Solar Activity

I think that the weather in Mallorca is predominantly influenced by the moon. But the unstable weather pattern here over the last week or so with high winds may well have been a consequence of the recent geomagnetic storms on the Sun and its reported Full halo plasma cloud heading toward Earth. The outlook on continuing solar activity is currently unsettled. The weather men in Mallorca continue to give us Yellow Alert for coastal areas in the North of the island for today, with winds calming down from tomorrow.

The Solar Terrestrial Activity Report reported:

The geomagnetic field was quiet to major storm on March 8. Solar wind speed at SOHO ranged between 456 and 828 km/s. A strong solar wind shock was observed at SOHO at 10:53 UTC, the arrival of the CMEs observed after the X flares on March 7. The initial part of the geomagnetic disturbance was much weaker than expected. Although it is unpredictable what happens when two CMEs interact, it isn’t unusual that the magnetic fields carried along by the CMEs are partly neutralized in the merge process. The disturbance has intensified early on March 9 with major storm conditions observed 01-04h UTC.

whilst the Space Weather Prediction Center gives us the following Geophysical Activity Forecast:

The geomagnetic field is expected to be under the influence of the current CME through early on day 1. Unsettled to active conditions, with isolated minor storm periods, are possible is expected as the CME continues to wane. Early to mid-day on day 2 (11 March), the CME associated with today’s M-6 flare is expected to become geoeffective. Active to severe storm periods are expected with this event. Unsettled to active conditions, with isolated minor storm periods, are possible on day 3 (12 March) as conditions are expected to slowly dissipate.

The weather forecast for the beginning of the week promises the wind speed to be decreasing from the recent 24 knots (Thursday) and 20 knots (yesterday) to 16 knots (today) to 12 knots (tomorrow) and 6 knots (Monday), according to WindGuru.

Thank you very much, you wise men.
