Forecast of Solar and Geomagnetic Activity
29 June - 25 July 2015
Solar activity is expected to be at low levels with a chance for
M-class flare (R1-R2, Minor-Moderate) activity from 30 June through
24 July with the return of old Regions 2365 (S13, L=079) on 30 June,
2367 (S20, L=002) on 05 July, and 2371 (N13, L=302) on 11 July.
There is a chance for a greater than 10 MeV proton event from 11
July through 24 July with the return of old Region 2371 to the
The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be at high levels from 29-30 Jun and again from 08-19
July due to residual CME effects and recurrent coronal hole high
speed streams (CH HSS).
Geomagnetic field activity is expected to be at active to minor
storm (G1-Minor) levels from 06-08 July and again from 11-12 July
due to recurrent CH HSS activity.
