More Starlink satellites and an exploding fireball

Although the main cluster of Starlink space junk passed over while the sky was still quite bright, I managed a few decent images. Later on I crawled out of bed at just after 1.00 am, spending half an hour looking for Lyrid meteors: I failed to see any. However, I thought I'd do a timed exposure of the region to the east of Cassiopeia (the 'W' shaped constellation!) to see if I could capture the Andromeda galaxy, M31. I didn't, but at around 1.10 I saw an amazing greenish exploding fireball.
