Enhanced October Camelopardalids (OCT) activity on October, 5th, 2016

October Camelopardalids (218 OCT) meteor shower had been the source of unexpected outbursts in 2005 and 2006, on October 5/6, which were recorded with video methods (2005 outburst slightly appeared on radio data). The OCT radiant is circumpolar, as it is located at coordinates α ~ 166°, δ ~ +79°. No such returns were observed the following years, when observing conditions were favorable (2007, 2008, 2011 and 2013). Esko Lyytinen linked the OCT activity to a potential unknown long-period comet, and expected the calculated trail responsible for the 2005 outburst to be in the same position in 2016. An activity enhancement of the shower was thus expected on October 5th, 2016, around 14h 45m UT (for more information, see the Section 6 of the 2016 IMO Meteor Shower Calendar). Observers were thus on alert for potential OCT activity increase on October 5/6, 2016, and tried to catch this suspected outburst, which would mostly favor Western Asia. First results shows that the OCT outburst was well recorded on radio and video data. Using RMOB data, Hirofumi Sugimoto could clearly highlight short enhanced meteoric activity on October 5th, centered on 14h 45m UT, so exactly at the predicted time!

Satellite debris reentry over the Channel on Oct 2nd

Satellite debris reentry have been observed and filmed from Southern UK and Normandy (France) on October, 2nd, 2016, between 18h42 and 18h45 UT.

They were probably linked to the CubeSat Flock 2B 2 (NORAD 40951), which was planned to reentry a few hours later South of Australia, but which was just over the Channel on October 2nd, 2016, at 18h43 UT, when the reentry was spotted. The reentry was filmed by the Wiltshire video stations of the UKMon video network, as well as by Patrick Sogorb, in Savigny-le-Temple.

The BRAMS team needs your help to detect Perseid echoes in the Radio Meteor Zoo project!

On August 12, the BRAMS team has officially launched the Radio Meteor Zoo, a Citizen Science project organized in collaboration with scientists from Zooniverse:

The goal is to ask many people to detect meteor echoes in the BRAMS spectrograms during some meteor showers. This is an easy task that any person can do after reading a short tutorial: just a few mouse clicks to draw a rectangle around every meteor echo. And it's fun to do!

Picturesque overview of August 10/11, 2016 video meteors

Sirko Molau shared a nice overview of the meteors recorded on August 10/11, 2016 by his four video cameras REMO1 to REMO4 in Ketzür, near Berlin, Germany.

Short and strong outburst of the gamma Draconids on July 27/28

A short and strong outburst of the gamma Draconids occurred close to midnight UT on July 27/28, 2016. It was detected by CAMS Benelux and the CMOR radar and confirmed by preliminary video data from the IMO network.

CAMS BeNeLux recorded an outburst of gamma Draconids around 0h UT on July 28. Due to clouds, only 2 stations were active. In half an hour, 5 multi station gamma Draconids were recorded. More than 50 single camera stream members were registered in less than 2 hours.
