    really don't know, worth a research. But probably there's a limit to how fast those blades can spin before they overheat or something

    Should have Googled it first really!

    "When the anemometer registers wind speeds higher than 55 mph (cut-out speed varies by turbine), it triggers the wind turbine to automatically shut off to prevent damage..."

    Well, at least all this wind is creating plenty of green electricity: 44% wind; 20% Nuclear; 13% Gas: 13% Imports; the rest Biomass/Hydro

    Windy tonight but come Friday it'll be even windier, though not sure how much more those wind turbines can produce.

    Isn't there a point where it's too windy for them to operate safely? Just asking.

    UK Aurora Watch just gone red on their alert system, error or a unexpected CME Impact?

    It was expected, but not quite so soon, and loads of sightings up North.

    Apparently it was 2 CMEs rolled into one....

     

    From Spaceweather.com

    CME IMPACT SPARKS GEOMAGNETIC STORM: A cannibal CME, described below, hit Earth's magnetic field on Nov. 3rd at approximately 20:00 UT. Solar wind data from the DSCOVR spacecraft show a stairstep structure indicative of two or more CMEs pressed together. A moderately strong G2-class geomagnetic storm is underway now, and the storm could escalate to category G3 in the hours ahead.

     

    Typically clouded out here!

    Any one getting any thunder and lightning the reason I ask is because I use to lightning trackers one where the bug and the other is lightning pro and the both showing lightning strikes near bye

    Was there much snowfall yesterday in Shropshire and worcestershire? Just thinking about melt, and river levels further down towards Tewkesbury and Gloucester.

    11cm here on South Staffs/Shropshire border. Local river Worfe feeds the Severn near Bridgnorth. Heard reports of 13cm in nearby Telford.
