• Moderate M3.3 solar flare at northeast limb

    A new and active Sunspot is now rotating into view on the northeast limb. It produced a moderate M3.3 solar flare at 17:45 UTC on Friday afternoon. All of the other current regions have been stable since the C3.3 flare around 1423 on Thursday. The new and active

  • 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

  • February auroras and blue flashes

    A CME impact followed by a gusty solar wind stream have combined to produce bright lights around the Arctic Circle on Feb. 26-29.  Arctic sky watchers should be on alert for more auroras tonight. The green flash, the fleeting emerald light that sometimes appears

  • G1 geomagnetic storm in progress

    Interplanetary Magnetic Field (Bz) has been pointing south at times today (Monday) and combined with the solar wind at near 500 km/s, it has generated a minor G1 Geomagnetic Storm at high latitudes. Storm levels reached Kp index of 5. The geomagnetic field is expected

  • Weak CME impact sparks some auroras around Arctic circle

    A CME hit Earth’s magnetic field on Feb. 26th at 21:00 UTC. Brief outburst subsided before it reached geomagnetic storm levels. A geomagnetic sudden impulse was detected by the Boulder station at 21:41 UTC. Maximum levels of planetary Kp index was listed as 4, just

  • The weak CME impact, auroras still possible

    A CME hit Earth’s magnetic field on Feb. 26th at ~2100 UTC. The impact was weak and does not appear set to cause a strong geomagnetic storm according to SpaceWeather. A solar wind increase to near 550 km/s was detected by the ACE Spacecraft around 20:50 UTC. A

  • “Canyon of Fire” on Sun

    The eruption of a magnetic filament at the sun’s northeastern limb split the sun’s atmosphere during the early hours of February 24th, creating a “canyon of fire”. The glowing walls of the canyon are formed in a process closely related to that of arcade loops, which
