Perseids 2013 – Multi-station meteor videography

Journal issue: 2015 August
Pages: 217–219

NEMETODE, a network of low-light video cameras in the British Isles operated in conjunction with the BAA Meteor Section and other groups, monitors the activity of meteors, enabling the precision measurement of radiant positions and, from the best quality data, the altitudes and geocentric velocities of meteoroids and their solar system orbits. The results from multi-station observations of the 2013 Perseids meteor shower are presented and discussed, including an estimate of the Perseids’ population index.

Equipment and methods
William Stewart (WS) Alex Pratt (ARP) and Len Entwisle (LE) employed the same equipment and methods as described on the NEMETODE website and in their paper on the 2012 Perseids. In early 2013 January WS commissioned a third camera and realigned his two original cameras to achieve better overlap with ARP. In the Republic of Ireland Mike Foylan (MF, Co. Meath) operated two Watec 902DMS cameras with 8mm f/0.8 lenses, and Michael O’Connell (MC, Co. Kildare) ran his Watec 902H and 12mm f/0.8 lens. LE’s meteor camera was active on the nights of August 10/11 and 12/13, recording to VHS tape. ARP post-processed LE’s tape via UFO Capture. (Continued...)
