Soft proton levels are low, currently flux is about 100, but levels show occasional spikes (above 1000) due to "upstream" magnetospheric particle bursts (see below). *** Special Note on EPAM Proton Data: *** The EPAM LEMS120 instrument which provides proton data in the energy ranges 47-68, 115-195, 310-580, and 1060-1900 keV is oriented on the ACE spacecraft at 120 degrees off the sun-Earth line, back towards the Earth. A consequence of this is that "upstream" magnetospheric particle bursts are often seen in these data. These bursts are most noticeable in the lower energy ranges, can occur several times a day, and can last for tens of minutes. The proton data in the 761-1220keV range is derived from a different instrument (CA60) oriented more towards the sun and is typically not affected by these upstream bursts. 3-day Solar-Geophysical Forecast issued Feb 12 at 22:00 UTC Solar Activity Forecast: Solar activity is expected to be very low. Regions 551 (S08W68) and 554 (S10E12) may produce C-class flares. Geophysical Activity Forecast: The geomagnetic field is expected to be at unsettled to minor storm conditions through 13 February, under the influence of a geoeffective coronal hole high speed solar wind stream. A decrease in geomagnetic activity is expected 14 and 15 February as the coronal hole rotates out of geoeffective position.

CAP 750I, J dump memory (associated with CAP 910) - Dumps are current Mission Planning (Ken): - FEB1604B products reviewed, small issues found. C products out, should be signed off this morning - TOO products being worked this AM, out later today. - CAP to replace loads needs to be reviewed as well as TOO loads. - NOTE on TOO from yesterday: Because of a recent ToO request for observing a blazar, the FEB1604 load review was canceled yesterday. A new load that is rearranged to leave a time slot for said observation is being released now, with review at ~3 pm. There will be another load, identical, except with the ToO in that time slot, available. A final go-nogo decision will be made Sunday, depending on how much the blazar has faded. S/C Engineering(Dan): - Ran CAP 910, 750I and J. - There is a 1 count discrepancy in rates from HRC directly and from the OBC telemetry in the TDB (OBC higher). This will be looke dinto. - Momentum dump Monday morning at 10am EST.CAP review today. SOT(Bill): - See above notes on radiation. DSOPS(Joy): - Four QL's GOT(Ken): - All OK IST(Ron/Chris): - Clock testing today - Offline system 103. received, will be installed on 3rd string - Approval for several new workstations received at FDB yesterday.
