COMMENTS/CHANGES:

MISC: N/A

NOAA-15: There was relatively little change in the performance of the NOAA-15 bus & payload subsystems during the past week with the exception of the following:

The spacecraft is performing nominally in RGYRO mode with JFILT. Yaw errors are approximately +/- 1 degree (See Figure 1).

NOAA18 SEM TED proton and electron bias voltages were increased by one count to level 5 and level 5 respectively 27 Aug 2013 (13/239) at ~17:33 UTC.

Nominal performance observed from NOAA-18 MIMU1. MIMU pressure has been dropping at a linear rate for 4 years (See Figures 2 & 3). The MIMU1 Z axis LIM reached 0.85 µamp on 24 July 2013. Present value is 0.779 µamp. At the preset rate the LIM will be down to the critical value of 0.734 µamp by 05 October 2013 (best case). The Y axis LIM is down to 71.5% since 20 September 2012 (12/264).

NOAA19 SEM TED proton and electron bias voltages were increased by one count to level 4 and level 2 respectively 27 Aug 2013 (13/239) at ~18:12 UTC.

N19 HIRS Channel 14 radiometric counts continue to come in out and of being saturated though more time is spent at saturated levels as the filter wheel current and temperature vary. Also, Channel 17's Earth count maximum is hitting the saturation value as well as the maximum Space Position values (See Figure 4 & 5).

Nominal performance observed from NOAA-19’s MIMU2 (See Figure 6).

MetOp-A: There was relatively little change in the performance of the NOAA Instruments on MetOp-A spacecraft during the past week with the exception of the following:

MetOp-B: There was relatively little change in the performance of the NOAA Instruments on MetOp-B spacecraft during the past week with the exception of the following:
