COMMENTS: This Notice was delayed by more than 60 sec past the end of the trigger integration interval; COMMENTS: probably due to it occurring during a Malindi downlink session. COMMENTS: This is an image trigger. (The RATE_SIGNIF & BKG_{INTEN, TIME, DUR} are undefined.) COMMENTS: A point_source was found. COMMENTS: This does not match any source in the on-board catalog. COMMENTS: This does not match any source in the ground catalog. COMMENTS: This is a GRB. COMMENTS: This trigger occurred at longitude,latitude = 9.97,-5.53 [deg]. COMMENTS: COMMENTS: This trigger occured while the StarTracker had lost lock, so it is possibly bogus. COMMENTS: COMMENTS: NOTE: This is an ImageTrigger with a ST LoL, so it was NOT distributed to the world!
