Hex Mayflies
Hexagenia limbata
The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.

This is an interesting one. Following the keys in Merritt R.W., Cummins, K.W., and Berg, M.B. (2019) and Jacobus et al. (2014), it keys clearly to Ephemerella. Jacobus et al provide a key to species, but some of the characteristics are tricky to interpret without illustrations. If I didn't make any mistakes, this one keys to Ephemerella mucronata, which has not previously been reported any closer to here than Montana and Alberta. The main character seems to fit well: "Abdominal terga with prominent, paired, subparallel, spiculate ridges." Several illustrations or descriptions of this holarctic species from the US and Europe seem to match, including the body length, tarsal claws and denticles, labial palp, and gill shapes. These sources include including Richard Allen's original description of this species in North America under the now-defunct name E. moffatae in Allen RK (1977) and the figures in this description of the species in Italy.

Well, this isn't a fishing post, but when all the fish are under four feet of ice and snow, we have to look elsewhere for entertainment. Elsewhere... like up.
Intense sunspot activity for the last week or so has painted faint bands of aurora across the sky in Fairbanks pretty much every recent night that we could see them through the clouds. Mostly, these slow-moving pale green stripes aren't anything to get excited about in Fairbanks. Last night, we finally had the right combination of a clear sky and a more intense aurora, and I had my camera out on the deck at the right time.
The display was pretty good for half an hour or so, but the most intense activity lasted just a couple minutes. Green and red waves swirled rapidly overhead like someone was mixing them with an eggbeater. I didn't catch that on camera, but I did catch some of the shimmering green waves that followed. After the most impressive action, I went back to work and enjoyed the diffuse green glow out my window.

That is very cool! Much better than the sky in Michigan last evening I bet!

Very cool.

I'm totally jealous! As far as I can tell, nobody has been seeing them around here (that I've heard of anyway), a surprise given the massive solar storms as of late. Night skies have been pretty nice, however, with the winter constellations and Venus, Mars, and Jupiter.
Send some our way!!!

No matter how big the one you just caught is, there's always a bigger one out there somewhere...

Golly! those are gorgeous!
i guess i can forgive the solar storms for what they did to my new laptop...just shut down and refused to start again and the shop never did figure out why. i'm blaming the sunspots!

Nice shots Jason,
I saw they were out last night, but I went to bed early so I missed most of it.
By the way what forecast sight do you use? I use http://www.gi.alaska.edu/AuroraForecast. This is also another good site for those of you who can't be here http://salmon.nict.go.jp/live/aurora_cam/live_aurora_cam_e.html.
I'll be looking out again tonight.

Sam, here's the main forecast I use:

I also check the sites you linked, especially the live camera. Also,

Very cool, Jason. We had the lights here a few months ago, but it seems like I only find out about these things too late. I'd love to see them sometime.

Wonderful stuff Jason! And here I thought you were off the grid up there...Instead you appear better connected than most of us...:) That's quite the set up.
My favorite northern lights sighting was in 1973. My best friend and I were actually trying to get home from Alaska, had flown to Seattle, and tried to hitch-hike cross-country. We were somewhere between Coeur-d'Alene and Bozeman, it was after dark and we were riding on some stacked hay-bales in the back of someone's pickup.
The guys in the truck didn't want to leave us out in the middle of Montana at night and had offered to put us up...We decided to make a go of it and continue...I remember one guy saying, "Fellas. It can get pretty cold at night, here in Montana, in late May...Are you sure?!"
We survived. :)
Good stuff Jason! Thanks for showing it to us...Like others here I had heard that we should be seeing something down this way but never did.

Somebody I know just went up to Arctic Village and she said that they have Internet and video games. Here I thought THEY were off the grid.
