nope .. should be another 2 inc the best one ...

Indeed Flea, must admit I'm learning alot atm as interest is piqued.

A fast CME will take 15 hrs to travel to earth, slower ones will take 2 days or more.

Hence the idea of the cannibal CME this weekend where a couple of slower ones got caught up by a faster one. I believe this is what shot the levels to G5.




Sadly there are no sensors to detect the progress of CME towards earth. Stereo A is currently near earth as it orbits slightly closer to the the sun, hence some information could be gained, but its position is a coincidence relative to the events this weekend.

Stereo B lost power in 2016 which was a loss for farside imagery.

There are more CME incoming over next 24+ hrs. We are very much blind as to any details and can only really see how things develop in real time.

Meanwhile, the very active region associated with 3638 is rotating back earthside, currently appears to have decayed.

Fortunately (?!) Glancing blow at best....

Frigging CO2!

2 more X-class flares, AR3664 firing an X3.4 over its shoulder and a new region behind the east limb has just tripped and banged its nose on the doormat with an X2.99

SC25 is still looking very much like SC13,

Solar cycle 13 was the thirteenth solar cycle since 1755, when extensive recording of solar sunspot activity began.[1][2] The solar cycle lasted 11.8 years, beginning in March 1890 and ending in January 1902. The maximum smoothed sunspot number observed during the solar cycle was 146.5 (January 1894), and the starting minimum was 8.3.[3] During the minimum transit from solar cycle 13 to 14, there were a total of 934 days with no sunspots.[4][5][6]

There were a number of intense solar proton events during solar cycle 13,[7] as well as geomagnetic storms such as in September 1898 which affected telegraph lines.[8]

See the explosive 'devil comet' get its tail ripped off by a solar storm days before its close approach to the sun

A surprise coronal mass ejection recently smashed into Comet 12P/Pons-Brooks, briefly causing the "devil comet" to lose its tail — and a NASA spacecraft caught the whole thing on camera.

The explosive "devil comet" has been blasted by a gigantic plasma wave from the sun, which temporarily blew away its dusty tail. A NASA spacecraft captured the epic encounter in a new video, which also features a cameo of a distant Jupiter.

Comet 12P/Pons-Brooks (12P) is a green cryovolcanic comet with a nucleus measuring 10.5 miles (17 kilometers) across. It occasionally erupts, shooting an icy mixture of gas and dust into the solar system whenever it soaks up too much of the sun's radiation. When this happens, its coma — the cloud of particulates that surrounds the nucleus — expands and becomes much brighter. In the past, this bright cloud has been misshaped from within, giving the comet a "pair of horns" that earned it its sinister nickname. However, these horns have been absent from recent outbursts.

12P orbits the sun once roughly every 71 years on a highly elliptical, or stretched, trajectory. As a result, the comet spends most of its life in the outer reaches of our cosmic neighborhood, out of sight from our telescopes. However, it is currently making its last dash toward the sun and will reach its closest point to our home star, known as perihelion, on Sunday (April 21). It will then slingshot around our home star and back out toward the edge of the solar system — if it isn't first burned up by the close encounter.

On April 12, the comet was bashed by a massive cloud of plasma known as a coronal mass ejection (CME) that exploded from the sun without warning, Spaceweather.com reported.

The incident likely triggered a disconnection event, in which the comet's dusty tail was temporarily blown away by the solar storm, video footage captured by NASA's Solar Terrestrial Relations Observatory A (STEREO-A) spacecraft shows. In the new footage, 12P also appears to be moving close to Jupiter (even though the two bodies are millions of miles apart).

Photos from April 9 also show a kink in the comet's tail, was likely caused by another previous disconnection event, Live Science's sister site Space.com reported.

Etc ...

So as I continue my trip down "solar max is unlikely to have been last year" lane.

The active area that produced some of the most widespread aurora borealis for many generations, is about to rotate earthside again.

It produced another massive cme while farside.

For the record....observing northern lights from my garden was a very nice way to be wrong 😉
