ACIS-S observation of the gravitational lens system APM08279+5255, obsid 2979. This afternoon will start load FEB2502B, with ACIS-S observation of the redshift z=1.786 cluster of galaxies around 3C 294, obsid 3445.

NOTES/ISSUES/PROBLEMS From the 9am status meeting: Operations routine over the weekend. Two load segments uplinked: on-board commands good through 059:10:30. All SSR dumps are current. MAR0402A products were circulated Friday for an email review today. Richard Logan started today in the TRW FOT/engineering group. He will specialize in mechanisms and science instrument interface, gradually relieving Rich Myers in these areas. Welcome to Richard, and thanks to Rich for assuming these extra duties when Andy left! Eclipse season has ended, with all eclipses being nominal. CAP(s) will be run to reconfigure EPS parameters. Solar radiation is low, not a concern. Tomorrow afternoon we will perform an ACA dark current calibration, operating the camera through the stored command loads for the first time for such a calibration. Quick look data: OBSID Target Time Comment ----- ------ -------------- ------- 3391 HDF-N 053:02:08 ACIS-I NONE Looks good. Completes 2 Msec survey, public data. 2588 VEGA 055:01:51 HRC-I NONE Looks good -- no obvious light leak. ------------------------------------------------------- Dan Schwartz, MS #3 das@head-cfa.harvard.edu phone: (617)495-7232 FAX: (617)495-7356 cell phone: (617)512-5627 pager: 877-693-7198 PIN 693-7198 or e-mail 6937198@archwireless.net -------------------------------------------------------
