Propagation
Summary
Solar activity ranged from very low to high
levels during late July. Highest
activity occurred on the 19th with an M7 flare and a partial halo
coronal mass ejection.
Geomagnetic field activity ranged from quiet
to major storm levels. Activity on 16 July began at major storm levels and
decreased to unsettled levels as the day passed. Quieter to unsettled
conditions followed by the 20th.

Forecast of Solar and Geomagnetic Activity
The first half of August will see very low
solar activity, but with a slight chance of major flare activity from 30 July
to 13 August. The Solar flux is expected to be normal to moderate and on 3-5
august and on 11-15. Higher levels could
prevail on 6010 August. Geomagnetic
field activity is expected to be at quiet to unsettled levels with isolated
active periods up to 20th August.
Solar cycle Prediction
The current prediction for Sunspot
Cycle 24 gives a smoothed sunspot number maximum of about 60 in the spring of
2013. We are currently over three years into Cycle 24. The current predicted
size makes this the smallest sunspot cycle in about 100 years.
Meteor showers
Perseid Meteor showers are forecast from 30 July-18 August, peaking on
12-13th.
