Forecast Discussion

Product: Forecast Discussion Issued: 2019 Dec 02 0030 UTC Prepared by the U.S. Dept. of Commerce, NOAA, Space Weather Prediction Center
Solar Activity
.24 hr Summary… Solar activity was very low. The solar disk remained spotless and no Earth-directed CMEs were detected in available satellite imagery.
.Forecast… Solar activity is expected to be at very low levels on 02-04 Dec.
Energetic Particles
.24 hr Summary… The greater than 2 MeV electron flux was at normal to moderate levels and the greater than 10 MeV proton flux was at background levels.
.Forecast… The greater than 2 MeV electron flux is expected to persist at normal to moderate levels on 02-03 Dec with high levels likely on 04 Dec, in response to coronal hole influence. The greater than 10 MeV proton flux is expected to persist at background levels throughout the period.
Solar Wind
.24 hr Summary… Solar wind parameters reflected nominal conditions under an ambient solar wind regime.
.Forecast… Solar wind parameters are expected to remain nominal on 02 Dec. A minor enhancement is anticipated on 03 Dec as a polar-connected, negative polarity coronal hole becomes geoeffective. Waning coronal hole influence is expected on 04 Dec.
.24 hr Summary… The geomagnetic field was quiet.
.Forecast… The geomagnetic field is expected to be mostly quiet on 02 Dec. Quiet to unsettled conditions are likely on 03-04 Dec due to influence from the aforementioned coronal hole.
