Farside blast, Southeast limb prominence, CME, Geomagnetic storming

For more than a week, solar activity has been low. Today, around 0600 UT, an active region on the farside of the sun broke the calm with a powerful eruption. NASA's Solar Dynamics Observatory recorded a massive cloud of plasma flying over the southwestern

A mild (Kp=5) geomagnetic storm is underway

This is the third day in a row that geomagnetic storms have circled the poles. A mild (Kp=5) geomagnetic storm is underway. It looks like it subsiding now. High-latitude sky watchers should be alert for auroras. The source of this activity is a high-speed solar wind

Subsided geomagnetic storm, new incoming CMEs

Sunspot AR1465 has developed a 'beta-gamma-delta' magnetic field that harbors energy for X-class solar flares. Because of the sunspot's location near the middle of the solar disk, any eruptions will likely be Earth-directed.Earth's magnetic field is quieting after

Sun-diving comet and Earth directed CME

A Sun-Diving was caught on the Soho satellite feed April 23rd, shortly after the comet's death plunge a large Halo coronal mass ejection (CME) was observed and appears to have earth directed components. Impact on the earths magnetic field is expected sometime April

Unusual magnetic changes in the Sun - The north pole of the Sun had started flipping about a year earlier than expected

While scientists had predicted that the next flip would begin from May 2013, the solar observation satellite Hinode found that the north pole of the sun had started flipping about a year earlier than expected. There was no noticeable change in the south pole.The

New sunspot formation

Solar activity is near moderate levels with C-Class flares being detected around a new sunspot that was quickly formed in the southern hemisphere on Tuesday and was numbered 1462.. Another region is forming just to the west of that location and is currently producing

Spectacular M1.7 solar flare at northeastern limb

A moderate solar flare reaching M1.7 took place at 17:45 UTC on April 16th. The eruption was centered around a returning region near the northeast limb. It was  one of the most visually-spectacular explosions in years according to Generated CME was

A pair of CMEs on the farside

A pair of Coronal Mass Ejections are now visible in the latest STEREO Ahead COR2 images. The source of the first CME was located on the farside of the Sun. The second plasma cloud was the result of a filament liftoff near Sunspot 1450. The plasma cloud appears to be

AR1429 on march 30 2012

Active region (AR 1429) returned but not nearly the behemoth it was four weeks ago

The active region (AR 1429), the source of many strong flares and geomagnetic storms in the beginning of March 2012, has completed its journey around the Sun and is peaking over the Eastern limb of the Sun. But it is not nearly the behemoth it was four weeks ago.The

Return of Sunspot 1429 only day ahead - Still very active on farside

Return of the Sunspot 1429 to Earth side is due in evening hours of March 28th by UTC, meaning further increase of an M-class event.Sunspot 1429 produced a number of significant and strong solar flares during mid March and is still very active. On March 26th

Big Sunspot 1429 still erupting, Sunspots 1445 and 1444 pose a new threat

In morning of March 24, a near M-Class flare took place around Sunspot 1445 at around 08:50-09:00 UTC. There was a gap in data on the GOES X-Ray Flux graph, however it was picked up on the EVE Diode X-Ray signal. Comparing it to yesterday's M1.0, it looks like this

Returning Sunspot 1431 produced moderate M1 solar flare

Old Sunspot 1431 is now rotating back into view off the southeast limb and is also producing solar flares. So far this afternoon it produced a minor C6.5 flare, followed by a moderate M1.0 event at 19:40 UTC. Various small sunspots did form including regions 1441, 1442

Sunspot 1429 blasted another CME while transiting the farside of the Sun

Old Sunspot 1429 continues to be active while transiting the farside of the Sun. This morning (March 21, 2012), AR1429 produced a solar flare which resulted in a bright Coronal Mass Ejection (CME). SOHO photographed the cloud expanding at 1550 km/s (3.5 million

Farside eruption on Sun's northwestern limb

Old sunspot AR1429 is still very active as it transits the far side of the sun. During the early hours of March 18th it produced a spectacular solar flare, blasted away from northwestern limb. Earth will not be affected by the CME cloud.Joint USAF/NOAA Report of

Sunspot 1434 unleashed M1.3 solar flare

Sunspot 1434 located in the southern hemisphere, produced a rapid M1.3 Solar Flare at 20:39 UTC on March 17, 2012. A Type II Sweep Frequency Event with a velocity of 1140 km/s was detected as well. Analysis of the M1.3 flare is ongoing to determine if it was

What does a solar storm sound like?

To get an idea what does a solar storm sound like, a University of Michigan researcher has created a "sonification" of measurements from two spacecraft during the most recent storm. The researcher who created it is Robert Alexander, a University of Michigan de

Rising activity on Sunspot 1432 - Two moderate M-Class flares (March 14/15, 2012)

A moderate M2.8 Solar Flare peaked at 15:21 on March 14, UTC, and was centered around Sunspot 1432 located towards the middle of the visible solar disk. Slow moving CME plasma cloud is seen in the latest STEREO Behind COR images and may be partially headed this
