Work in progress. Artist's expecting to finish the whole mural by the end of the week, despite the winds interfering. More: https://www.svt.se/nyheter/lokalt/vasternorrland/jattebaver-pryder-nya-parkeringshuset-i-sundsvall #onlookerOnTour

@michael_w_busch @CStamp @sundogplanets there's a flare at around 7 o'clock (apparent N Africa/Mediterranean) with a non-flaring companion a bit to the left. Looks like they are on a polar orbit, so I thought they could be Kosmos stages, those are the brightest most usual satellite sights one could have at our northern latitudes not so long ago... There may be a meteorite cameo over the sea as well.

@carolynporco the discord link above is where I got it from. fredk is an avid image processor but I'm not aware if they have a main account for posting (maybe @PaulHammond51 or @pomarede know?). The source photos are in the public domain & I bet there'll be more processing by others ( @stim3on ?) since there appears to be more exposures, only of varying quality (the lighting conditions are challenging but so gorgeous...)

@michael_w_busch @sundogplanets it's more visible on a larger screen and with more brightness. I'll see if I can do a crop

The "Hello World" photo from #ArtemisII did not come alone. Here's an animation put together by fredk of multiple exposures (UMSF After Party https://discord.com/channels/1290524907624464394/1305654861496451182) showing a receding Earth in moonshine.

Crank up the brightness and behold lightning in Africa & South America, shifting aurorae at the poles... & satellite glints all over the place, most visible at 3 & 9 o'clock 🤯

I remember ppl suggesting using stuff like this to do SETI...

TL;DR: in situ carbonation of olivine is the preferred formation method for the #JezeroCrater carbonates detected by #PerseveranceRover along its trek.

@floe@hci.social @jovi@hci.social as a sw eng with an enthusiast's interest in orbital dynamics packages & viz, specially REBOUND which I've toyed with many times, this paper was a swift read. I don't know what kind of reviewer you're looking for, but let me know if I can help
