Spacecraft Status: Nominal
Spacecraft Anomalies:

  112/2300  Single DMA Failure over 1 format.

  113/0530  CEPAC ESU Data Request Error. Autonomously recovered

	    on-board.
Accomplished Activities: VIRGO, TTMH_TOMM_MMTOMH_02112, New

		         tracking star (6.95)
Planned Activities: RSL, VIRGO, TTMH_TOMM_MMTOMH_02113
Upcoming Operations: 5/1  ACU/CDMU Memory Dumps
Ground Anomalies:

  113/0722  39 minutes degraded data. Big pipe failed, swapped to
