2015, September 3 - Our manuscript "The established meteor showers as observed by CAMS" has been accepted for publication in the journal Icarus.
2015, August 31 - The CAMS-derived trajectory of the August 27 06:01:13 UT fireball has it move from 88 km altitude over Soledad to 47 km altitude over Greenfield (where it left the CAMS field of view) at a slow speed of 13.6 km/s, with possible meteorites falling in an agricultural area on a north-south line between Greenfield and King City, according to calculations by Peter Jenniskens. He assumed a meteorite density of 3.4 g/cm3, falling from 47 km altitude in the prevailing winds based on the mean of Oakland Intl. wind sonde data for 0h and 12h UT.
2015, August 27 - A bright meteor appeared at 06:01 UT today that was the first to be captured by the new DFN camera at Sunnyvale. It was seen from Palo Alto and other locations in California. The meteor appeared low in the south from Sunnyvale and was also captured at Lick Observatory. The pattern of dots is caused by an electronic shutter that adds a time code to the meteor trail. While the first station is operating nominally, the second station is still being prepped for deployment at Foresthill, with some issues requiring physical access to the box. Jim expects that the second station will be at Sunnyvale for another week or two.
2015, August 12 - Maximum of the Perseids today. Jim Albers reports that the first DFN camera was installed at Sunnyvale, after some back and forth with our Australian collaborators. The camera, before the light shield was installed, is shown to the right, next to the CAMS Spectrograph and CAMS Sunnyvale station. The CAMS Spectrograph contains an all-sky video camera under its glass dome that is used to recognize the appearance of bright events. Peter Jenniskens and Mike Koop deployed the second DFN camera from a temporary location at Fremont Peak Observatory, where a public night was held to celebrate the exceptional observing conditions for this year's shower.
2015, August 10 - In part based on CAMS verification of showers, 18 new showers were added to the IAU Working List of Meteor Showers. One shower (the Southern iota Aquariids) was moved back to the Working List for more study. The tally of established showers now is 112.
2015, August 7 - The first of four manuscripts on the results of the CAMS meteor shower survey, called "CAMS confirmation of previously reported meteor showers", was accepted for publication by the journal Icarus today.
2015, July 29 - Phil Bland of the Desert Firebal Network (DFN) project of Curtin University in western Australia has left us two all-sky cameras that are the automated 32 MPixel digital cameras used in the DFN. Plan is to set these all-sky cameras up in the CAMS network to test the accuracy of the DFN orbit determinations and as a testbed for future instrument development.
2015, July 28 - At the Meteoritical Society meeting in Berkeley, Scott Harlan and Peter Jenniskens announced the find of meteorites at Misfits Flat dry lake in Nevada. In Septebmer of 2013, Scott set out to recover meteorites from one of the CAMS-detected fireballs, only to find the local conditions too harsh to search. He then diverted to the nearest dry lake bed and found a meteorite within two hours. He went back 19 times and recovered 58 meteorites and meteorite fragments. Study showed these are all LL5 chondrites, but some appear to be older than others. This is still being investigated.
2015, July 14 - Peter Jenniskens presents results on the CAMS project at the Meteoroid Environment Workshop at Stanford.
2015, July 7 - Ian Crumpton and Peter Aldous report catching a slow-moving bright fireball today that may have resulted in a meteorite fall in a wide river valley north of Mount Hut in the New Zealand Alps.
2015, June 10 - SETI Institute REU and Campare student Mellissa Hannan arrived at the SETI Institute today to help in the reduction of the CAMS Spectograph data collected so far. Mellissa will work close with Pete Gural in trouble shooting the reduction software and prepare the data in hand for analysis.
2015, April 6 - At the SETI Institute, Peter Jenniskens has caught up with the CAMS data reduction and reports a tally of 232,000 at the end of 2014 and 241,000 at the end of February.
2015, April 4 - Pete Gural modified the Mosaic program to also plot the max pixel intensity files in gnomonic projection. The result is shown for Sunnyvale and Lick Observatory in these images of the bright March 31 meteor. The meteor moved from left to right through multiple camera fields.
2015, April 4 - Today, Jim Albers followed by pointing Sunnyvale towards Forresthill, tilting the box by 14.4 degrees towards azimuth 40 degrees from North. The figure shows the overlap. Southern fields are overlapped by Lick Observatory and Fremont Peak. For now, we will operate the cameras in this manner, expanding the CAMS network surface area.
2015, April 3 - A new phase in the CAMS meteor orbit survey has started. Yesterday, Jim Wray re-positioned the Foresthill camera box towards Sunnyvale. The figure shows the new layout of cameras.
