Solar Forecast

(last updated 02 Sep 2014 23:30 UT)

03 Sep 04 Sep 05 Sep Activity Low Moderate Moderate Fadeouts None expected Possible Possible 10.7cm/SSN 140/94 135/89 130/84 COMMENT: Solar activity has been at low levels with C class flare activity from region 2152(S16W11), the greatest at C3. Several CMEs were observed directed towards the east. These most likely originated from an active region just around the eastern limb. None of the observed CMEs are likely to be geoeffective. A large filament in the north-west quadrant lifted off at around 15UT. At present there is very little coronagraph imagery available to characterise the resulting CME. STEREO-B images suggest the bulk of the material is directed north of the ecliptic which is likely to mean any geomagnetic impacts will be minor, however these images alone cannot rule out a moderate event. Updates on this event will be given in the summary forecast throughout the day once more data is available. The solar wind speed remains at around 420 km/s with nominal IMF conditions. Flare activity is expected to be Low on day one rising to Moderate on days 2 and 3 mostly due to the region rotating onto the eastern limb which has been producing CMEs consistently over the last few days.

Solar Activity levels are explained in the IPS Solar Terrestrial Glossary.
