commanded safe mode entry.
A second attempt to recover WFC3 was successful
• recovered to PreHeat mode
• in preparation for Sunday's SMS173
Investigation of the procedure is underway

imaging have been completed
o CCD Dark & Bias Monitoring resumes 175/06:00 – 08:01 UT
Science. CProffitt
• This week we'll only be obtaining CCD darks and biases.
• Working splinter groups for
o Optical Contamination (needed to allow external
observations for STIS
 waiting to see analysis of WFPC2 mirror.
 Hope to decide Tuesday or Wed whether external
STIS CCD observations are OK.
 Need to know by Thursday morning whether
external CCD observations are OK.
 A time critical DD proposal needs to use the STIS
CCD on July 1.
o MAMA Safety (needed for any MAMA operations).
 Issue being worked
 May take a few days yet to complete thorough
analysis.
