PLAN
----
Continue running load May1506B. Finish obsid 7191, an ACIS-I
observation of cl0405-4100 to measure temperature and gas mass in a
sample of high redshift clusters. Then do obsid 6631, an ACIS-S/HETG
observation of the galactic neutron star GX 340+0, to diagnose
accretion flow models and the origin of the kHz quasai-periodic
oscillations. 

Next Comms:
139:2135 to 2235
140:0345 to 0445
140:1050 to 1130 DSS-27 PIT 
140:1050 to 1135
140:2140 to 2240
141:0245 to 0345

NOTES/ISSUES/PROBLEMS
From the 9am status meeting:
Three supports over the past day, no issues. One SCS uplinked,
on-board loads good until 141:23:44.
MAY2206B products were signed off yesterday, products will be ready
for uplink today.
The spurious LAE reading occuring on day 137, and reported yesterday,
has been traced to a double-bit error.
Tomorrow noon through 1am Monday, the IVODS will be down.
