The 2CEAHVPT MSID started out at 4.70 C After 1 hour of observing, the temperature has risen to 5.86C After 2 hour of observing, the temperature has risen to 7.05C After 3 hour of observing, the temperature has risen to 8.26C After 15ks of observing, the temperature had risen to 8.67C Some secondary science corruption was observed during the activity. This was expected behavior from the side-A electronics. SUMMARY: -------- The CAP executed nominally. During the observation, the HRC CEA HVPS bracket temperature rose from an initial temperature of 4.7C to a final temperature of 8.67C.
