G2 Geomagnetic storming in progress (Kp=6)

We are still experiencing effects of incoming CME generated from Sunspot 1520 which produced strong X1.4 Solar Flare on Thursday. A Moderate G2 Geomagnetic Storm (KP=6) is in progress right now due to an incoming CME shock. The geomagnetic field has been at active to

M6.3 solar flare, geomagnetic storm still in progress

Sunspot 1429  just produced a strong M6.3 Solar Flare. AR 1429 is now located in the center of the visible solar disk so this solar flare and its CME is heading straight toward Earth. The Bz Component of the Interplanetary Magnetic Field (IMF) is pointing south and

X1.7 solar flare - the 7th largest in Solar Cycle 24

Earth-orbiting satellites detected a powerful X1.7 solar flare today, January 27, at 18:37 UTC. The source was departing sunspot 1402 which rotate onto the far side of the sun, so the blast site was not Earth directed. Goddard Space Weather Lab's analysists say the

Sun's Active Region 1339 facing Earth

If you look in sun direction in time of sunset you could see the largest sunspots since 2005 . Active region 1339 is now visible from the Earth. These huge sunspots have been slowly rotating to face the Earth since November 3, 2011. The largest of these sunspots,

Eruptions this weekend could be Earth-directed as Sunspot 1339 turns toward our planet

Sunspot 1339 has quieted since Nov. 3rd when it unleashed an X2-class solar flare. Nevertheless, it still poses a threat for powerful eruptions. The behemoth sunspot has a "beta-gamma-delta" magnetic field that harbors energy for more X-flares. Eruptions this weekend

Big sunspot starting to release X-class solar flares

NOAA forecasters have upgraded the chance of X-class solar flares today to 20%. The source would be AR1339, one of the biggest sunspots in many years. The active region rotated over the sun's eastern limb two days ago and now it is turning toward Earth.The Radio

Long duration X1.4 solar flare took place at new sunspot

Earth-orbiting satellites have detected a long-duration X1.4-class solar fare coming from a new sunspot on the sun's eastern limb. The blast, which peaked at 1100 UT, produced a significant CME, but the cloud is not Earth-directed.

Geomagnetic storm in progress

UPDATE: The Geomagnetic Storm has subsided over the past few hours. However, the solar wind remains energized and occasional pulses of activity are expected for another 24 hours. Region 1283, the responsible party back at the Sun, decayed today. The Geomagnetic Storm

Farside CME activity continues

Solar Activity continues at fairly low levels with only C-Class activity taking place in the past 24 hours. Sunspot 1271 is the largest visible area and it may pose a small threat for an M-Class event.Farside CME activity continues and you can view all of the action

Active sunspot 1263 has left the Earthside of the sun

Active sunspot 1263, which just two days ago produced the most powerful solar flare of the new Solar Cycle (an X7), has left the Earthside of the sun. It is now beginning a two week transit across the solar farside. We can still see signs of its ongoing activity,

Largest flare of Solar Cycle 24 occurred today - Non-Earth directed X6.9

This morning at 08:05 UTC, sunspot 1263 produced an X6.9 solar flare, the third X-flare of new Solar Cycle 24 and the most powerful so far. NASA's Solar Dynamics Observatory captured the explosion's extreme ultraviolet flash:The brunt of the ex

Behemoth sunspot 1263 has almost doubled in size

Behemoth sunspot 1263 has almost doubled in size this weekend. A 28-hour movie from NASA's Solar Dynamics Observatory shows the spot developing a tail that has added some 50,000 km of length to the active region.This development may increase the likelihood of a stro

Sunspots 1261 and 1263 produce pair of M-Class flares - Expecting geomagnetic storm

An M1.1 Solar Flare took place around Sunspot 1261 at 03:37 UTC Wednesday morning followed an hour later by a M1.7 flare around Sunspot 1263 at 04:32 UTC. Stay tuned to this website for any further developments.A long duration M1.4 Solar Flare took place around
