Here's my guide on how to make storm-following loops using GR2Analyst and a (free) app called ScreenToGif!

This can be adapted for other radar software but the storm-following is a feature of GR2A. You'll have to manually do it if you want it without GR2A!

Ended up getting this working quite a bit better! Here's a few more:
4294 + 4296,
3664,
4294 + 4292,
4290 + 4291
Surprised it's doing a pretty good job of picking up only umbra/penumbra! Not perfect but better than I expected!

Bored today so I put some time into building an automated sunspot detection/measurement script. Not perfect but does a decent job I think! Also really, really nice to be able to overlay it on magnetometer data like that.

An absolutely tremendous active region has rotated into view over the past few days. It is huuuuuuuuge! Very excited to see what sort of geomagnetic incidents this thing sends our way in the next two weeks or so.
Can't forget former 4274 peeking around the NE too! Two intense solar regions at once!

Been having fun watching SDO imagery today... lots and lots of action on the limb!

From 4/27/2011, a short multi-tilt storm-following loop from ARMOR of the Hackleburg tornado. Some pretty incredible temporal resolution is possible like this when you interleave the different tilts! You get some shakiness but overall this turned out quite incredible. Love the merger stream!

Also a short time lapse video of the proton aurora being extraordinarily bright and dynamic!

Anyone else get absolutely dazzled by the ridiculous amount of proton aurora on 11/11? All night it was showing up in very quick bursts!

Cannot get over how magical and surreal this picture looks. A very sharp contrasting line between the incredible auroral crimson and the black night sky. This was taken looking west around 10:49 PM from central MO.

Goodbye Banzai, my friend, best buddy, and family member of the past 14ish years. Huge hole left in my heart right now :(

Probably my favorite aurora photo from 11/12.

Finally got around to skimming through my DSLR pics! The first one with the crazy proton aurora is actually the very first DSLR photo I took of the night. Absolutely insane to have captured this collection of photos from Missouri!

Some of my favorite shots from 11/11, taken from east central MO. Some of these from my front yard. Going to be pretty hard to ever see a better aurora event from my house than this one! The colors were insane, and everything was so excessively naked-eye visible!

The greatest atmospheric ballet! Large, highly visible snow mesovortices rolling down a convergence band over Lake Michigan on 2024/01/19. Perhaps the most beautiful radar data NEXRAD has ever produced. This is a 14 hour loop showing the ridiculously high number of them that developed sequentially

@twisterkid34.bsky.social Just curious, with the new paper in WAF, do you now have a storm event DB with mode classifications/metadata that is requestable? Sure would be incredibly useful for some projects I want to work on (though unfunded personal projects analyzing existing data in newish ways)

Storm-following, multi-tilt, multi-radar loop of the tornado event from 2015/05/06, as seen by KTLX and ROP4 (KCRI). Spliced-together loops like this give us a pretty incredible look at the motions going on that often gets lost between sweeps!

Storm-following (vortex-following where possible) loop of the Duke, OK tornado from 2024/05/23! Including its beautiful development from a huge hook echo and subsequent dramatic occlusion through the precip core. Used tilts 0.5°/0.9° for this one, 1.3°+ made it worse.

Another python-generated storm-following loop, this time 6 hours of the Mayfield supercell from 2021/12/10! Imperfect, dealiasing wasn't amazing, and the plot format needs some decrapulating but overall happy with it! Surprised the motion vectors kept it so centered!

4-Radar Multi-Tilt Storm-Following loop of the 2013/05/20 Moore, OK Tornado. Splicing together multiple radars gives us some pretty crazy temporal resolution, even if it's a bit... spazzy. Been having fun with my new script!
bsky might mangle the quality of this video, so apologies in advance!

Some storm-following loops from 2012/03/02, plotted by my python script utilizing multiple tilts to get slightly more temporal resolution!

A couple of shots of Lemmon from tonight! Trying to figure out what sorta edit I like best. Feels like I was pretty wildly successful with my photo shoot though! <3

So I tried my first shots of some nebula (well technically second, but I completely missed my first attempt) this morning, and this is what came from the stack. Was very much not prepared. Still some processing to be done but damn I am excited I even got this far!

Appears to have been a couple tremendously weak tornadoes near Cannel City, KY 20 or so minutes ago! Pretty clear TDS's, although low reflectivity and low velocity makes me think these are probably non-damaging tornadoes picking up leaves and stuff. Still worth watching out for more!

Some good hail in that storm near Tulsa! A pretty impressive hail spike combined with azimuthal side lobe seems to indicate there's either big hail, a lot of hail, or both! Seems that right now ~1" hail has been dropping.
