SOT Shift Report 2005-07-11 L2181 Duration: 11 Jul 2005 08:30 EDT - 11 Jul 2005 09:30 EDT 11 Jul 2005 12:30 GMT - 11 Jul 2005 13:30 GMT SOT Lead: Tom Aldcroft ======================================== Plan ---- Continue JUL1105C load. It is likely that this will be replaced by a TOO replan load today (see below). Study the wind of HMXB X1908+075, which may be a progenitor BH-NS binary; then continue the long-term monitoring of SNR1987A: 06336 X1908+375: Low N_H 2005:192:11:13:05.922 32.0 ACIS-S I5580 CAL-ER (59558) 2005:192:21:01:24.150 0.0 -- 05580 SNR1987A 2005:192:21:29:48.360 26.0 ACIS-S Events ------ No comm this shift Notes/Issues/Problems --------------------- Ops: In Radiation Zone NO Current SI ACIS-S Grating HETG Observation ID 06336 Target X1908+375: Low N_H Altitude 109.9 kkm Asc Radmon Disable 193/21:52z Next Radiation Zone 193/23:45z to 194/12:32z MP: - A one-day TOO (observe a HETE burst source) is being worked by FOT. Final approval is still pending. This would replace the HZ43 and M81 observations in this orbit. - Work on JUL1805 is on hold pending outcome of TOO decision. Eng: - ACA dark current calibration over weekend was successful; data analysis in progress. - On Saturday there was an ACIS threshold crossing plane latchup on FEPs 3 and 5. These were corrected by the FEP reset in the load, so the data loss was confined to obsid 5560. - The summer eclipse season is about to begin, with medium eclipses taking place on Tuesday night and Friday. Radiation: - Region 786 producing activity in the active to minor storm level due to the full halo CME associated with an M2 flare on 9-July. Over the weekend ACE P3 rates went as high as 10000 for several hours, but have since subsided. - Solar Activity Forecast: Solar activity is expected to be low to moderate. Region 786 may produce an isolated M-class event. - Geophysical Activity Forecast: The geomagnetic field is expected to be at active to minor storm levels with isolated periods of major storm conditions for 11 July due to the arrival of a transient shock from the CME associated with the M2 flare on 09 July. Predominantly active conditions are expected on 12 July, declining to mostly unsettled on 13 July. Other: - The Japanese X-ray mission Suzaku (formerly Astro-E2) was successfully launched over the weekend: http://heasarc.gsfc.nasa.gov/docs/astroe/astroegof.html Quicklooks ---------- 6326 Comet Tempel1 ACIS-S NONE OK 6327 Comet Tempel1 ACIS-S NONE OK 6328 Comet Tempel1 ACIS-S NONE OK 6329 Comet Tempel1 ACIS-S NONE OK 5594 RCW103 ACIS-I NONE OK 5527 RX J1308.8..
