Shortwave radio propagation forecast

Forecast of Solar and Geomagnetic Activity
04 - 30 July 2007

Solar activity is expected to range from very low to low levels.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be at high levels during 04 - 05, 16 – 17, and 22 – 23
July.

Field activity is expected to be at quiet to unsettled levels during
04 - 10 July. 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 due to another recurrent coronal hole high-speed
stream. Mostly quiet conditions are expected 21 - 26 July. A weak
coronal hole high-speed stream is expected to rotate into a
geoeffective position on 27 - 28 July, and will result in quiet to
isolated active conditions. The field will return to quiet to
unsettled levels on 28 - 30 July.
