You may have noticed some banding in the solar radiation data over the last couple of days. When I asked John Mecikalski what was happening, he provided the following explanation:

“Over the previous few days, the NASA GHCC feed of GOES data has been corrupted by some nearby signal, which they cannot determine. Hence, for a period of time each day the data are messed up and noisy. NASA is working feverishly to determine how to correct this problem.”
