The following is a non-exhaustive list of the bursts observed over the last several days. DATE (DDMMYY) TIME, S. OBSERVED BY* FLUENCE, erg/cm2 DURATION, S.

We note that the burst on November 1, which was observed by Mars Odyssey/HEND, confirms the timing of that spacecraft to high accuracy. From now on, unless an exceptional burst occurs, we will issue IPN notices for groups of events during this period of activity, instead of for single events.
