Welcome to the Wiki of the Sunspot Number Workshops.

Here you'll find the latest information about the meeting(s).

The SSN workshop is being sponsored by the National Solar Observatory (NSO), the Royal Observatory of Belgium (ROB), and the Air Force Research Laboratory (AFRL). We am happy to report that Frédéric Clette of ROB has joined Leif and Ed as a Co-Organizer of the SSN Workshop Series. We view the September workshop as the first step in an effort to provide the solar community with a vetted long-term (single) sunspot number and the tools to keep it on track. This will take a lot of work and we look forward to collaborating with each of you. We will hold a second workshop at ROB on Brussels in May 2012 and are considering a special Topical Issue of Solar Physics for the eventual joint publication of the SSN series and the accompany historical, procedural, and scientific papers. We look forward to seeing you in Sunspot. Sincerely yours, Ed, Frédéric, & Leif.
