Subject:	SGP/NIMFR/C1 - Tube heater not functioning
DataStreams:	sgpnimfrC1.a0, sgpnimfrC1.b1
Description:	The tube heater is not functioning properly. On 6/27/06, site operations personnel indicated the heater plug was found to be disconnected (The heater became disconnected on 6/12/06). It was reconnected and while the head temperature returned to normal, the tube temperatures are still bad. The purpose of the tube heater is to help prevent condensation from forming on the window. The mentor has not noticed any problems with the data resulting from the tube heater malfunction. However, since the instrument is technically not fully functional, this DQR is being issued. A repair attempt was made on June 7, 2007 that resulted in the tube temperatures reaching at times into the upper 50s and sometimes even the lower 60s. The high tube temps influenced the head temperature causing it to move into the upper 40s and sometimes the lower 50s. The heater was repaired on Oct 11, 2007. Though repaired, the instrument was configured to keep the tube temp in the lower 20s (deg C). This is acceptable, though to keep with instrument specifications the setting was adjusted to keep the temps in the upper 30s (deg C). This occurred on 8 Jan, 2008.

DataStreams:	sgpnimfrC1.a0, sgpnimfrC1.b1, sgpnimfrlangleyC1.c1, sgpnimfrlangplotC1.c1
Description:	Values of direct_normal_narrowband_filter2 (500 nm) were erratic at times, likely the result of a poor connection in the signal. The erratic behavior is last seen on 20081101, before the connectors were cleaned.

Subject:	TWP/MFRSR/C1 - Calibration Drift
DataStreams:	twpmfrsrC1.a0, twpmfrsrC1.b1
Description:	Through this period we see significant drift in all of the MFRSR channels except the 862 nm channel. The most serious drift occurred in the 610 and 665 nm channels which suffered a loss in sensitivity of a factor of 5 or more over the affected period. The MFRSR head was replaced on August 27, 1997 during a RESET visit.
