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. A miss. 2x setting.
I got a miss for 2000 HO4, 1x at Moran Lake March 4, no apparent event. I had a couple bad timestamps, the VTI lost PPS momentarily for some reason, but it was well before the predicted event time. PyOTE detectability tool reported an event as short as 0.160s would likely be detectable, predicted max was 0.74s.

Mar 4 9:13:52 2000 HO4 from Blue Ball Park used 2X no visible blink, Clear, Big moon ~ 90 deg away, slight breeze at event time. Registered location with OW Cloud Site Lng: -121° 57' 35", Lat: +36° 59' 39", Alt: 43 m according to OW Cloud Map
RN: Looks like this shadow managed to miss all 3 of us. Probably a south shift of at least a half path width.
