• Several strong solar flares and CME’s seen at farside

    At least three large CME clouds were observed during last 24 hours but all of them were at far side so there is no danger for Earth, they are heading away from our planet. Old Sunspot 1564 was probably source of the flares. STEREO Behind COR2 recorded bright flash with

  • A pair of CMEs on the farside

    A pair of Coronal Mass Ejections are now visible in the latest STEREO Ahead COR2 images. The source of the first CME was located on the farside of the Sun. The second plasma cloud was the result of a filament liftoff near Sunspot 1450. The plasma cloud appears to be

  • Farside eruption on Sun’s northwestern limb

    Old sunspot AR1429 is still very active as it transits the far side of the sun. During the early hours of March 18th it produced a spectacular solar flare, blasted away from northwestern limb. Earth will not be affected by the CME cloud.Joint USAF/NOAA Report of

  • Polar magnetic disturbance, farside eruptions and auroras

    A disturbance is rippling through Earth’s polar magnetic field on March 1st. Bright auroras have been sighted in Sweden and Finland. Rob Stammes of the Polar Light Center in Lofoten reports about magnetometer needles start to swing. This magnetic storm came as a

  • A long-duration C3 solar flare at the Sun’s farside

    NASA’s STEREO-Behind spacecraft observed a significant eruption on the farside of the sun today. Although the blast was eclipsed by the edge of the solar disk, it nevertheless produced a long-duration  C3 solar flare detectable from Earth. The blast site is not far

  • Eruption on farside solar western limb

    Sunspot 1384, currently located just behind the sun’s western limb, erupted today around 14:45 UTC. It registered as a long duration C2.4 flare and it appears to be connected to magnetic filaments snaking over the horizon to the Earthside of the sun. This event

  • Strong activity on the far side of the sun

    NASA’s STEREO probes are monitoring strong activity on the far side of the sun. A spectacular CME erupted during the early hours of April 8th apparently from old sunspot AR1176. This is the second day in a row that the active region has hurled massive clouds into
