SOHO Activity: -------------- EOF Staff: R. Rosati: Commander ---------- Command file: 12.08.13.22:26:06.cmd.log Activity: --------- 1) Attempting to free Lya grating that has become stuck while trying to move the 1216 A line from pixel 750 to pixel 825. This attempt is the first since we conducted a test with mech power off. We will command the Lya grating to move directly to pixel 825. After a brief delay, the Lya grating finally moved to the desired position. Cycling mech power seems to have solved the problem.
