Ground Anomalies:
110/1906 Lost 2 minutes of recoverable TLM due to a TGC
failure at D16.
110/2337 A RNS/SCP failure at SPC-10 resulted in 64 minutes
of lost TLM (including the 0000 magnetogram). Data
should be recoverable from the CDR.
111/1715 Late AOS from D27 (20 min) due to their azimuth
drive going to brake. Due to the uncertainty as to
when D27 would have data, the S/C was transitioned
