The Sun produced no flares in the past 24 hours. Active region NOAA AR 2716 decayed and lost its sunspots in the past 24 hours, leaving the visible solar disc spotless. The chance for a C flare in the next 24 hours is estimated at only 1%.
No Earth-directed Coronal Mass Ejections (CMEs) were observed in available coronagraphic imagery.
The greater than 10 MeV proton flux was at nominal levels in the past 24 hours, and is expected to stay at nominal levels in the next 24 hours.
Solar wind speed near Earth as registered by DSCOVR decreased from about 520 to 420 km/s in the past 24 hours. The Interplanetary Magnetic Field (IMF) was predominantly directed away from the Sun and its magnitude varied between about 1 and 5 nT. Bz was never below -5 nT.
Quiet to unsettled geomagnetic conditions (K Dourbes between 0 and 3; NOAA Kp between 0 and 1) were registered in the past 24 hours. Quiet to unsettled levels (K Dourbes < 4) are expected on July 23. Active geomagnetic conditions (K Dourbes = 4) are possible on July 24 and 25 due to the influence of an expected high speed stream from a negative polarity equatorial coronal hole, with a chance for minor storm intervals (K Dourbes = 5).
Today's estimated international sunspot number (ISN): 000, based on 25 stations.
