This is a long event, and therefore good prospects in a moonless sky of getting good data. The path's southern limit isn't far off the coast at Pleasure Point, and the northern limit is through Redwood City. So Kirk and I are likely to get an occultation of only a second or so.

Dur=5.7s

Alt=45, Az=269. This may be do-able from the street out front of my place.

3.2 sec event for Metcalfia, 4x from home, not a full drop. There were high clouds nearby, but apparently the target area was clear.
