The issue was initially detected on July 1, 2013, but since Sept 12, 2013, the issue has become increasingly more noticeable. Some images show only a single gap, other have several gaps. The root cause of this error is under investigation by the vendor. No telemetry violations have occurred, and all Sounder filter wheel telemetry data, including Filter wheel currents and period monitor, are nominal. Investigations are underway to determine the root cause.
