Finish obsid 8516, an ACIS-S observation to measure variability in the nucleus and first knot of the M87 jet, in coordination with TeV observations. Then 8275, a low energy calibration observation of HZ43 for the HRC-I/LETG. Then 7829, an ACIS-S/HETG observation of the Seyfert galaxy NGC 4151 to study the X-ray absorbing gas and the outflowing wind.

EPH temp: 103.64 degF EPH 27V: 11.47 NOTES/ISSUES/PROBLEMS From the 9am status meeting: Nine supports over the weekend, no issues. Two segments of MAR1907C were uplinked, on-board loads good until 081:20:30. Three pre-approved CAPs were run, setting short eclipse flag true prior to the partial lunar eclipse, setting it false after the eclipse, and disabling SCS29 which is done after the end of eclipse season. MAR2607 products are expected out today for a load review tomorrow. Lunar eclipse was nominal yesterday. Several limits were tripped due to extra heater activity. The exit timer timed out, so a flag has been set TRUE indicating a software disconnect of the batteries. This is totally benign, and indicates our timing estimate was off by about 1 minute. We will leave the flag at TRUE and discontinue checking this limit, until the next eclipse season. Solar protons are at background level, and the sun is expected to continue to be quiet. Quick look data: All data look okay.
