A CCD bakeout was started at 15:00 UT March 12, 2012. Occasionally, the detectors are warmed-up (only to about 15 C) to increase/recover the response at some of the lines. The lines decrease over time due to exposure with EUV light and warming the CCDs has recovered sensitivity in the past. During the bakeout, ESP will continue making normal solar measurements. The CCDs will return to normal operation starting Wednesday March 14 around 15:00 UT.
