PLAN
----
OBSID 03578, A514 2003:069:11:48, ACIS-I NONE - X-RAY STUDIES OF
DYNAMICALLY YOUNG CLUSTERS OF GALAXIES - X-ray linearly flattened
clusters may represent an early stage of cluster evolution. With the
superior angular-resolution of Chandra, we can search for merger
shocks/cold fronts during this stage.

RADIATION SUMMARY
-----------------
Solar soft proton flux is Low. (http://www.srl.caltech.edu/ACE/ASC/)

Significant solar activity yesterday: Solar flare activity was low
yesterday. A total of 5 C class events were recorded during the
day. (http://www.dxlc.com/solar/)

CMEs reported for past two days: March 7-9: No obviously geoeffective
CMEs observed. (http://www.dxlc.com/solar/, Jan Alvestad)

Notes from 9 am meeting

OPS:
     Passes          8 over the last 3 day(s)
     Dump status     Current
     Data loss       None
     Load is good -> 72:22:40 UTC
     CAPs            -
     Next passes     069/2010-2210	DSS 46 
		     070/0445-0645	DSS 66 
		     070/1255-1355	DSS 24

MP: The MAR17 load products will be out later today or tomorrow morning 
for review tomorrow.

S/C:  A very minor deviation from the usual focus motor pulse width
modulation count of 1: it went to 2 one time last week. It could go as 
high as 16. Nothing to worry about.

GOT/IST:
     -

DATA:-

SOT: GOES x-ray flux: There was one minor C class event at ~09:00 UTC today.

MEETINGS
--------
A meeting to review plans for the ASVT move will be held today at
11:00 at OCC.
