I don't see how this can be a "new" prediction since we already know the results from 3/09 to 8/09 and they are much lower than the predictions.

Example August 09 is predicted to be 7.1, but the SDIC monthly report has it a zero.

Likewise the other results from 3/09 to 7/09 are off by at least a factor of 2.

I agree that "the experts" seem to be rather slow to change, yet again, their predictions! Sunspot prediction is a bit like weather forecasting where billions of pounds of computers are about as accurate as looking out the window.
