A huge filament erupted from the sun producing a beautiful coronal mass ejection (CME) and solar energetic particle event. Around 21 UT, 9/29/2013 a filament erupted from the northwest quadrant of the sun. It started from the surface with a […]
A filament erupted on the backside of the sun and was observed by the EUVI instrument on the STEREO Ahead spacecraft. The eruption produced a CME detected by STEREO-A COR2, STEREO-B COR2 and SOHO LASCO C3 around 19:24 UT, May […]
Look at for Aurora tonight and tomorrow at high latitudes! Yesterday’s coronal mass ejection (CME) is expected to sweep past Earth in the last half of today (March 16, 2013) sometime around 18UT (+- 7-8 hours). Forecasts are from minor […]
A C-type CME was detected by STEREO-A COR2 at 5:39 UT on 11/10/2012. The estimated speed is ~900 km/s. Based on preliminary heliospheric modeling carried out at NASA GSFC Space Weather Research Center, it is estimated that the CME may […]
A CME is coming our way! A slow (only ~570 km/s Type-C), faint CME was detected by LASCO and STEREO around 15:24 UT 11/09/2012 and it is heading in the direction of Earth. Computer models indicate that the leading edge […]
At 17:40 UT, the Sun produced a C2 solar flare with a radio burst and a SCORE-C CME. NASA Goddard Space Weather Center predicts it will reach Earth 4/27/2012 at 5:49 UT with only minor impact. Currently, there is a […]
Sunspot group or active region AR11429 has almost rotated out of view but it still had enough energy to release an M7.9 X-ray solar flare, a fast coronal mass ejection (CME) and a solar energetic particle event (SEP). A […]
Sunspot group, AR11429 (Active Region), is at it again. When it first began its journey across the Earthward side of the Sun it released an M-class flare, an X-class flare and several more M flares, along with several CMEs. Early […]
UPDATE: Lovejoy survived despite most predictions to the contrary! Check out the videos below. A sungrazing comet called Lovejoy is near what will surely be its end. Sungrazers melted by the Sun is not really new. In fact, SOHO has become […]
A spectacular filament eruption from June 7, 2011 captured by the STEREO Ahead spacecraft with EUVI 304, Cor1 and Cor2. Happy Birthday STEREO!! October 26 ,2011 is the 5th anniversary of the launch of the STEREO mission and […]
At 01:50 UT, sunspot group, AR11283, produced an M5 solar flare and CME (coronal mass ejection) from near the center of the solar disk. The CME appears to be moving at an angle away from a path straight towards […]
Well, it has been a fairly quiet couple of weeks since all the activity at the beginning of the month. Early in the morning of 28 August 2011, a small filament erupted with an associated B-class solar flare. Here is […]
Our good friends and colleagues at Trinity College Dublin have created a 3D visualization of the propagation of a coronal mass ejection (CME). Using multiscale image processing and 3D visualization the team reconstructed the trajectory of an earth-directed CME observed […]
A View of the Active Sun with EUVI, COR1 and COR2 A very busy active region popped off about ten blasts of solar material over a two-day period (Aug. 31- Sept. 2, 2010). With this composited image and movie three […]
