Forecast of Solar and Geomagnetic Activity
09 September - 05 October 2019

Solar activity is expected to be at very low levels.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be at high levels from 09-13 Sep, and again from 27 Sep
- 06 Oct due to HSS effects. Normal to moderate levels are expected
on 14-26 Sep.

Geomagnetic field activity is expected to be at mostly quiet levels
on 09-26 Sep. Isolated unsettled periods are possible on 23, 26 and
30 Sep, and 01-03 Oct. G1 (minor) to G2 (moderate) geomagnetic storm
levels are likely on 27-29 Sep due to positive polarity CH HSS
effects. is the U.S. government's official web portal to all federal, state and local government web resources and services.
