SOHO Daily Meeting Minutes for Monday 01 May 2006 (DOY 121) Prepared by: Gini Heilman ANNOUNCEMENTS ------------- * The current RHESSI default target is on the following webpage: http://solar.physics.montana.edu/hypermail/mmmotd/. When selecting this target to maximize coordination with others, use campaign number 6850. * We are having some commanding issues today. The FOT have discovered that sometimes when they send 1 command, 3 of the same command end up on SOHO. This doesn't happen with every command (we think), but it is happening now as the FOT are testing it. We send 1 command, and JPL/the stations see 3 commands. So, please plan accordingly with your commanding until this problem is solved. * We learned this morning that on Saturday at 11:42 UT, the SSR turned all memory units off for an unknown reason. The FOT have been using the TR since then. This is being investigated and we will update everyone as we learn more.
