NOTES/ISSUES/PROBLEMS
---------------------
1) MTA snapshot not currently updating properly.  Rob says this is due to
   work being done on the MTA page links.  For working snapshot updates
   see http://asc.harvard.edu/~rac/snap/snap.cgi.

2) Full halo CME announced this morning has been declared a backside event
   by the LASCO folks (thanks, Rob).  So we can relax [a little] 
   regarding the possibility of a radiation action this weekend.

3) Chandra status at AOS:
