GLO STATUS

036/17:48 UT   Sun. 12:48 EST
Mission Day 002/12:26

Data Status:

The data quality looks very good! We have collected
dayglow, nightglowm, and aurora data. The primary operating
mode is to have the 8 deg slit perpendicular to the limb
with the low end of the slit at about 100 km tangent altitude
during the day and about 50 km altitude at night.  We are recording
a complete frame (spectra and filtered images) every 4 sec.
Each spectrograph frame has 24 altitude
samples and 5000 spectral samples (from 1000 to 10000 A).

Hardware Status:

The On-Board Tape drive (DRU) is still not coming on.
This is a small problem since we can still collect
16 Mbyte of data at a time and down-link it at 100 kbytes/s
It will mean that we collect only about 1/2 of the data
we had hoped for during the mission.

Housekeeping Board is still not working.
The internal temperatures and voltages are
monitored with the Housekeeping board.  This will not affect the
data.

High Voltage Power Supply has fixed itself.
This supplies power to the intensifiers.  During
the first day of the mission, it would turn
itself off every 20 min or so.  It has been
working fine for the last 36 hours.

Optical Limit switch senses the sun.
The Azimuth limit switch detects sunlight and
stops the Az mount.  This switch was overridden
with software and is no longer important.  The
switch worked fine at night.  No impact on
data collection.

All other systems are working fine.  We have been
collecting dayglow, nightglow, and aurora data every
chance we get.  The Shuttle has had a few problems and
as a result, NASA has been messing with the time-line.
When they are spinning the shuttle around to try and
warm up the various leaking thrusters, we have to
stop taking data.  This has limited our data collection
the most.
