This is a high-value event, being a Trojan asteroid (in the same orbit as Jupiter). The target is faint, but the duration is long at 1.6s and the path appears to have a high rank. The R magnitude is 13.2. The altitude is 50 degrees in Aries in the west. Finding the target should be helped in the deep twilight by the fact it's close to a 7th magnitude star. Close, but not too close to be a problem. Maybe 1 arcmin away. The other challenge is that it happens with the sun at -10 degrees. That's dark enough to still get the event, but will require finding the target in twilight.
Alt=50, Az=251 in Aries, 10 degrees straight below the Plieades
I'll suggest using Aldebaren as your second align star.

This is a 111 frame PyMovie "finder", which does a very effective job of averaging out sky noise. Still, the target star is not at all visible at 16x, the highest setting I could do w/o sky brightness blow-out. And this is 11 minutes after the event and the sun angle now more like -13 instead of -10 at event time. This event was just far too tough. |
