Title: December Geminids and sigma Hydrids - night of 9th-10th December 2022
Post by: Rick on Dec 11, 2022, 11:00:14
54 meteors were captured by my Global Meteor Network camera during the night between 21:09 on 9th and 06:37 on 10thDecember 2022. Of those, 16 were provisionally identified as Geminids, 11 as sigma Hydrids, 4 as Monocerids, 3 as alpha Draconids, and the rest, including the brightest (with two explosive events) as sporadics.

Sadly, so far no matches for the brightest meteor have been found, so its orbit can't be determined. Some of the others have, however been matched, including the first of the evening which was seen through a gap in the clouds. It's this Geminid in the UKMon archive (https://archive.ukmeteors.co.uk/reports/2022/orbits/202212/20221209/20221209_210904.207_UK/index.html). Orbital analysis has determined that another bright one (https://archive.ukmeteors.co.uk/reports/2022/orbits/202212/20221209/20221209_222925.095_UK/index.html) was actually a Southern Taurid.
