Shortwave radio propagation update



Forecast of Solar and Geomagnetic Activity
25 July - 20 August 2007

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 reach high levels during 25 July, 03 August, and 12 - 15 August.

Geomagnetic field activity is expected to at quiet levels on 25 July. Activity is expected to increase to quiet to active levels on 26 July due to a recurrent coronal hole HSS. Quiet to unsettled conditions are expected during 27 - 30 July. Activity is expected to increase to quiet to active levels on 31 July due to a recurrent coronal hole HSS. Activity is expected to decrease to mostly quiet levels during 01 - 06 August. Activity is expected to increase to unsettled to minor storm levels on 31 July due to a recurrent coronal hole HSS. Activity is expected to decrease to quiet to unsettled levels during 08 - 09 August. Another recurrent coronal hole HSS is expected to increase activity to unsettled to minor storm levels on 10 - 11 August. Activity is expected to decrease to quiet to unsettled levels during 12 - 15 August. Activity is expected to increase to quiet to active levels during 16 - 17 August due to a recurrent coronal hole HSS. Activity is expected to decrease to quiet levels during the remainder of the period.
