2015..

Here’s what the first big solar flare of 2015 looked like

The sun was relatively quiet at the end of 2014, at least in comparison to some of the powerful solar storms seen earlier in the year. But it only took a couple of weeks of 2015 for the star to send out some crazy streams of radiation. These images from NASA's Solar Dynamics Observatory record the sun's peak activity at 11:24 p.m. Eastern time Monday.

Sun Emits Significant Solar Flare

The sun emitted a significant solar flare, peaking at 12:22 p.m. EDT on March 11, 2015. NASA’s Solar Dynamics Observatory, which watches the sun constantly, captured an image of the event. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel.

From Space.com:
The sun brings gives light and warmth to all life on Earth, but it has a temper too. Solar flares, eruptions and other sun storms can have serious effects to satellites and other systems around or on Earth.

Severe solar storm bathes northern skies in dazzling green auroras


A severe geomagnetic storm whipped through Earth’s magnetosphere on Tuesday, causing fluctuations on power grids and spawning a beautiful green, St. Patrick’s Day-themed aurora that stretched from the Arctic Circle to as far south as Oregon and Illinois.


The storm, which began late Monday, is among the strongest in the current 11-year solar cycle, earning a rating of a “severe” G4 on a one to five scale, which means it had the potential to affect power grids, high-frequency communications and satellite operations.

I received from my Higgs Boson course of Edinburgh University the notion that the Higgs Boson causes the Sun to burn slowly and give us a temperate climate. So we should be grateful to the Higgs Boson.

I would like to hear more about that. Are you willing to go into more detail, or is it all forgotten?

The things I remember from my studies (and I have forgotten so much) is that it takes about a 1000 years for a photon to get out of the sun. I remember the P-P chain for hydrogen to helium fusion. I remember doing some calculations on potential to kinetic energy to show how stars start to burn....and I vaguely remember something about coupled neutrino oscillations showing how one type of neutrino turns into another. These are obviously the more interesting facts that stuck in my head.

It was said by a lady in a short video at the end of the course. I would have welcomed a more detailed information but that was all.

According to an article published on "Science" magazine the mass difference between the proton and the neutron, which is heavier by 0.14% is the optimal one for a Finely Tuned Universe, which allows for the appearance of life forms.This reminds me of the GAIA hypothesis.

Or rather what I like to call the "Amen" conjecture:

We are here and exist precisely because the physics of our universe contrives to provide the mechanisms and conditions required for our existence.

Bright Filament Eruption

Pictures and Video available at above link.

An elongated solar filament that extended almost half the sun's visible hemisphere erupted into space on April 28-29, 2015, in a large burst of bright plasma. Filaments are unstable strands of solar material suspended above the sun by magnetic forces. Solar astronomers around the world had their eyes on this unusually large filament and kept track as it erupted. Both of the coronagraph instruments on the joint ESA/NASA Solar and Heliospheric Observatory, or SOHO, show the coronal mass ejection associated with the eruption.

The top image was taken by SOHO's LASCO C2 coronagraph and the bottom by LASCO C3.

LASCO, which stands for Large Angle Spectrometric Coronagraph, is able to take images of the solar corona by blocking the light coming directly from the Sun with an occulter disk, creating an artificial eclipse within the instrument itself. C2 images show the inner solar corona up to 8.4 million kilometers (5.25 million miles) away from the Sun. C3 images have a larger field of view: They encompass 32 diameters of the Sun. To put this in perspective, the diameter of the images is 45 million kilometers (about 30 million miles) at the distance of the Sun, or half of the diameter of the orbit of Mercury. The white circle in the center of the round disk represents the size of the sun, which is being blocked by the telescope in order to see the fainter material around it.

As I drove home from work yesterday, the Sun was right in front of me in the sky. Just looking at it (with sunglasses of course) gives a person so much energy!

There is also a scientific reason apart from an emotive one.

Vitamin D is essential for healthy bones, and everyone needs vitamin D to absorb calcium and phosphorus from their diet. Our body creates most of our vitamin D from direct sunlight on our skin. We also get vitamin D from some foods – including eggs, meat and oily fish such as salmon, mackerel and sardines.

NOT through an UV glass in a car!
& our body doesn't create anything under sunlight - it TRANSFORMS a provitamin into vitamin...

btw, Julie...don't look @ the sun, unless u have a welding equipment or special astronomy eqiupment for a star gazing! ;)
