Shortwave propagation reports


Forecast of Solar and Geomagnetic Activity
27 June - 23 July 2007

Solar activity is expected to be at very low to low levels. Isolated C-class flares are possible during 28 June - 11 July due to the return of old Region 960 (S07, L = 176).

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach high levels during 27 June, 02 - 05 July, and 16 - 17 July.

Geomagnetic field activity is expected to be at quiet to unsettled levels during 27 June - 10 July, though active levels may occur on 30 June due to a weak, recurrent coronal hole high-speed stream. Activity is expected to increase to quiet to active levels on 11 - 12 July due to a recurrent coronal hole high-speed stream. Quiet to
unsettled conditions are expected during 13 - 17 July. An increase to quiet to active conditions is expected during 18 - 20 July with minor storm periods possible on 19 July due to another recurrent coronal hole high-speed stream. Mostly quiet conditions are expected during 21 - 23 July.
