This is a bright event and should be easy to do at hopefully 1x setting. It lasts a long time (well, 0.7s is long for such a bright star) so we should be able to get good detail on the shape of the asteroid, and also up's our chances of finding a moon if possible. The altitude is good, 41 degrees in Orion.
Be careful when reducing; the target star is only 40 arcsec away from a brighter neighbor star Avoid contamination from that star if possible
Alt=41, Az=240 in Orion, 10 deg below/right of Bellatix and left of the Shield

I observed from the cul-de-sac off Mar Monte Rd (La Selva Drive) under good calm conditions. Looked like a miss but not sure. Not reduced yet.
