Solar Activity
.24 hr Summary… Solar activity was very low with a spotless visible disk. No Earth-directed CMEs were observed in available satellite imagery.
.Forecast… Solar activity is expected to remain very low on 26-28 Feb.
Energetic Particles
.24 hr Summary… The greater than 2 MeV electron flux reached moderate levels. The greater than 10 MeV proton flux remained at background values.
.Forecast… The greater than 2 MeV electron flux is expected reach moderate levels on 26-28 Feb. The greater than 10 MeV proton flux is expected to continue at background values.
Solar Wind
.24 hr Summary… Solar wind parameters remained at mostly background levels. Solar wind speeds fluctuated between 335-365 km/s, total field averaged between 3-7 nT, Bz ranged from -3 to 5 nT, and Phi angle was mostly negative.
.Forecast… Minor enhancements in the solar wind environment are possible on 26 Feb due to potential interaction with a south polar extension CH HSS.
.24 hr Summary… The geomagnetic field was quiet.
.Forecast… The geomagnetic field may become elevated to unsettled levels on 26 Feb if a south polar extension CH HSS becomes geoeffective. Otherwise quiet conditions are expected through 28 Feb.
