Solar Forecast

3-day Solar-Geophysical Forecast issued Jul 17 22:00 UTC

Solar Activity Forecast: Solar activity is expected to be moderate for the next 24 hours with 1520 and 1521 as the most likely source regions. Activity and background levels are expected to decrease significantly by the second and third days as these regions rotate beyond west limb.

Geophysical Activity Forecast: The geomagnetic field is expected to be quiet for the next three days. Model results for today’s CME from the west limb indicate an interplanetary disturbance that is too far west to produce geomagnetic activity. The greater than 10 MeV proton event is expected to continue through part of the first day (18 July).

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.
