The target - E0102-72.3 - was observed by ACIS-I for 9 hours and 43 minutes, ended 17 hours ago, and is part of the proposal AO-27 Calibration Observations of E0102-72.3. The target - also called SNR B0102-72.3 - is located in the constellation Tucana and is a SuperNova Remnant. The source is so bright in X-rays that only one-quarter of the chip was used for the observation. More information on the target can be found at SIMBAD. See related observations: 31376, 31372, 31373.
This was a time-critical observation.
