Decided NOT to restart loads last night due to continued high radiation, both moderately high ACE soft proton fluxe (25,000 at the time) and high rates in the EPHIN monitoring channels during yesterday afternoon's pass (E1300 in particular). Other issues of concern were the ACIS outbound CTI, which would have executed in the blind in high radiation, and the sensitivity of the scheduled observation to high background. Have initiated Replan C, which which would restart with the HST coordinated observation of the Crab, at 096:05:55 UT.

Not doing science now. - Did not uplink rest of APR0501 (Plan B) (see above) - Replan C products are out for load review at 1pm. Load starts at 096:0517. Uplink at 096:0300-0500 COMM - APR09 products done, but on hold until this week's loads are finalized (need to run continuity) S/C Engineering(Jeff): - Two stars not acquired on obsid 2062 turned out to actually be eliptical galaxies (per RAC)! This resolves this issue (catalog error). SOT(Bill): - ACE flux levels in 130-214 keV channel about 14,000 and slowly trending down until 9:30am when an uptick began. - EPHIN levels during the current pass (see above) would have triggered RADMON in the E1300 channel. DSOPS(Joy) - One quick look, interrupted obsid 1578 GOT(Chris): - All is OK.
