning strikes over the Central Valley/Sierra foothills where the camera is pointed at that time. This suggests these are sprites.
2016, October 26 - Data reduction of Lowell Observatory's LO-CAMS network is complete until the end of September. Starting on April 22, 2016, a total of 5604 precise orbits were measured as well as some 2350 (with some duplicates) not-so-precise orbits. The latter include short tracks and tracks for which the speed was measured less accurately than 10 percent. The measured radiant positions from both data sets, in sun-centered ecliptic coordinates, are shown in the figure above.
2016, October 22 - Orionids are performing normal this year. No outburst has been reported.
