REAL TIME OBSERVATIONS GMT OBSID ----------------------------------------------------------------- none Notes from 9 am meeting ------------------------ OPS: Passes 33 over the last 12 day(s) Dumps current Data loss On day 001/1420-1520 the data had excessive corruption. Load is good -> 005/2305 CAPs 750F 355/1534 OBC checksum memory dump 740 361/1511 HRC recovery from SCS 107 675 361/2317 Enable SCS 107 Note SCS 107 was triggered by EPHIN on 360/0630. Operations resumed on 362/0733. Next passes 1700, 0215 MP: We built the DEC28B load to recover from the EPHIN shutdown. Start science was at ~362/1245. We will review the JAN07 load today at 2:00 EST. We are working on the next load. S/C: We continue to see EPHIN yellow limits. This is primarily due to pointing direction and being near perihelion. We are reviewing the situation with the scientists with the goal of revising the yellow limit and planning for the eventuality that we will reach the red limit - to see if we should revise the red limit. We had lots of ACIS DPA low power warnings. This is caused by a change in the ACIS operating routine. Rich Myers will modify the limit to eliminate spurious warnings. We are analyzing the OBC checksum dump from CAP 750F. GOT: The GOT has managed to recover the data from the 001/1420-1520 pass to within our specs. A DPR has been opened with JPL on this event. DATA: Lots of quick looks. There was an unanticipated offset of 3 arcmin in OBSID 2734. Norbert has looked into this and discussed it with the observer, concluding that it's acceptable. We are checking a related upcoming observation to see if it needs a pointing correction. SOT: Proton rates are high and falling. A full halo CME was observed in LASCO C3 images starting at Jan 01 20:18 UTC. The source of this CME was probably several days behind the northwest limb. An increase in the above 10 MeV proton event was observed early on January 2, and with no other likely sources, it would appear that the event which produced the CME was a proton event as well. However, no increase has yet been seen on the ACE nor GOES fluxes. There is a low chance of a CME arriving within 96 hrs and a high chance of M or X class flares in the next 48 hours.
