Latest revision 24 Feb. 1999 Spurious triggers 7409 - 7424 due to flight software upset. TJD 11231-11232 = February 22-23, 1999 A flight software upset (bit flip) occurred at TJD/SoD 11231/24986. The upset occurred in an area of the software where the background rates are calculated; this can affect trigger thresholds, etc. The effect was noticed when spurious triggers began occurring. The problem was fixed by sending a command to the spacecraft at TJD/SoD 11232/50849 to change the contents of the altered word back to the original value. As a result, triggers 7409 - 7424 are spurious and are considered accidental.
