During the last 24 hours Chandra completed the observation of the GTO target SN1987A with ACIS-S and the HETG. An ACIS CTI measurement of the all 10 chips with the focal plane temperature at -120C was performed via real-time commanding at 9:15AM 10/7. The pre-belt ACIS CTI measurements will start at 6.30PM 9/7, belt entry will occur at 1.30AM 9/8 and the 9th eclipse of the season will occur at 2:51AM 9/8.
