Definitive Observations of the Young Accreting Star TW Hydrae. RADIATION SUMMARY ----------------- Solar soft proton flux is very low (http://www.srl.caltech.edu/ACE/ASC/) Significant solar activity: At midnight there were 3 spotted regions on the visible solar disk. The solar flare activity level was very low. No C class events were recorded yesterday. (http://www.dxlc.com/solar/). GOES x-ray flux: very quiet.. CMEs reported for past two days: Febuary 24-26: No obvious partly or fully Earth directed CMEs were detected in LASCO imagery.

We received and approved a TOO last night. It will be incorporated in either the MAR12 or MAR 19 plan. S/C: GOT/IST: We are working on the third string to do the daylight savings time update. We have run into some issues that we are dealing with. DATA: - SOT: MEETINGS -------- Harvey's staff meeting will be by email today.

Evaluation of QL data --------------------- Target: SI SOT Eval. ------------------- ---------- ---------- 3C279: obs7360_0 Detector: ACIS-S/HETG OK --------------------- NOTES/ISSUES/PROBLEMS --------------------- Here's a flashback to the February 22, 2000 Chandra Chronicles, just about seven years ago:: "Meetings of the American Astronomical Society are a time for astronomers and astrophysicists to exchange information about what's new and what's the buzz...In the January Atlanta meeting, the buzz was definitely about Chandra - 47 papers, 6 press releases, two press conferences, and numerous television interviews. Much of the buzz revolved around discoveries related to black holes. That in itself was not surprising. After all, one of the main justifications for building Chandra was to observe X-ray sources associated with black holes. What was surprising was the diversity of new results on black holes: the detection of an unusually faint black hole in the center of our galaxy; an unusually cool black hole in the Andromeda Galaxy; the unusual number of intense giant black hole sources in quasars and active galaxies, some of which may be older than the oldest stars... and the spectacular X-ray jets produced by black holes."
