At this time we are not receiving images from AIA and HMI. The data is flowing from SDO to the JSOC, but the ground software is not creating the...

A C2.5 Solar flare took place at 14:59 UTC Monday around Sunspot 1105. There will remain the possibility of B-Class flares and perhaps another...

Alpha Sunspot 1101 continues to transit the northern hemisphere of the sun. This region is not magnetically complex and the chances for strong solar...

The latest 48 hour mpegs have been released on the website. They are available for all 10 AIA channels. Latest AIA 094 Latest AIA 131 Latest...

As the STEREO (Behind) spacecraft observed in extreme UV light, the Sun popped off no fewer than six eruptions over just two days (Aug. 14-15, ...

On Monday around 0500 UTC, SDO pointed toward Regulus, a bright star in Leo. Half of the solar disk was kept on the CCDs and Regulus was to be a...

A long duration C4.4 Solar Flare took place at 10:05 UTC Saturday around Sunspot 1093 and 1099 and a possible earth directed CME was generated as...

We are now including the HMI Dopplergrams and intensitygrams in the Sun Now section. Intensitygrams are images of the Sun in the red part of the...

The sun has a slight peppering of sunspots with now 5 regions visible for the first time. Sunspots 1093, 1096, 1097 and soon to be 1098 occupy the...

A Solar flare took place at 18:25 UTC around Sunspot 1093 and it registered M1.0. Sunspot 1093 is now in good position for any possible earth...

On August 1st around 0855 UT, Earth orbiting satellites detected a C3-class solar flare. The origin of the blast was Earth-facing sunspot 1092....

A long duration C3.2 flare took place around Sunspot 1092 on Sunday. In the latest Lasco C3 movie you can see an earth directed Coronal Mass Ejection...

While I was at work Tuesday afternoon, a shock detected by the Ace Spacecraft indicated the arrival of atleast one CME (Coronal Mass Ejection) caused...

A new sunspot now numbered 1092 rotated into view Wednesday. It is currently a simple sunspot with a small chance for a C-Class flare. Sunspot 1089...

Spacequakes Rumble Near Earth The article contines on...do read it! Vortices that swirl around earth, electric waves, ripples and whirls in...

Just as Sunspot 1087 has disappeared, a new sunspot numbered 1089 has rotated into view on the eastern limb. You can see the new images below. There...

Sunspot 1087 was numbered on Friday and was probably much bigger than it currently is. A few small sunspots are visible, but this region is mostly a...

Observations from NASA's twin Solar Terrestrial Relations Observatory (STEREO) spacecraft have allowed Naval Research Laboratory scientists to see...

When a coronal mass ejection (CME) erupts from the Sun, movies in extreme ultraviolet light often show enormous waves, spreading over a large area on...

A new sunspot has formed in the northern hemisphere of the sun and was numbered 1086. In the southern hemisphere, Sunspot 1084 quietly persists. A...

Britain could face widespread power blackouts and be left without critical communication signals for long periods of time, after the earth is hit by...
