3-day Solar-Geophysical Forecast issued Sep 14 22:00 UTC
Solar Activity Forecast: Solar activity is expected to be very low through the period (15 - 17 September) with a chance for a C-class flare.
Geophysical Activity Forecast: Geomagnetic field activity is expected to increase to quiet to unsettled levels on day 1 (15 September) due to a coronal hole high-speed stream. A further increase to unsettled levels is expected on day 2 (16 September) with a chance for active levels due to the arrival of the CME associated with the filament disappearance on 13 September. Field activity is expected to decrease to quiet to unsettled levels on day 3 (17 September).

The Satellite Environment Plot combines satellite and ground-based data to provide an overview of the current geosynchronous satellite environment. Click on a data panel to open an updating secondary window. An updating Satellite Environment Plot window is also available.
Although these data are of interest to the satellite community, they do not include all parameters and energy ranges known to be associated with satellite anomalies.
