SHB/SKYRAD/C1 - Water spots on IRT Lens

IRT Lens had water spots on it.  Spots were removed with ethanol on a
lens cloth. The	exact starting time is unknown,	but is conservatively
set to the time of the previous inspection time.

SHB/SKYRAD/C1 - IRT and SKYRAD operations problem

SKYRAD had operations problem and on 3/3/1998 the IRT was disconnected
to see if that would improve the performance.  The spare IRT was tested
but it had problems. The original IRT was reconnected on 3/07/1998 at
7 GMT.

SHB/SKYRAD/C1 - IRT Intermittent data loss

Intermittent data drop outs in this period, especially
towards the end. Replacement instrument was put in place
on 3/28/1998.

SHB/SKYRAD/C1 - IRT data incorrect

IRT data are incorrect.  Possibly result of abrupt temperature
and humidity changes.  IRT was replaced after third instance.

SHB/SKYRAD/C1 - NIP Skystand vibration

With winds gusting in excess of 20 knots, the stand may have
been shaking slightly. The snow	and ice	has melted away	around
the skirt of the ablation shield and underneath, so the Skystand
is not as sturdy compared to 2 weeks ago.  The NIP has a very
narrow view angle and a slight tilt of the platform may cause
the NIP to lose signal due to incorrect solar alignment. 

Since the exact amplitude of shaking is not known these data are
considered suspect.

SHB/SKYRAD/NIMFR/C1 - Solar Tracker Alignment

The solar tracker was not tracking but rather oscillating back
and forth corrupting the data for this time period.
