A Solar Flare Heading Our Way

An active sunspot (1123) erupted early yesterday (Nov. 12th), producing a C4-class solar flare and apparently hurling a filament of material in the general direction of Earth. Coronagraph images from the Solar and Heliospheric Observatory (SOHO) and NASA’s twin STEREO spacecraft show a faint coronal mass ejection emerging from the blast site and heading off in a direction just south of the sun-Earth line. The cloud could deliver a glancing blow to Earth’s magnetic field sometime on Nov. 14th or 15th. High latitude sky watchers could see auroras on those dates. We can't use a HF black ou tomorrow because of the PA Beker Contest. Ugh...

Nice video of emerging sunspots few weeks ago.

  5. Hallo Paul, ging de contest (CW) goed? Ik neem aan dat je meedoet in de QRP sectie? Zelf heb ik de hele zaterdag aan het werk geweest om uiteindelijk de loop te kunnen plaatsen. Vanmorgen ter test even een QSO gemaakt met Engeland uiteraard met 5W. Dat ging uitstekend. Succes met de contest straks en ik hoop je te horen...73, Bas
