During the last 48 hours, Chandra completed observations of the
GTO targets E0102-72.3, Pictor-A, NGC 2516, Hydra-A,
RX-J0911.4+0551, IRAS 09104 and a series of calibration
observations of NGC targets. In addition the recently
discovered type 2 supernova in the galaxy NGC 1637 was
successfully inserted into the schedule and observed as a
Target of Opportunity.
The software patch to modify the on-board code to use the
B-side LETG potentiometer value in place of the A-side value
was uplinked and a test performed at 7am 10/3 to verify correct
operation. The test was conducted during the pre-belt ACIS CTI
measurements and verified that the correct value is being used
by the software.
During the next 48 hours, Chandra will pass through the
radiation belts, perform post-belt ACIS CTI measurements abd
continue with ACIS observations of the Coma cluster, Mkn 421,
Vega and GS 2000+25.
The spacecraft systems continued to operate nominally.
