Event-of-the-Day

Photo of the event-of-the-day for Thu 14 Aug, 2003.

This event is one that got tagged as being a possible pi->e nu event. Obviously this isn't a pi->enu, it is just some soft particles from upstream. The red and green clusters are all at the same time. The yellow clusters are from a beam positron that comes later.
