Title: Meteors on the night of 25th to 26th July 2023
Post by: Rick on Jul 27, 2023, 20:54:42
This is a tracked stack of the meteors captured by my two Global Meteor Network cameras on the night of 45th to 26th July, 2023. Between them, the cameras caught 137 meteors. Some of the meteors were caught by both cameras.

Most of the meteors were sporadics, but the preliminary analysis identified 29 alpha Capricornids, 8 psi Cassiopeiids, 7 July gamma Draconids, 7 Southern delta Aquariids, 4 Northern June Aquilids, and one eta Eridanid. The brightest one (lower right) was a mag. -3.4 alpha Capricornid which was caught by 17 UK-based Global Meteor Network cameras. There's an orbital analysis of it on the UKmon site here:

Are the wiggly lines moths?

Moths, bats or birds, depending. Generally the smoother flight paths are birds, the really wiggly or spiralling ones are moths, and the rest are bats, but sometimes it's hard to tell until you look at the individual frames, and then you can might be able to tell by the shape of the wings or the way they're flapped. Generally, when I'm checking a night's captures, they all get marked as not-meteors, along with the occasional plane or helicopter...

All the not-meteors in this image are still there because there was a meteor in the same frame.
