Simmons" , Wayne Pryor Hi Ian, Sorry I haven't had a chance to contact you before now. Life has become pretty hectic in the last few months. Regarding C30 EUV observations, I should let you know where we stand (Karen has already done the first level review). Due to my time constraints, I was only able to get the EUV sky background into the C30 cruise period. We originally had planned to catch a truncated torus observation at the very end of the cruise sequence. However, this became much more complicated very rapidly. The POINTER software that I originally used for the observation designs is no longer usable on my systems. This inability to accurately characterize the torus period was combined with a short turn-around time for sequence-building and an additional requirement to coordinate the downlink strategy for the end of cruise with the Sequence and SPOT teams. To effect these coordinations, to increase command complexity with a change of the instrument state, and to switch from manual flushes (1 per day for the sky background) to automated downlink with flushes at the correct downlink format (format C - one flush per hour) was nearly impossible in the time constraint I had to submit the sequence. Hence, I opted for the sky background set of observations. Please accept my apologies for not being able to give you more than this and for being delayed in this feedback. The current plan has the 24EUV sky background command NORM,COUNT,3,01,CRUISE,24,18 preceeded by the sky background FPNT that we used in G29. There are 68 EUV packets over this time period, one per day. Let me know if you want more detail and I would be glad to talk on the phone about this.
