Shift report A14 August 5 1999, 8:00am EDT, GMT 217:12:00

Pretty boring...........


Spacecraft Activities this shift
- Succesful IPS #4 burn !!!!!  Chandra is now in an orbit of 5,649 x
139,100 km !!!! Final evaluation of the performance of LAE 2 and 4
will take some time.
- ACA Dark Current measurements, this procedure monopolizes the ENTIRE
realtime TLM stream but leaves the stream to the SSR unaffected. Thus
in order to analyze the ACIS data from the 4th science run of the new
Internal Cal and Background measurement, we MUST rely on the dump data.


Future Events of Importance:
- ACIS Door opening - if there is no IPS #6 burn, the door opening may
ocurr on Sunday night/Monday morning


ACIS Activities this Shift
1. New Internal Cal Source and Background Measurement
   continuing from Yousaf's shift

- 3rd science run of the new procedure, ACIS-I, accept events from
S2,S3,I0,I3, reject only b255, event amplitude ~ 15 keV

FP temp = -118.7 C
OBSID: 62727

Start GMT 217:01:09
Stop  GMT 217:07:06

- 4th science run of the new procedure:: ACIS-S, accept events from
S2,S3,S0,S1, reject only b255, event amplitude ~15 keV

Altitude: 109,000 km
FP temp = -118.7 C
OBSID: 62726

Start GMT 217:07:12
Stop  GMT 217:13:00 [projected]

** NOTE, there will be large dropouts (4 dropouts of ~12 min each) in 
the realtime data in these data.  Including a dropout in almost all of
the bias data !!!! ***
