Sun is active again: M1.6 flare & sundiving comet

A Solar Flare reaching M1.6 peaked at 03:25 UTC Thursday morning and appears to be centered off the northwest limb near Sunspot 1318 which is rotating out of direct earth view.Solar activity remains at fairly low levels with only small to mid sized C-Class flares

Minor geomagnetic storming underway

Minor geomagnetic storming underway

Minor geomagnetic storming (G1 on the Geomagnetic Storm Scale) is underway following the arrival at Earth of 1 or more Coronal Mass Ejections that erupted from the Sun late last week and into the weekend.  Activity is not expected to strengthen much beyond current

Double eruption on Sun

Double eruption on Sun

On October 1st around 10:17 UT, widely-spaced sunspots 1302 and 1305 erupted in quick succession, revealing a long-distance entanglement which was not obvious before. NASA’s Solar Dynamics Observatory (SDO) recorded the movie of the double blast:Since it was

Earth-directed coronal mass ejection expected

Earth-directed coronal mass ejection expected

A coronal mass ejection (CME) is heading toward Earth and it could deliver a glancing blow to our planet’s magnetic field on Sept. 22th around 23:00 UT. There are no large coronal holes on the Earth-facing side of the sun. High-latitude sky watchers should be alert for

STEREO-SOHO detected six coronal mass ejections

STEREO-SOHO detected six coronal mass ejections

On Sept. 19th, the STEREO-SOHO fleet of spacecraft surrounding the sun detected six coronal mass ejections (CMEs). Two of the clouds rapidly dissipated. The remaining four, however, are still intact and billowing through the inner solar system. Click to view a movie of

Geomagnetic storm in progress

Geomagnetic storm in progress

As predicted by analysts at the Goddard Space Weather Lab, a coronal mass ejection (CME) hit Earth's magnetic field at ~03:30 UT on Sept 17th. The impact sparked a moderate geomagnetic storm (in progress) and auroras around the Arctic Circle. High-latitude sky watch

New sunspot AR1295 is emerging over the sun’s northeastern limb and crackling with solar flares. The strongest so far, a C9.9-category blast, did something remarkable. Click on the arrow to watch an extreme ultraviolet movie from NASA’s Solar Dynamics

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
