The molecular cloud associated with this HII region contains one of the richest young stellar clusters in the Orion region...an accurate determination of its X-ray luminosity function. RADIATION SUMMARY Observed Limit ----------------- -------- ----- ACE 2 hr fluence 2.9e5 3.6e8. GOES-8/P2 4-9 MeV protons `P4GM' 0.04 95 GOES-8/P5 40-80 MeV protons `P41GM' 0.01 0.78 *ACIS* Orbital fluence (since perigee) 2.5e6 1.0e9. EPHIN rates (cts/cm^2-s-sr) OBSERVED RADMON limit ---------------------------------------- -------- ----------- E1300 (electrons, 2.64 - 6.18 MeV): 0 10.0 P4GM (protons, 5.0 - 8.3 MeV): 0 300.0 P41GM (protons, 41 - 53 MeV): 0 8.47 ACIS focal plane temperature -119.7 at 8:35 am EDT. REAL TIME OBSERVATIONS GMT OBSID ----------------------------------------------------------------- 3 fids, 5 stars 1228 1878 Notes from 9 am meeting ------------------------ OPS: Passes 2 over the last day(s) Dumps current Data loss - Load is good -> 224/1102 CAPs - next passes 2000, 0345 Genesis launch: today at 12:13 EDT. Discovery launch: Aug 9 5:38 pm. Multi-Purpose Logistics Module Leonardo, crew rotation. MP: AUG13 load review approved. DSN pass is set, subject to whether Genesis launches today. S/C: CAP review Thursday for Monday's OTG-B patch uplink. GOT: - DATA: There is a new link for a text based Chandra snapshot: /pool14/handra/chandra1.snapshot. This is not subject to the psicorp problems. SOT: Solar activity is low. Proton flux is still dropping. 0 -20% chance of CME hitting earth in the next 96 hrs.

It is moving around quite a bit in the image display. This is probably just normal behavior for a star near our faint limit, but may be of interest to some.
