(Times will be given in GMT on day 182. In general
times are rough, not precise.)

PLAN
Continue running load JUN2500d. Do ACIS-S observation of Kepler's
Supernova remnant, OBSID 116. Then perform CTI measurements
surrounding perigee passage. The week's load will then complete with
OBSID 99, ACIS-S on GRO J1655-40; OBSID 905, ACIS-I on the compact
group of galaxies HCG 90; and OBSID 310, ACIS-S on M31 transient monitoring. 

Next Comms:
         182:11:55 to 13:55
         182:20:00 to 21:45
         183:07:00 to 08:00
         183:15:20 to 16:20
         183:23:40 to 01:40
         184:08:15 to 09:15

NOTES/ISSUES/PROBLEMS
ACE 130-214 Proton fluxes steady or slightly decreasing at
~1000/cm^2-s-ster-MeV. Higher energy protons have steadily decreased
an order of magnitude over the past 24 hours.  
As of ~1400, 130-214 Proton fluxes start increasing to 3500, and
higher energy decrease has stopped. (I shouldn't have bothered to write the
first paragraph.) 


From the 9am status meeting:
	Passes on DSS-66 and DSS-16 resulted in problem reports, but 4
dumps successfully got all the data.
	JUL0200 load received final approval yesterday. Products for
JUL0900 will possibly be circulated today, otherwise Monday(?) for a
load review on Wednesday July 5, 2pm.

Quick look data:

A look at the two ACIS CTI runs, 62011 and 62010, verifies that the
T-plane lock-out problem was present on the former, as previously
noted, and was absent on the latter -- which was after FEP power was
cycled.
