Forecast Discussion

Product: Forecast Discussion Issued: 2020 Jun 30 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. There were no sunspots, and no Earth-directed CMEs were observed.
.Forecast… Solar activity is expected to continue at very low levels on 30 Jun – 02 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 at background or normal levels through 02 Jul.
Solar Wind
.24 hr Summary… Solar wind parameters were at mostly nominal levels. However, a brief enhancement occurred near 30/0115 UTC likely due to a weak, faint transient. Wind speeds increased to a peak of 393 km/s, total field increased to 5-6 nT, and the Bz component briefly reached -5 nT. Phi was predominantly in a negative orientation with brief excursions into a positive solar sector during the aforementioned time frame.
.Forecast… Mostly nominal levels are anticipated for the period with possible weak intermittent influences from a negativity polarity CH HSS on 30 Jun – 01 Jul
.24 hr Summary… The geomagnetic field was quiet.
.Forecast… The geomagnetic field is expected to be mostly quiet for the next three days (30 Jun – 02 Jul) with isolated unsettled periods due to a weak, non-recurrent, negative polarity CH HSS.
