THE SUN TODAY: The Sun suddenly came alive! 1) SSN up to 140. 2) 5 M flares from 3 different sunspot regions. 26 C flares! 3) Two regions coming over E limb. 4) substantial growth in several regions while three significant new spot regions on the east limb. 5) 12 CMEs yesterday.

Sun continues being very active.

No GSM now and no mini ice age now. Then again, even if the sun was in a GSM there would not be a mini ice age caused by that, just some slowdown in the rate of warming for under one decade. All the weather reports of snow and cold posted in what is supposed to be the Environment MRB do not paint a picture of a mini ice age. LOL!

What happens on the sun matters to the critters on Earth and any in space.

The sun has already become so active that a Grand Solar Minimum now is ruled out. This means that once the La Nina conditions end and become ENSO neutral we can expect more high temperatures—2022 could become the hottest year so far. That is even without El Nino conditions.

THE SUN IS GOING CRAZY! Four M flares today - 3 in the last 6 hours. The X-ray background has nearly risen to the M Flare level. We should expect some moderate to large M flares in the next day or two, perhaps even an X flare. Fingers crossed. Nothing to panic about.

FIND THE FLARES: Flares appear as short-lived flashes in the bright active regions. It might be easier to find which regions are not flaring.

Wow! A whole new observatory reveals new activity on the sun!

CLOUDS FORM HIGH IN SOLAR ATMOSPHERE: These are not clouds as we know them (H2O) but clouds of cool plasma (50,000K). Coronal loops at over 1 MK lose their source of heat and condense down to lower temperatures and appear in this channel. They then drain down to the Sun's surface

It looks like a huge, evil spider on the east limb of the Sun, but of course, it isn't. It is a dynamic complex of magnetic loops interacting with each other until they eventually erupt. This the same region that has produced some of the series of M flares over the last two days.

THE SUN TODAY: 1) SSN still at 140. 2) Seven M flares in last 24 hours. 3) Substantial region behind the NE limb according to STEREO. 4) The M flares came from two sunspot regions - AR3213 and AR3217 (on the SE limb). More, large spot appearing on E limb. 5) Just 3 CMEs yesterday

This series of tweets by Dr K. Strong is absolutely fascinating. You see the sun as if we are just floating above it. Flares, spots, CMEs, plasma “cooling” to “just” 50,000°K (LOL!) all shown for our information.

I will keep this thread going until the sun winds down to the next solar minimum. (and maybe after, if the two observatories have interesting data on that phase of the suncycle.)

The sun provides 99.9% of the energy at the surface of the earth so is of vital importance to the critters on this planet!

To illustrate:

Quote:
A VIOLENT ERUPTION FROM THE EAST LIMB: Active region AR3217 just produced a spectacular eruption. It almost certainly produced a coronal mass ejection but fortunately for us it is too far east to affect the Earth. Note the plasma falling back the Sun is pushed away by an outflow.

THE SUN TODAY: 1) SSN up 175. 2) Five more M flares in the last day plus a host of high C flares. 3) Still more to come over the NE limb. 4) The M flares are from 3 different areas - one of which was spotless! 5) 6 CMEs yesterday.

THE WEATHER IS ABOUT TO CHANGE: This plot shows the NOAA probabilities for La Nina / ENSO Neutral / El Nino conditions in the Pacific. It predicts that in March the most likely condition will be ENSO neutral. That will persist until the Autumn when we will swap over to an El Nino

Do we get colder weather in winter during El Nino?

Update: Bureau of meteorology states that less cloud cover means colder conditions. Especially for eastern Australia.

THE SUN TODAY: 1) SSN up to 185. 2) We have had eight M flares in the last day. 3) Yet more regions over the NE limb (dashed white line). 4) The M flares came from four different regions. Will we get an X flare? Lots of small spots emerging but die quickly. 5) Ten CMEs yesterday.



This is not a quiet sun, this is not a sun in a GSM.

EVERYTHING Booby has posted in his toilet of a board is a lie.

CME WATCH - 2023.02.11: Lots of action today, too much to comment on individually! Just the bigger ones: 1) large diffuse off the SW limb. 2) Bright CME off N. Pole. 3) Bright, narrow event off SW limb simultaneous the faint one off NE limb. 4. Very large, diffuse one off W. Limb

What is an XFlare?

Quote:
X flares are the most powerful category of flares, and can cause geomagnetic storms to affect Earth's magnetic field with the potential to damage satellites, communications equipment and even the power grid. The flare was the most powerful seen since at least October. NASA/SDO An X1 flare like this one, though, is at the low end of the X-scale.
