M2.5 solar flare, CME expected on June 9 and 10

On June 7th at 0641 UT, magnetic fields above sunspot complex 1226-1227 became unstable and erupted. The resulting blast produced an M2-class solar flare, an S1-class radiation storm, and an unbelievable movie:Much of the plasma thrown up by the blast simply fell

Spectacular eruption on the Sun - M2-class solar flare

At 06:41 UTC today the Sun unleashed an M2-class solar flare from arround the sunspot complex 1226-1227. Substantial Coronal Mass Ejection was observed and was visually spectacular. The large cloud of particles mushroomed up and fell back down looking as if it

A sharp gust of solar wind hit Earth's magnetic field

A sharp gust of solar wind hit Earth's magnetic field at approximately 20:30 UTC on June 4, 2011. High-latitude sky watchers in both hemispheres should be alert for auroras. Solar windspeed: 495.9 km/secdensity: 2.6 protons/cm3 Planetary K-indexNow: Kp= 5...

Sun's active region turns toward Earth - geomagnetic storm in progress

The quiet sun is waking up. New sunspot 1226 emerging over the sun's southeastern limb is crackling with strong C-class solar flares. So far none of the blasts has been geoeffective, but this could change in the days ahead as the active region turns toward

Sundiving comet and coronal mass ejection

A comet dove into the sun on May 11th and seemed to trigger a massive eruption. Watch the movie, then scroll down for further discussion. A comet goes in; a CME comes out. Coincidence? Probably, yes, the sequence was coincidental. The comet disintegrated

Subsiding geomagnetic storm (May 04, 2012)

Earth is exiting a solar wind stream that has been stirring up geomagnetic storms around Earth's poles since April 29th. Over the past few nights, observers have seen auroras over the South Pole, Germany, Wisconsin andMichigan. The chances for more auroras are

Geomagnetic storm in progress

The geomagnetic field was unsettled to active at mid latitudes. Minor to major storm conditions occurred at high latitudes due to Coronal Hole (CH) high-speed stream (HSS) effects. Solar winds speeds were sustained above 620 km/s during the period. The greater than 2

Fast growing sunspot 1199

New sunspot 1199 is growing rapidly in the sun's northern hemisphere, ballooning in area by more than a factor of five during the last 24 hours. If the expansion continues apace, this active region could soon pose a threat for flares. Stay tuned. (SpaceWeather)
