Magnetic field lines - July 23-24, 2012



Magnetic field lines between two active regions extended across about one-third of the Sun to make their connections (July 23-24, 2012). The magnetically powerful active regions were just rotating into view, giving us a wonderful profile of their activity. The lower active region also spurts out several bursts of plasma as well. The looping arcs above each active region shows off the field lines nicely too.

M6-CLASS FLARE July 28, 2012 20:56 UT Time



M6-CLASS FLARE: Solar activity is picking up. For the second day in a row, sunspot AR1532 has unleashed a moderately-strong solar flare. The latest, an M6-class eruption, occurred on July 28th at 2056 UT. NASA's Solar Dynamics Observatory captured the extreme UV flash.

It is too soon to say if the eruption produced a coronal mass ejection (CME). If it did, Earth would likely receive no more than a glancing blow from the cloud. The sunspot is too far off disk center to be very geoeffective. This could change in the days ahead, however, as the sunspot turns toward Earth.

Thank you IndianaBoys .... as usual always a pleasure reading your posts

MonsieurM and Wizofid,

Admiring the beauty and connecting with the level of conscious that stands behind all of creation is truly an amazing experience that is available to all.

Thanks for acknowledging your interest and sharing in this.

M-class Flare July 27, 2012 Time = 1726 UT



M-CLASS FLARE: Newly-emerging sunspot AR1532 unleashed an M2.7-class solar flare on July 27th at approximately 1726 UT. NASA's Solar Dynamics Observatory captured the extreme ultraviolet flash.

The explosion does not appear to have produced a substantial CME (Coronal Mass Ejection). Even if it did, Earth is not in the line of fire. This sunspot will, however, become more geoeffective in the days ahead as it slowly turns toward Earth. Stay tuned for updates.

MM - I have to agree -

IB - Thank YOU so much for you attention to this. My sweetheart and I for the past couple of years have been looking at some of the pictures and once in a while copying them onto our harddrive. I find them to be natures expression of what is going on the the magnetic and electric world. It is about paying attention to these systems.

Sadly - many never see the beauty or are even curious to look.

Cheers

Magnetic Bridge



MAGNETIC BRIDGE: Sunspots AR1528 and AR1529 appear to be far apart. More than 200,000 km of stellar surface separate the two. Nevertheless, they are connected by a tubular bridge of magnetism. NASA's Solar Dynamics Observatory (SDO) photographed the vast structure on July 24th.

This extreme ultraviolet image traces the bridge via the glow of hot plasma it contains. Material can flow back and forth inside the tube, allowing one sunspot to respond to what the other is doing.

Researchers once thought that sunspots were independent operators, but SDO has shown over and over again that widely-spaced sunspots can be linked. An eruption in one can set off an explosion in another, leading to a chain reaction that can spread around the circumference of the sun.

Very Fast Farside Cme:



VERY FAST FARSIDE CME:

A coronal mass ejection (CME) blasted away from the sun this morning with rare speed: 2930 km/s or 6.5 million mph. CMEs moving this fast occur only once every ~5 to 10 years. The Solar and Heliospheric Observatory recorded the cloud's emergence on July 23rd starting around 0300 UT.

The source of the CME was sunspot AR1520, which sparked many bright auroras earlier this montth when it was on the Earthside of the sun. Now, however, the active region is transiting the sun's farside so this blast was not geoeffective. One can only imagine the geomagnetic storms such a fast CME could produce if it were heading our way.

Sunspot emerges over the sun's southeastern limb. July 22, 2012



July 22, 2012 AROUND THE BEND? The Earth-facing side of the sun is mostly blank and quiet. This could change in the days ahead as a new sunspot emerges over the sun's southeastern limb. NASA's Solar Dynamics Observatory can see the active region's magnetic canopy, which is towering over the limb in advance of the sunspot itself.

The core of the active region should show itself no later than Tuesday. Meanwhile, solar activity is low. NOAA forecasters estimate a mere 1% chance of M- or X-class solar flares.

CORONAL HOLE July 21, 2012



CORONAL HOLE: A vast dark gap in the sun's atmosphere--a.k.a. a "coronal hole" --is rotating onto the Earthside of the sun. NASA's Solar Dynamics Observatory photographed the emerging structure on July 21st:

Coronal holes are places where the sun's magnetic field opens up and allows the sun's atmosphere to boil away. The escaping gas forms a stream of solar wind. This coronal hole is perfectly positioned near the sun's equator to create a geoeffective stream--in other words, the solar wind stream will hit Earth directly. ETA: July 27 or 28. High latitude sky watchers should be alert for auroras on those dates.

Corona - Total Solar Eclipse

One of the most spectacular sights in all of nature is the corona during a total solar eclipse. The corona is the sun's atmosphere. It actually extends far out into the solar system, well past the Earth.
