Several sunspots have popped up around the visible solar disk

Sunspots are emerging at several locations around the solar disk, peppering the Earth-side of the sun with active regions. Of particular interest is fast-growing sunspot 1282, shown here in an August 31st snapshot from NASA’s Solar Dynamics Observatory:AR1282 has

New sunspots forming, Venus-directed CME

New sunspots forming, Venus-directed CME

Yesterday, the Solar and Heliospheric Observatory witnessed a spectacular explosion on the sun that seemed to pass perilously close to Venus.As the movie shows, the CME passed harmlessly. There was no collision, and it wasn’t even close. Although Venus seems to be

New sunspot is emerging over the Sun’s northeastern limb

New sunspot is emerging over the Sun’s northeastern limb

A big new sunspot is emerging over the sun's northeastern limb. AR1271 has at least four dark cores and it is crackling with small flares. The sunspot's entrance was captured in this 24-hour movie from the Solar Dynamics Observatory: NOAA forecasters…

Another M-class solar flare

Another M-class solar flare

A second M-Class flare, this time a M2.5 took place at 03:54 UTC Tuesday morning around Sunspot 1263. This is in addition to the earlier M3.5 flare which we reported yesterday. The first flare produced a small, but fast moving (2010 km/s) Coronal Mass Ejection…

Behemoth sunspot 1263 has almost doubled in size

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

M1.4 Earth-directed solar flare took place

M1.4 Earth-directed solar flare took place

Magnetic fields above sunspot 1261 erupted this morning at 0648 UT, producing an M1-class solar flare. The blast also hurled a bright coronal mass ejection toward Earth. This movie from the STEREO-Ahead spacecraft shows the cloud racing away from the sun at almost

Solar tsunami and dark fireworks on the Sun

Solar tsunami and dark fireworks on the Sun

On June 7, 2011, Earth-orbiting satellites detected a flash of X-rays coming from the western edge of the solar disk. Registering only “M” (for medium) on the Richter scale of solar flares, the blast at first appeared to be a run-of-the-mill eruption- that is, until

Behemoth sunspots evolve

Behemoth sunspots evolve

The CME was not squarely Earth-directed and is not traveling at great speed, only minor geomagnetic storming is expected when the cloud arrives. A coronal mass ejection (CME) that billowed away from sunspot 1247 on July 9th could hit Earth's magnetic field on…

Spectacular eruption on the Sun – M2-class solar flare

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

Sundiving comet and coronal mass ejection

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
