SOT shift report 2003-06-18 L1427 Written at 2003:169:15:19 UTC = 10:19 am Jun-18-2003 EDT End 11:00:00 AM EDT SOT Lead: Ed Kellogg PLAN ---- OBSID 04398, 1E 1207.4-5209 2003:169:09:04, ACIS-S LETG - FIRST MEASUREMENT OF THE GRAVITATIONAL REDSHIFT AT THE SURFACE OF A NEUTRON STAR. RADIATION SUMMARY ----------------- Solar soft proton flux is Low. . (http://www.srl.caltech.edu/ACE/ASC/) Significant solar activity: Solar flare activity was high. A total of 4 C and 1 M class events was recorded during the day. A solar wind shock was observed at ACE at approximately 04:30 UTC. This is likely the arrival of the full halo CME observed on June 15-16.(http://www.dxlc.com/solar/) CMEs reported for past two days: June 15-16: An X1 flare late on June 15 was associated with an extremely wide full halo CME. The CME arrived in the Earth's vicinity early today. June 17: A fast partial halo CME was observed in LASCO C3 images after a major M class flare late in the day. The CME could become a full halo CME as it expands further and could reach Earth on June 19.(http://www.dxlc.com/solar/, Jan Alvestad) Radiation Measurement Observed Observed/Limit --------------------- -------- -------------- ACE 2hr fluence 1.82E+06 1/197 (http://www.srl.caltech.edu/ACE/ASC/) GOES-10/P2 4-9 MeV protons `P4GM' 1.21E+00 1/79 (ftp://ftp2.sec.noaa.gov/pub/lists/pchan/G10pchan_5m.txt) GOES-10/P5 40-80 MeV protons `P41GM' 7.56E-03 1/103 (ftp://ftp2.sec.noaa.gov/pub/lists/pchan/G10pchan_5m.txt) *ACIS* Orbital fluence (since perigee) 1.77E+06 1/565 (http://asc.harvard.edu/mta/alerts/current.dat) EPHIN rates (cts/cm^2-s-sr) at last comm.

The new version will be reviewed by email today. S/C: The gyros are fine. We had a discussion with Kearfott yesterday. They don't see a need to do a cold restart at this time. We'll have a tagup tomorrow to discuss future actions. Kearfott feel that the success of the warm restart indicates we have a lot of life left in gyro 1. GOT/IST: We had a router problem on the ASVT link yesterday. It's fixed now.
