Over past weeks, various upgrades took place in the backstage. We further improved the primary scripts for the sunspot number calculation. We also improved the internal data flow. The biggest transition was also the full migration from our old server, which served for the past 10 years, to the new one after a full year of cross-validation (double calculation in parallel). Although those deep changes are largely invisible to the outside world, they now put a fully new engine into our sunspot number production!
In addition, we changed the graphical presentation of our 12-month ahead predictions for the SC and CM predictions and their Kalman optimization. The new plots now also display the uncertainty interval. We hope that you will appreciate this new clearer presentation! At the same time, we also included all the corresponding prediction data as text files in our "Data" section. So please, visit or "Data" and "graphics" pages.
