Asteroid Occultation Summary Page for Santa Cruz Asteroid Occultation Observers

2026

Bright green = #1baa05 = positive occultation successfully recorded
Dark green  = #037E0E = Miss successfully recorded Miss  
Red              = #de0205 = equip or operator error/failures
Purple          = #A636F0 = Noble Effort: purple heart (wounded in battle) recipient! - successful set up and no mistakes, but star just too faint for data, or clouded out at last minute
black            = Either no attempt made, or partial efforts (like making my planning pages, etc) but clouded out before set up. But, I only record these here if there is another "Team Santa Cruz" observer who did set up; otherwise it's just one of many that are cancelled out for various reasons; making a planning page is not sufficient effort to warrant making a record of it here.

Bernard Huynh has become a prolific observer as well. I'm just too overworked to be adding all his observations on my pages, given the steep ramp-up in the number of predictions and the number of observations, especially from automated remote observing from Bernard. He has my great respect! But I will only be able to summarize his observing sometime after the end of the year. 

Jordan Brown is also now on the Santa Cruz occultation team, She's likely to head off to college elsewhere in summer '26.

CSV TD'd? Mean: Did you insure correctly time stamped CSV, or create new CSV inside PyOTE after 'manual time stamp'?. "u" means unreduced, so you can still do the manual time stamp'ing and 'save to CSV' inside PyOTE to create the file needed for sending to IOTA. 'n' means it's not been done but can be done by the reviewer using PyOTE log file showing the manual time stamps.
