|Solar Indices Bulletin
|The Solar Indices Bulletin issued monthly contains the latest daily international
sunspot numbers along with several solar radio frequency daily measurements, especially
the Ottawa 10.7 daily solar radio flux. The bulletin also contains predictions of
future sunspot activity, based on the McNish-Lincoln prediction mode. The data are
compiled on a very fast schedule so that data from the month before are available
by 2 weeks after the month’s end.
