This event is a bit difficult. 12.4 will require 4x even in good conditions. The duration is only 0.38s and perhaps less since the north limit just skims West Cliff.
Alt=21, Az=94 in Cancer

I plan to try this one from home, which seems of more value given a north shift, than being on West Cliff and duplicating Kirk's site.
I didn't want to double-team Kirk's spot on West Cliff, and decided in the off chance it shifted north, it would be more valuable to observe from home. I recorded from the foot of the stairs, at 4x. Not sure what I got, but the sky was good and I was able to turn off the bright security light above the garage.
Trouble - my Lenovo computer ran out of hard disk space right before the event, apparently. And, there are no time stamps on the data due to inability to get
Got a recording from West Cliff area.
