---|---|
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. |
