Observing 'LAMDA AND' (obsid 3722) with HRC-S/LETG. Follow with 3 short ACIS observations and then safe for radiation zone passage at 205:1935. Radiation levels have been elevated for several days. Soft proton levels have been in the 4,000 - 6,000 range. (ACE real-time data has been unavailable since 205:0850, Back online at 8:30am EDT. HRC has been in the focal plane for most of this orbit, so soft proton levels are not as much of a concern. Effects of July 23 X4 flare and CME will be seen today (see forecasts below). At AOS EPHIN rates were well below trip. E1300 1.0 (10.0) P4GM 22.8 (300) P41GM 0.2 (8.47) SpaceWeather.com: HERE COMES THE SUN: On July 23rd, an X4-class explosion near sunspot 39 hurled a coronal mass ejection (CME) toward Earth. The expanding cloud could reach our planet as early as Wednesday and trigger geomagnetic storms. Sky watchers should be alert for auroras. SOLAR ACTIVITY ALERT: Sunspot 39 is remarkably active. In recent days it has unleashed two X-class solar flares, caused radio blackouts on Earth, and fueled an ongoing radiation storm. High solar activity will likely continue for the rest of the week at least. Stay tuned for updates. 3-day Solar-Geophysical Forecast issued Jul 23 at 22:00 UTC Solar Activity Forecast: Solar activity is expected to be moderate to high. Regions 36 and 39 both have potential to produce isolated major events. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to active on 24 July. Minor storm conditions are expected on 25 July with active to minor conditions on 26 July. These conditions are anticipated due to the X-class event observed today. The greater than 10 MeV proton event is expected to continue for most of the period. The energetic electron fluxes at geosynchronous orbit are expected to remain at high levels for the next several days.

Were not able to get any contact during this support - SSR-A filled up, swapped over to SSR-B - DSS-24 support at 205:0500 was OK, got good dump data from A - DSS-34 support at 205:1130 was OK, finished dumps from both A and B and switched back to SSR-A for record. - Dumps current, should be no loss of data - Will turn off SSR-B next pass if all data is received in-house OK - Associated with the swapover to SSR-B, there were 7 errors in error log incl a "226 error". Similar to errors seen during swap-over on day 30, 2001 * Had a SADA-A limit violation, thought to be associated with above errors * Last time these errors turned out to be caused by error in transfer of data from IU to OBC * FOT (Rich) investigating Mission Planning (Ken): - JUL2902A e-mail load review held, B products out for load review at 2pm today - AUG05 load in work S/C Engineering(Rino): - S/C is OK SOT(Bill): - See above notes on radiation DSOPS(Joy): - No quick looks today GOT/IST(Chris): - All but 2 workstations upgraded to RedHat 7.2/GRETA 1.2.2 - Next 2 (freefot1, toblerone) to be done prior to next pass at 2100UT Meetings/events: - 10am, Star working group - 10am, Ground system CCB - 1pm, FOT staff - 2pm, load review 3) Quick look data: Seq # ObsID It Target start time SI Grat Comment ---------------------------------------------------------------------------------------------------------- JUL2202C:
