Observing Hubble Deep Field - North (obsid 3391). Soft proton levels are moderate to low. Flux level at about 650 and slowly declining from peak of about 1500 yesterday. NOAA SEC: Solar Activity Forecast: Solar activity is expected to continue at moderate to high levels. We may continue to experience activity from behind the NW limb for the next day or so. Regions 9835 and 9830 have potential to produce M-class activity with a small chance for a major flare. No COMM this shift.

Day 55 has this configuration as well. - Rich Myers will be on ASVT today running SIM SEA reset response procedure. SOT(Bill): - Soft protons slowly declining. - Activity prediction is for "moderate to high". DSOPS(Joy): - Several QL's - Obsid 3441 QL quick look processing problem is QL software related, will be fixed by Joy et. al. GOT(Mike/Chris): - All OK. - Setup for ASVT now.
