The most recent Solar Storm Forecast from +TamithaSkov  - "The Sun has quickly kicked things into high gear this week with a massive active region that has fired 7 big flares and 3 partly Earth-directed solar storms in just a few days. We continue to wait for signs of the storms to hit Earth and are keeping a close eye for more flares. Catch up on some amazing aurora from the huge storm recently and see how the Sun will affect you this week."

"One small step for [a] man, one giant leap for mankind" - Armstrong. 46 years ago today on July 20, 1969, Apollo 11 astronauts Neil Armstrong and Buzz Aldrin landed on the lunar surface in the Sea of Tranquility. 6 hours after landing Neil Armstrong became the first human being to set foot on the moon. credit: NASA

Using a Black Hole Telescope to Look at the X-ray Sun: A space telescope designed to look into the furthest most reaches of space at some of the most energetic phenomena in the known universe has, once again, been turned to face our nearest star, producing a rare and beautiful insight to our X-ray sun. ...

Eruption! AR12371 does it again. The region erupted releasing an M7.9 (peaking around 8:16 UT). A nice coronal wave ripped across the solar surface and material was thrown into space giving us a CME that could have an Earthward component. We are waiting for models from NASA and NOAA. This video uses SDO 171 and 193 angstrom images to give us a good look at the flare, wave and some of the ejecta. This imagery shows us solar material at temperatures of around 600,000 to 1.5 million Kelvin. credit: NASA/SDO

OMG! Its corona is gorgeous indeed, but, at the same time it is very scary!!! Just to imagine temperatures between 600.000 to 1.5 million Kelvin's sounds insane... i guess it is a common for the sun to display its flare!   Wow! Thx NASA for sharing with us! ;-)

Geomagnetic activity continues to calm but there is more to come. Even as activity was picking up at Earth, region AR12371 erupted with another flare and CME. GOES registered X-rays reaching the M6.5 solar flare level at the peak time of 18:23 UT (2:23 pm EDT). This eruption produced a wave over the solar surface and a decrease in brightness around the region (called a dimming.) These are tell-tale signs of a CME. Here is the eruption observed by SDO in the 171 and 193 angstrom wavelengths of extreme-ultraviolet light. This shows us temperatures around 600,000 K and 1 million K respectively. credit: NASA/SDO

It is not over yet. The geomagnetic storm has lost a bit of steam but it is still going. Last night the Kp index reached 8 a couple of times with a storm level of G4 (out of 5). It is down to Kp 5 (G1) but it could still fluctuate back up to Kp 6 according to some forecasts. And there is another CME on the way from AR12371 (more on this later.) credit: NOAA

Aurora! G3 (STRONG) geomagnetic storm levels have been reached because of the arrival of a CME. The CME is associated with a filament eruption from Aug. 12. The CME reaching the ACE spacecraft roughly 1 million miles before Earth is visible in the solar wind data. High latitudes should get some nice lights well into tomorrow. Good luck aurora hunters! credit: NOAA

A stream of high-speed solar wind from a coronal hole has reached Earth. This has unsettled the magnetosphere giving us a G1 geomagnetic storm, G2 is possible. This could mean aurora at higher latitudes. Watchers look out! Here are traces of the solar wind data from the ACE spacecraft, which sits 1 million miles in front of Earth in the direction of the sun. The increase in speed from the stream is apparent in the data. credit: NOAA/NASA

Here is the CME impact from yesterday. An interplanetary shock was detected by the ACE spacecraft (our solarwind watchdog) at 12:57 UT (8:57 am EDT.) The shock was caused by the CME we had been expecting. This is several hours early but it is within the average error of plus or minus 7 hours. NASA scientists expected a strong magnetospheric compression and geomagnetic storm. And that would mean more aurora! Here is a look at the ACE solarwind data, which shows the sudden change in speed and density due to the CME shock. So far geomagnetic activity has been low until just now. Maybe there is more to com.  credit: NASA/NOAA

Here comes the next one. These are images from the SOHO/LASCO C2 and C3 instruments showing the CME from the eruption posted about yesterday. This CME left the sun with an average velocity of around 1100 km/s (~4 million km/hr). Based on preliminary heliospheric modeling carried out at NASA GSFC Space Weather Research Center, it's estimated that this CME will most likely impact Earth. Simulations indicate the CME will reach Earth today (6/24) around 18:18 UT (2:18 pm EDT.)  The CME comes from the same region (AR12371) as the previous CME that reached Earth on 6/22 giving us a descent geomagnetic storm. So all indications are that we are in store for some more geomagnetic activity and aurora. It could be comparable to the storm from 6/22. Aurora watchers - look up! (The LASCO images show the instruments C2 (red) and C3 (blue). Both images show the original data on the left and a difference image on the right. Difference images are created by subtracting two consecutive frames to see how the image has changed.) credit: NASA/ESA/SOHO

Last night many got an amazing auroral show. Some observed the ethereal lights at lower latitudes than many predictions. Reports have come in from as far south as Nothern Georgia in the US. The images shown here are from Massachusetts, Colorado, Virginia, Montana, Wyoming, Minnesota, South Dakota and Michigan in the US. All shared by spaceweather.com

Activity is decreasing for now, but this is far from over. So one more post before bed. Here is the spaceweather summary and forecast from Dr. Tamitha Skov. This gives an overview of current and some future spaceweather. She talks about the sunspot region, AR12371, that is the major culprit for recent activity. 

From Dr. Skov, "The Sun sends multiple M-flares and 3 solar storms our way this week as two regions on the solar disk keep us on our toes. The first solar storm should hit starting on June 22 with the next two hitting on June 23 and June 24. This means we will have strong aurora possibilities through the entire week. However the amateur radio bands and GPS operators will likely have further degradation along with the intermittent radio blackouts they are already experiencing during large flares. In addition, we are experiencing a radiation storm due to a solar eruption back on June 18. This ongoing radiation storm has dropped below storm levels, but further causes issues for amateur radio and GPS operators, especially at high latitudes. Learn the details of this radiation storm and the three solar storms that are on their way to Earth, how they will affect you, and see what else the Sun has in store for us this week.

Biography
I study the sun. My friends and family have always been excited by my work. In particular, they are especially interested because the Sun feels real and tangible. Of all the many interesting astrophysical objects in the universe the sun is the one object most people can feel through its light and heat. I have always enjoyed sharing my bit of knowledge about the sun with my friends, family and the public at large.

The explosion of social media gave me a perfect way to share my information and the information of others about the sun in a fresh and dynamic fashion. To leverage these new resources I envisioned a central website on which to share and organize the exciting past and present knowledge about the sun and its relationship to our lives. 

The main website, www.thesuntoday.org, connects to other social media sources like Google+, Facebook, twitter and YouTube in order to provide a broad reach to share rich and dynamic content.

I was joined by the other members of The Sun Today team, Ryan Milligan and CamillaSDO (www.facebook.com/NASA.Camilla.SDO) to bring you special guest postings. Linda Schenk (www.virtuallinda.com) works behind the scenes on design & strategy. Together we have been able to provide our fans with stories about past solar events and solar history as well as images and video of the current sun’s activity.

We have now been able to make my initial idea become a reality withwww.thesuntoday.org. It serves as the central hub and it connects to TheSunToday at Google+, FaceBook, Twitter and YouTube. We look forward to your questions and your comments. We hope to continue to share our love of solar physics with the growing Sun Today community. 

Enjoy!
