SIGNIFICANT EVENTS:
Flash Report: Part 2 of the COS NUV anomalous shutdown recovery was successfully completed today at
129/15:58.
Part 2 entailed a slow, partial ramp-up of the MCP high voltage. The ramp-up was commanded in four
phases, stopping at plateaus of -500V, -1000V, -1500V, and -1750V. There were four minute waits at
each plateau. Then the PC voltage was ramped to -50V. An 1800 second time tag dark images was taken
during the ramps. Once the HV ramps were completed software global monitor were commanded to look
at X, Y, Z, W, OR, EV, and VE counts for one minute each during a dark time-tag exposure.
A review of all of the relevant NUV telemetry was done. All of the currents and voltages were as
expected. The events types and rates were extracted and are consistent with those collected during
SMOV.
At 129/15:58 the NUV was returned to hold and COS event flag 2 was set. Event flag 2 will be
cleared after the science data is analyzed; the dark images should be available for analysis at the
institute by 130/00:00. After the all clear is given by the COS Science Team and OR will be issued
to clear event flag 2, I expect this to happen around 130/01:00. The FOT has been notified and is
ready to execute the OR 1st thing Wednesday morning, likely during the 130/12:13 forward support.
Part 3 of the COS NUV anomalous shutdown recovery is scheduled for 130/15:34 - 16:51, it is similar
to part2 except the detector will be ramped to it nominal operating voltages
