stressed about chem exams so I did a ghost king doodle to cope

#I like the nonconventional crown designs tbh #the stars here are the Corona Australis and Corona Borealis #and ofc I had to throw in some northern lights #bc ice powers duh #I'd probably have added more constellations but I got lazy #there's a few that feel thematically appropriate #like the balance the microscope the hunter the chameleon #to name a few #danny phantom #danny phantom fanart #danny fenton #ghost king danny #ghost king au #pax art #pax doodles

Today's auroral shenanigans

Relatively speaking, yesterday night (May 11/12) was a bit of "not much" for aurora-watchers, compared to the night of the 10th/11th. (Which, to be fair, was a most unusual event, and it wouldn't be surprising if it wasn't equaled for a long, long time.)

Nonetheless, the Sun continues to be in an interesting mood at the moment... specifically the big sunspot region AR3664, which is the one responsible for the auroral extravaganza of May 10th. You can just see it in this next image, getting ready to rotate away from us around the Sun's rightward limb.

(For those interested in scale: that complex of sunspots is about fifteen times the diameter of the Earth. You could drop the whole planet into the middle of the biggest one and lose it. A timelapse video of its growth is over here at YouTube, if you're interested.)

As AR3664 continues to spit out CMEs and flares, the NOAA has issued a geomagnetic storm watch for today, tonight and tomorrow—with the suggestion that conditions like those of the night of the 10th may in the relatively short term be about to repeat themselves.

This is a "watch" rather than a "warning," reflecting some uncertainty over exactly how the various incoming coronal mass injections are likely to behave on reaching Earth orbit. (Also, the CMEs aren't being aimed straight at us, but off to one side as the sunspot region rotates further and further toward the sun's edge: so this adds somewhat to the unpredictability of it all.)

The animation below comes from the SOHO spacecraft's LASCO C3 coronagraph instrument. It starts on May 10th and runs through until early on the morning of May 12th. You can see the newest incoming CMEs right at the end of it.

(BTW, I think the two bright objects to right and left of the Sun are probably comets passing through, as LASCO images normally mask out any planets that would be in view.)

Anyway, as for what this means for auroral activity tonight? It's tough to tell as yet. The planetary K index (which expresses the relative strength of geomagnetic storms) has dropped back down into near-baseline levels at the moment.

But when those new CMEs and the solar wind associated with them hits the atmosphere, things may change suddenly.

We'll soon see...

And an afterthought: AR3664 will soon be off around the Sun's edge, and invisible to us. It'll be interesting to see what happens to it after that.

The Sun takes 27 days to rotate, as a whole: the poles take longer, the equatorial regions a shorter time. In a couple of weeks or less, what will greet us, rotating around toward Earth's POV on that left-hand side? Will AR3664 have dissolved and vanished away, as sunspot groups so often do... or grown even bigger?

ETA 1, 12 May 2024, 1820 UT: Like a kitty coughing up hairball after cosmic hairball, AR has popped yet another X-class flare.

ETA 2, May 13 2024, 0100 IDT / 0000 UT: New G3 storm warning dropped.

You might know about wombats, but what about numbats (Myrmecobius fasciatus)? These Australian marsupials are picky eaters with a taste for termites. Using their long tongues, these specialists can slurp down 20,000 of the insects in a single day! Unlike many mammals, the numbat’s mouth is filled with dull, peg-like teeth. But that doesn’t stop this critter, because it doesn’t chew its food anyway.

For all my gorgeous northern friends, I present: Aurora Australis!

Pics by me, taken off my lawn and down the road on the beach where we had to make sure there weren't sleeping seals before we set up. No filter, no photoshop, just straight from gods brain to your mouth. Enjoy!
