PLAN
----
Continue running load APR1006B.  Finish obsid 7319, an ACIS-S/HETG
observation of DX Cha in the epsilon Chamaeleontis Group to obtain a
high-resolution spectrum of an Herbig Ae star. Then obsid 6872, an
ACIS-S observation as part of a monitoring series of the Seyfert type
1.8 galaxy NGC 1365, to hopefully study transitions from Compton-thick
to Compton-thin states. Then obsid 7246, an ACIS-S observation of the
classical T Tauri star DG Tau A, to probe the relation of X-ray
characteristics to the optical jet.

Next Comms:
102:2050 to 2250
103:0345 to 0445
103:1200 to 1300
103:2015 to 2115
104:1030 to 1130
104:1645 to 1745

NOTES/ISSUES/PROBLEMS
From the 9am status meeting:
Three supports over the past day. No issues. One SCS was uplinked.

APR1706A products were sent out yesterday. Load review today at 1pm on
  #1159 

The OCC web, occweb.cfa.harvard.edu, is down. This problem surfaced in
the past hour, and is being worked by the FST. This also prevents
access to greta.

ACE 115-195 protons have been about 10 times background level since
last weekend, but this is about 100 times less than levels of concern,
and solar conditions are expected to remain very quiet

Adam Frye has been appointed the new GOT manager. Congratulations
Adam, and many thanks to Michael Ambrose for his years of service in
that position.
