1) Data obtained courtesy of the Institute of Ionosphere, Kazakhstan
2) Solar wind speed is preliminary (* on days with none or too few measurements from SOHO-CELIAS/MTOF PM, measurements from DSCOVR are used)
3) Ap and Kp values in red are based on the definitive Potsdam WDC data.
4) Flare enhanced measurements and measurements that most likely are invalid are replaced by other same day measurements ## (continuous QC process). Solar flux measurements that may be invalid are temporarily marked ** , while interpolated values are marked # .
