Here's my guide on how to make storm-following loops using GR2Analyst and a (free) app called ScreenToGif! docs.google.com/document/d/1... 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!

Spent some time reprocessing my Orion (and more) photo from last year today! Lots of stuff to look at

My arguably questionable CME run with HUXt for the filament launch the other day. I get arrival @ 0319z on 2026-08-17. We'll see how I do!

First go at analyzing the earlier CME. I may have been a little generous on the width measurement in my software, but I don't think TOO generous. Gives me this outcome: Earth hit: yes, arrival=2026-08-08 17:49Z We'll see? It might suck (both my analysis and the CME)

Bonkers CME came from AR14436 a little bit ago. Look at that insane blast wave! Ridiculous amount of material probably got yeeted into oblivion

Probably my favorite lightning photo I've ever taken. I've never seen a picture like this where there's a horizontal bolt glowing just above the clouds like this!

Some lightning shots from last night near Strong City, KS.

One of my favorite shots from last night near Strong City, KS. Best mammatus photo I've ever gotten!

Remembering 2025/11/11 and wishing I could see it again

Animation of sunspot group 4366: rapid growth – in 36 hours from almost nothing to a complex mess.

How y'all doing in the big 2026 so far?

Looking for opinions on my plots here -- do dashed lines (for 5, 10, 15, 20 solar radii) look/work better or do solid rings do? The dashes are slightly thicker as well, but only just. Trying to figure out which version to plot on my website

the worst part of owning cats is when they leave a massive hole in your heart when they leave

This is actually insane! It looks like a hellish demon trying to escape the sun!

Map showing the coldest season of the year.

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 :(

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

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!
