2) Solar
wind speed is preliminary (* on days with none or too few
measurements from SOHO-CELIAS/MTOF PM, measurements from SOLAR-1 are used)
3) Ap and Kp values in red are based on the
definitive Potsdam WDC data.
4) Flare enhanced measurements, unreported measurements, and measurements that most likely are invalid
are replaced by other same day measurements when possible ## (daily QC).
Solar flux measurements that may be invalid are temporarily marked **,
while interpolated values are marked # .
5) Suspected faulty measurement or incomplete observation.
6) Sunspot count temporarily using other data sources than SDO.
