Another CCD bakeout was started at 16:00 UT March 19, 2012. This bakeout will try to get more recovery for the lines that have changed the most since launch. 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 21 around 16:00 UT.
