Recent Video from SDO will make earthbound tornado chasers envious.
SDO recently captured some astounding videos of tornados on the surface of the sun. These are caused by the plasma and it’s interaction with the magnetic fields on the surface of the sun. You can see an obvious spin and a tornado like shape and even what looks like a funnels.
The video taken over a 30 hour period on February 7-8. 2012 shows a least 3 tornados.Until SDO was launched videos like this were not possible. The frames are taken 4 minutes apart. The science is great….but the video is just …

Video of Tornados on the Sun..too cool to miss
Solar activity, flares, CMEs low for now at least.
The recent intense and frequent solar storms have passed and were now experiencing a welcome low level of solar activity (unless your into looking at Auroras that is). The Solar X rays have basically flat line as the storms that were causing some of the most intense CMEs since 2005 have passed to the back side of the sun and are not facing us any longer. If the sun spots are still active in about 28 days when the sun rotates them around to be in our field of view again we can expect some more excitement.
In reality it will …
Possible chance of minor geomagnetic storms on Feb. 3rd
NOAA is predicting a chance for a minor geomagnetic storm for 2/3/12.
People in northern latitudes should be watching for Auroral activity as a result.

First Samples of Interstellar Material Beyond Earths Solar System
Interstellar Wind Makeup
NASA – NASA’s Interstellar Boundary Explorer , known as IBEX for short, methodically measures samples of the mysterious neighborhood beyond our home. IBEX scans the entire sky once a year, and every February, its instruments point in the correct direction to intercept incoming neutral atoms. IBEX counted those atoms in 2009 and 2010 and has now captured the best and most complete glimpse of the material that lies so far outside our own system. It has seen that the Galactic wind does not look like the solar wind made by our own sun.

STRONG X-RAY EVENT WARNING ISSUED X2 Class flare
Update – Departing sunspot 1402… unleashed an X2 class solar flare today. It is going to the back side of the sun and should not cause any more problems.
To see current Aurora information click Here
Potential Impacts: Area of impact consists of large portions of the sunlit side of Earth, strongest at the sub-solar point. Wide area blackout of HF radio communication, loss of radio contact for about an hour.

Solar activity high CME headed for Earth Jan 24
UPDATE 1/25/12 – The Alert has passed and the storm has subsided.
The second storm in a as many weeks has been seen a warning issued. This radiation storm could cause satellites to reboot. Model output suggests potential Earth impact midday on 24 January.
Active region on the sun has spawned an M8.7 eruption – nearly an X-flare, the most powerful type, toward Earth, due to arrive Analysts at the Goddard Space Weather Lab say the leading edge of the CME will reach Earth on Jan. 24 at 14:18UT (+/- 7 hours) that is 9:18am Eastern time.

Large solar coronal mass ejection CME to hit earth Saturday
M3.2 Class flare seen by several NASA satellites
See Live images of the sun here
See article about new flare on 1/24/12 here
Update 1/21/12 – The CME has passed and NOAA has removed the warning for a CME Event.
The CME is Earth directed with impact predicted for Jan. 21, 2012. Increasing sun activity let loose a long duration M3.2 class flare and coronal mass ejection (CME) between 15:15 and 16:30 UT (or 10:15 eastern) 1/19/12.
This video taken by the Solar Dynamics Observatory, shows a close-up of sunspot 1401 region as the flare erupts. The CME cloud lifting off is visible just past …
SDO sees solar breakaway prominence end
Source – NASA – A long, solar prominence that rotated into view almost two weeks ago finally became disorganized and broke away into space forming a nifty large loop as it did (Nov. 21-23, 2011). NASA’s Solar Dynamics Observatory (SDO) watched in extreme ultraviolet light as the magnetic forces that tethered it in place gradually became unstable, the prominence began to crumble, and eventually lifted off. The Sun is becoming more active as it approaches the solar maximum expected in 2013.

SDO Spacecraft Observes New Characteristics Of Solar Flares
WASHINGTON — NASA’s Solar Dynamics Observatory, or SDO, has provided scientists new information about solar flares indicating an increase in strength and longevity that is more than previously thought.
Solar flares are intense bursts of radiation from the release of magnetic energy associated with sunspots. They are the solar system’s largest explosive events and are seen as bright areas on the sun. Their energy can reach Earth’s atmosphere and affect operations of Earth-orbiting communication and navigation satellites.
Using SDO’s Extreme ultraviolet Variability Experiment (EVE) instrument, scientists have observed that radiation from solar flares continue for up to five hours beyond the main …
