GOES-12 Anomaly
On Tuesday 4 December, 2007, the GOES-12 (GOES-East) weather satellite experienced an anomaly in its attitude following a scheduled North-South station keeping manoeuvre.
On Wednesday (2007-12-05) GOES-10 replaced GOES-12 as the GOES-East satellite.
CLASS is  now using GOES-10 data until the GOES-12 issue is resolved.
