Nowcast and Forecast for August 9, 2017


Solar activity (CMEs and flares) was at very low levels today. There were no solar flares observed.  The average values for slar wind density, velocity and temperature are 7 #/cm^3, 420 km/s and 180000 K, respectively .

Solar activity (CMEs and flares) was at very low levels today. There were no solar flares observed.

The average values for solar wind density, velocity and temperature are 7 #/cm^3, 420 km/s and 180000 K, respectively .

Geomagnetic indices also don't point out to any geomagnetic activity.

ASSA model gives a probability of 13% for C and 4% for M level flares. X level flares are not expected.

ALERTS!!!

  • Electron flux at GOES with energies greater than 2 MeV exceeded 1000 particles/(cm2 s sr) and electron flux with energies greater than 0.8 MeV exceeded 10^5 particles/(cm2 s sr) over the past 24 hours which indicated that there was an alert for spacecraft surface charging. (iSWA)

  • Proton flux at GOES with energies greater than 10 MeV and 100 MeV didn't reach or exceed flux levels 10 pfu and 1pfu, respectively. That means, there was no Solar Proton Event alert for spacecrafts. (pfu: proton flux unit: #/(cm^2*sec)) (iSWA)

  • There is a data gap in minimum magnetopause standoff distance for the current day. (iSWA)
