I processed last nights data and got magnitudes of between 13.8-14.0 (Gaia g unfiltered) with a 0.12 mag spread – which is okay given it was initially viewed through a hedge and very low. Position errors were within the seeing disk.
Give it was moving at ~300 arc secs/min I used either 1s or 0.6s exposures. I think that was near perigee. It looks rather slower tonight.
