This is a very good event. Good location in Taurus, late enough to not be bothered by the sun twilight. Bright star. High rank, and a likely positive. Unfortunately I will not be able to do it, because I'll be giving a talk on asteroid occultations in San Jose at the moment of the event. But, Karl is nicely inside the path and it should be a likely positive
Alt=48, Az=262 in Taurus. Close to Zeta Tauri and the Crab Nebula
Results:
Kirk and I were giving a talk at SJAA on Asteroid Occultations. Only Karl tried this one

Got a recording, might be a miss. Reductions in process...
April 5 9:58:22 Lassovszky Water Truck turn (Sally’s spot) not too cold 57 deg F, fairly dry 50%, mostly clear (thin wispy clouds low in south) seeing mediocre, moon just past 1st quarter ~25 deg away, slight breeze (mini-gust seconds after predicted time), 9.5 mag star so used 1/60, slightly out of focus; no noticeable blink at predicted event time.
Processing: No drop visible while watching frame-by-frame. Rick concurs: it’s a miss. In PyMovie: used Dynamic mask on Target and Refs, used aperture size 91, checked “process in field mode”, PyOTE keeps finding an event at point of wind gust (2 seconds after predicted event).
