Hathaway ongoing failed solar prediction
Waiting on NOAA / NASA to produce their December numbers at colossal cost to taxpayers, then update the now famous Hathaway “ever-moving prediction”. There is an animation at the excellent Anthony Watts web site.

  1. Both are an index of sunspot numbers, just calculated by different research groups.
