This page is normally updated once a day by Jan Alvestad. Solar wind speed is preliminary (* on days with too few measurements from SOHO-CELIAS/MTOF PM, measurements from DSCOVR are used). Ap and Kp values in red are based on the definitive Potsdam WDC data. Flare enhanced and erroneous solar flux measurements are replaced by other same day measurements (QC).
