Observing '3C 120'' (obsid 3415) with ACIS-S/HETG. Current radiation levels are moderate, proton flux about 700. Solar Activity Forecast: Solar activity is expected to be at moderate levels. Region 9742 holds good potential for M-class activity and is developing potential for a major flare.

GOT tracked it down, it turned out to be sim data from the DTF21 test facility at JPL. - No ls uplinked, still good thru 357:2255 - Dumps current - CAP 750E run to dump segment 2 (of 3) of checksum memory Mission Planning (Ken): - DEC24C products out, review after 9am mtg - JAN07 products will be regenerated after DEC24 is finalized. Plan a review Jan 2. S/C Engineering(Rino/Rich): - All is OK - ASVT testing later today. - Plan to run CAP750F to dump last segment of OBC checksum memory SOT(Bill): - Radiation flux level (soft protons) is low (600) - Spaceweather predictions are for low to moderate activity in the next few days, but with a potential for more activity later on. DSOPS(Jen): - One QL, see below GOT(Ken/Janet): - All is OK. - Telemetry database TDBP008 released and will be installed later on today. - Visio available now on new PC'S, need to reboot to be able to use it - Old PC's will be removed starting Monday Meetings/events: - 9:30am, load review 3) Quick look data: Seq # ObsID It Target start time SI Grat Comment ---------------------------------------------------------------------------------------------------------- DEC17: 700582 03143 00 NGC2110 2001:353:12:19:45.036 33.8 ACIS-S HETG
