The Sun Today

Shared publicly  - 
 
How would you like to understand a fundamental process happening throughout the universe?

You can! The mission is studying magnetic reconnection, which happens in the atmosphere of stars, planets with magnetic fields and exotic objects across the universe such as black holes and neutron stars. MMS will unlock the answers on a small-scale using Earth as a laboratory. Scientists will share these discoveries with us, and then we too, will understand the process that happens on small and big scales, happening from close to home to the farthest reaches of the universe.

These images show some of the phenomena caused by release of energy through magnetic reconnection, a coronal mass ejection (SDO), a solar flare (SDO), the aurora, a black hole accretion disk flares, nebula around a neutron star (the last 2 are artist impressions.) credit: NASA

By looking close to home, NASA’s newest mission with provide a window to the universe.

Like stretched rubber bands, magnetic fields store energy that is released when the fields lines realign – explosively accelerating particles to nearly the speed of light.

This process of energy release from magnetic fields is called magnetic reconnection. Studying and understanding this fundamental process is the main purpose of MMS. This process creates interesting phenomena both near and far on objects with magnetic fields. It causes eruptions on the sun, it releases energy from matter disks around black holes and neutron stars into space, it even happens at the boundaries of the giant bubble surrounding the solar system, letting in charged particles from the rest of the galaxy.

The Magnetospheric Multiscale, or MMS, mission was created to study how magnetic fields around Earth interact with activity from the sun. The Earth has a magnetic field like a bar magnetic that is generated by its spinning liquid metal core. The magnetic field forms an invisible bubble around ...

T - 10 days until the launch of NASA's Magnetospheric Multiscale, or MMS, mission. This group of four identical spacecraft will study how magnetic fields around Earth rearrange themselves to explosively release energy -- a process known as magnetic reconnection. 

The MMS mission will provide the first three-dimensional views of this fundamental process that can accelerate particles to nearly the speed of light. MMS uses Earth's protective magnetic space environment, the magnetosphere, as a natural laboratory to directly measure reconnection. Reconnection is a common processes in our universe; occurring in space near Earth, in the atmosphere of the sun and other stars, in the vicinity of black holes and neutron stars, and at virtually any boundary between space plasmas, including the boundary between our solar system's heliosphere and interstellar space.

Solar Storm Forecast 02-19-2015 with Dr. Tamitha Skov, #SpaceWeatherWoman. And check out http://spaceweather.tv/

The Sun has quieted down this week with no major flares since February 10 and only a few weak active regions in Earth view. This quiet should persist for the next few days until some activity rotating onto the East limb comes more into view. This will be a relief to GPS and amateur radio operators as no disruptions are in sight. We did reach solar storm levels for a brief period on February 17-18 due to a combination of a grazing solar storm passage and a high speed wind stream. These effects brought aurora to many regions around the globe, but they will be waning over the next 24 hours. Learn what the Sun has been up to, catch up on some recent aurora activity and see how you might be affected this week.

Большое спасибо за информацию о солнечной активности!
Активность сегодняшнего солнца сильно влияет на людей - начались войны , которые перерастут в глобальную войну на самоуничтожение и разрушение мира!

The sun let off an M2.4 (or mid-level) solar flare that peaked in X-rays (measured from GOES satellite) at 23:35 UT or 6:35 EST. The flare producing eruption came from sunspot group or active region 12282. This region has only recently rotated into view. Here is a short video of the event using 3 wavelengths of extreme ultraviolet light (171, 193 and 131 angstroms.) The eruption also produced a beautiful CME that headed off to the left of the sun so is not Earth-directed.

Wow, that is a lot of images - 100 million images and counting!!!

On Monday, January 19, 2015, around 17:50 UT, AIA took its 100-millionth on-orbit image of the Sun (and its basic 'level-0' data archive will then exceed 100 billion MB)!!!

The Atmospheric Imaging Assembly (AIA) is a prime instrument on NASA's NASA Solar Dynamics Observatory (Little SDO) (launched on February 11, 2010; observing the Sun in science mode since May 1, 2010). AIA takes one 16-megapixel image of the Sun's atmosphere every 1.5 seconds, adding (with the other instruments, HMI and EVE) well over a petabyte of data to the mission archive each year. 

It is a unique instrument, observing everything in the solar atmosphere, all the time (with interruptions only when calibrations need to be taken or when Earth or Moon briefly obstruct AIA's view). The results are streams of images, movies, scientific studies, and media attention.

Colorful complement: AIA images the Sun in 10 different channels (as here on 21 October 2010), going from the solar surface (in 'white light') to the extreme ultraviolet emitted by the transparent corona (from 171A to 131A, covering temperatures from some 5700 K to over ten million K.

Angstroms? Why not just use nanometres?

T - 8 days until the launch of NASA's MMS (Magnetospheric Multiscale)​ mission.

MMS will travel through two known areas of reconnection near Earth: on the dayside where magnetic fields from the sun connect to Earth’s fields and on the night side where Earth’s own fields can reconnect with each other.

Aurora and Ice - an stream of fast solar wind brought us some geomagnetic activity along with aurora. 

"Simply wow!
Spectacular aurora night here in photographers paradise - Iceland ! I got so many wonderful shots from different locations during one night that its bit overwhelming! It was difficult to choose where to go to take the pics from, let alone to choose where to point the camera! I took my first photos around 22:00UTC and headed back home around 02:00UTC and the show is still on outside as I write this, but I have to get sleep for tomorrow is another early working day here guiding at the glacier and ice caves."  by Mika-Pekka Markkanen on February 28, 2015 in Iceland

The eruption from yesterday (associated with the M2.4 flare) produced a CME (coronal mass ejection) that showed up very nicely in the SOHO/LASCO coronagraph C2. A coronagraph creates an artificial eclipse by blocking out the bright solar disk allowing us to observe the faint CME (as compared to the solar disk), as it flies away from the sun at many millions of miles per hour (km per hour.) credit: ESA/NASA/SOHO

And here it is - SDO/AIA's 100 millionth image of the sun!!

The Advanced Imaging Assembly on NASA's Solar Dynamics Observatory captured its 100 millionth image of the sun on Jan. 19, 2015. The image shows the glow in the solar atmosphere of gases at about 1.5 million Kelvin.

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!
