Solar tornadoes not rotating after all, study shows

According to a team of European scientists, solar tornadoes are not rotating after all. Their new analysis of these gigantic structures, each one several times the size of the Earth, indicates that they may have been misnamed because scientists have so far only been...

Filament eruptions and impulsive M1.5 solar flare, geomagnetic storming expected due to CH HSS

Moderately strong solar flare reaching M1.5 at its peak time erupted at 12:53 UTC on July 3, 2015. The event started at 12:47 and ended at 12:53 UTC.The source was Region 2378, which rotated into the southwest quadrant yesterday producing innumerous C-class solar flares

Long duration M1.2 solar flare off the southwest limb produces large CME, solar radiation storm

A long duration M1.2 solar flare erupted from the vicinity of departing Region 2365, off the southwest limb, at 01:27 UTC on June 18, 2015. The event produced a large Coronal Mass Ejection (CME) and is currently causing solar radiation storm on Earth, reaching S1 (Minor

Large solar prominence on the northwest limb

A large prominence lifted off the northwest limb on July 21, 2013 and generated a Coronal Mass Ejection (CME), directed to the north and away from Earth.    STEREO Ahead and STEREO Behind COR2 images show the prominence flaring on July 22, 2013

M1.0 solar flare erupted from AR 1760

Impressive M1.0 solar flare erupted at 20:00 UTC on May 31, 2013. Event started at 19:52 UTC and ended at 20:06 UTC. The source of eruption was Active Region 1760. This region is small but appears to have a large amount of shear in the central spot. M1.0 solar

Large prominence eruption and strong C-class solar flare

Strong solar flare erupted on May 9, 2013 at 22:52 with peak at 23:15 UTC as C9.1 flare, just below M-class threshold. The event was centered around old returning Sunspot 1726. It will be on the visible solar disk in the next 24 hours when it will be designated as

Solar watch – Huge prominence eruption May 1, 2013

A spectacular prominence eruption was observed on the Sun on May 1, 2013 at 02:30 UTC. The event was classified as a farside eruption from active region located beyond eastern limb. This was the largest such event in quite some time now. Powerful blast was unleashed

Huge solar prominence erupted off the southwestern limb - non Earth directed CME

A huge magnetic filament erupted off the Sun's southwestern limb during the early hours of February 27, 2013. Most of the plasma looks to be headed away from the Earth though. On the Earth side of the Sun, Active Region 1682 developed a 'beta-gamma'

"Dragon Tail" - Huge filament eruption - January 31, 2013

A large filament stretching hundreds of thousands of kilometers erupted on Thursday, January 31, 2013. The eruption lasted about 4 hours and was located in the northeast quadrant of the Sun.The following SDO video shows a variety of views of the break-up of this

Ring-shaped prominence and Earth directed CME erupts from Sun - January 31, 2013

An Earth-directed Coronal Mass Ejection (CME) on January 31, 2013 (07:09 UTC) was accompanied by a large prominence eruption best visible in light with a wavelength of 304 angstroms. NASA's Solar Dynamics Observatory captured this footage from 10 p.m. EST (03:00 UTC)

Prominent view

The Sun is constantly roiling with nuclear heat and intense magnetism that make sunspots, flares, coronal mass ejections, and all sorts of space weather. When directed toward Earth, those solar blasts can disrupt satellite and radio communications, damage our

Large prominence eruption and C8.4 solar flare - November 16, 2012

At 07:51 UTC, November 16, 2012 a C1.4 solar flare peaked from Active Region 1613. About the same time, a large solar prominence was observed off the Sun's eastern limb. Prominence produced Coronal Mass Ejection (CME), however it does not appear to be Earth directed.

Sun produced spectacular plasma prominence and backsided M1.0 flare

Solar activity is moderate. Three C-class events were observed overnight and giant plasma filled prominence occurred on the southwest limb. M1.0 solar flare was registered around 02:11 UTC but it was not associated with numbered active region. Amazing plasma filled

Weak CME impact caused unsettled geomagnetic field levels

A weak CME shock was observed in the solar wind by the ACE and SOHO/CELIAS instruments on October 31st afternoon around 14:45 UTC. The solar wind speed jumped up from 280 km/s up to 370 km/s and also the solar wind density increased. Initial solar wind velocity had

Solar prominence observed at eastern limb

Solar activity was at low levels. The largest event during last 48 hours was a long duration C1 solar flare with a large prominence erupted on September 23 around 15:56 UTC from an area behind the eastern limb. It produces CME cloud with no threat to Earth.Some

Sun produced great solar filament eruption

Solar activity is expected to be low with a slight chance for M-class flares for the next three days, mainly from Region 1569. NOAA/SWPC estimates 20% chances of M-class solar flare. Region 1564 is crackling with C-class flares.The geomagnetic field was mostly quiet

Video of August 31 CME traveling through space

Anyone who observes solar activity here and there surely noticed spectacular solar filament on August 31, 2012. We saw amazing images presented to us by solar observatories in space and now SOHO combined all recordings from EUVI, COR1, COR2 and HI1 that give us clear

Geomagnetic activity at normal levels while another CME impact expected

NOAA/SWPC reported that the G1 (minor) Geomagnetic Storm has ended with the return of normal solar wind conditions. Currently solar winds blow at speed of 419.1 km/sec. Earthbound proton levels are now below the S1 Minor Radiation Storm threshold and geomagnetic

Large solar prominence off northwest limb today

A magnetic filament rapidly erupted on the sun today. Between 10:30 and 11:30 UTC, observers in Europe watched tendrils of hot plasma rocket away from the sun's NW limb. Debris from the explosion is not expected to hit Earth according to SpaceWeather. Solar

Solar prominence about 7 times the size of Earth occured on eastern limb

With no sunspots producing strong flares, the sun is officially quiet. But although the sun is officialy "quiet" multiple C-Class flares have been detected within the past 24 hours. C-Class flares continue to be detected around various locations on the visible solar
