We just had a "large burst" that the ERP on-line gc monitor found.
I received the alarm at approx. 3:55, Thursday morning May18, 1995.
It was a combined search result with multiplicity 1 over threshhold.
I found the time structure intersting and the position and box
distribution pretty random. The 2 large energies must be associated
with muons. Since this was the first time I was checking a burst,
I called Kate (who I knew was about to take the shuttle to the airport
for her flight to Italy) who also checked out this event.
In brief, just another background.
BTW, here's the output file from VXMACB for the latest burst. Aren't
we supposed to receive this automatically?
