Forecast Discussion

Product: Forecast Discussion Issued: 2020 Jun 29 1230 UTC Prepared by the U.S. Dept. of Commerce, NOAA, Space Weather Prediction Center
Solar Activity
.24 hr Summary… Solar activity was very low. No Earth-directed CMEs were observed.
.Forecast… Solar activity is expected to continue at very low levels on 29 Jun – 01 Jul.
Energetic Particles
.24 hr Summary… The greater than 2 MeV electron flux and the greater than 10 MeV proton flux remained below event thresholds this period.
.Forecast… Both the greater than 2 MeV electron and greater than 10 MeV proton fluxes are expected to remain below event thresholds on 29 Jun – 01 Jul.
Solar Wind
.24 hr Summary… Solar wind parameters were nominal. Total field ranged from 3-4 nT while the Bz component varied weakly between +2/-3 nT. Solar wind speed ranged from 322-357 km/s. Phi angle was oriented in a predominately negative solar sector.
.Forecast… Solar wind parameters are expected to be at nominal levels on 29 Jun. On 30 Jun – 01 Jul, a negativity polarity CH HSS is expected to become geoeffective resulting in weak enhancements.
Geospace
.24 hr Summary… The geomagnetic field was quiet.
.Forecast… The geomagnetic field is expected to be mostly quiet on 29 Jun. Quiet to unsettled conditions are expected on 30 Jun – 01 Jul due to weak, negative polarity CH HSS effects.
