Subject: SHB/SKYRAD/C1 - NIP Skystand vibration
Affected Datastreams: shbskyrad60sC1.a1
Description 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.

Subject: SHB/GNDRAD/C1 - Domes covered with rain droplets
Affected Datastreams: shbgndrad60sC1.b1
Description Heavy rain and fog commenced on 07/01/98 (approximately 14:00). The operator reported on 07/01 at 23:30 that the domes were covered in rain droplets. Since the exact starting time is unknown, the last confirmed time of a clean dome is logged here. Furthermore, the operator did not report a cleaning until 07/04/98 so that is used as the end time for this period of questionable data.
