Observing 'IC 310' with ACIS-I (obsid 5597). Current solar radiation levels are low (P3 below 25) but there is a lot of noise. 3-day Solar-Geophysical Forecast issued Dec 22 at 22:00 UTC Solar Activity Forecast: Solar activity is expected to be very low to low. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled with isolated periods of active conditions.

They are thought to originate at JPL, the symptom being duplicate command blocked generated. If we experience this the impacts will be nil to low. The problem is being worked. Mission Planning (Ken) - DEC2704A products reviewed, several issues found, B products out for e-mail load review S/C Engineering(Dan): - In yesterday morning's support we saw high TEIO temperatures and a 27V rail anomaly in which the voltage fell below 15 V and EPHIN current limited. This also caused some rise in the EPHIN E1300 channel data. - This is temperature related. We have some warm temperature observations coming up and should be watching this. We plan to re-evaluate the margin applied. SOT(Bill): - See above notes on radiation.
