The effective sunspot number, or SSNe, products that have been available through this NWRA site since 1997 are no longer available as of 18 May 2024. This is due to a decision made in February 2024 by the National Center for Environmental Information (NCEI) Solar & Terretrial Physics Section to no longer provide real-time observations of the foF2 ionospheric parameter. We have as yet found no viable replacement for this source, so we are terminating the production of SSNe until a new source can be found.
