Eng: - All OK SOT/Radiation: - ACE solar protons are very low (< 100). - Solar Activity Forecast: Solar activity is expected to continue at very low levels. - Geophysical Activity Forecast: The geomagnetic field is expected to range from quiet to active levels with isolated minor storm periods possible for days one and two (11-12 March). Quiet to unsettled conditions are expected on day three (13 March) as the effects of the coronal hole high speed stream wane. DATA: - QL's today: 09506 0 NGC3585 2008:071:02:15:59.497 60.0 ACIS-S NONE OK 09252 0 3CRR 252 2008:071:19:48:47.843 19.6 ACIS-S NONE OK GOT/IST: - Other: - Paul and the ACIS team have reported on the FEP anomaly during OBSID 7783: I believe we have collected enough information to present a diagnosis for OBSID 7783: [1] FEPs 3 and 4 attached to CCDs S2 and S4 reset on frame #2374 during OBSID 7783. This resulted in only 7359 s of the desired 23810 s exposure on these two CCDs. There should be no event data from these CCDs/FEPs after the point at which the FEPs reset. [2] The target and hence the primary science was on S3. S3 and S1 operated nominally for the entire observation and produced the full exposure. Therefore, I do not see any reason that this observation would have to be redone unless the GO can make an argument for the data on S2 and S4. [3] The following observation, OBSID 9272, appears normal. FEPs 3 and 4 reset as they should have at the beginning of a science observation and S2 and S4 produced seemingly normal data. [4] There is no action we can or should take to recover from this anomaly. The power cycling of the FEPs at the beginning of the following observation is the appropriate action to take to recover from the anomaly. Snapshot -------- Snapshot matches expected configuration.
