Publication Alert!
Check out this publication on the development of a global gridded dataset from irrigated and rainfed cropped area from 2000 to 2015 for 23 crop classes by our member Stefan Siebert. Congratulations on the work!

Gif sequence from stills, static camera in rotating Earth frame.
Lunar eclipse 2025-09-07, end of Earth's shadow moving off disk.

This is exactly why my multiexposure of the eclipse last night still had an overlap — since I had completely neglected lunar motion around Earth in a 128 sec gap estimate. Mun moves on orbit 3% the length of its body-dia in the meantime. Andrew's pic is brilliant, just wonder why shadow static(?)

Or /iow: waiting longer btw the Moon shots makes the disk 'move' further to the up right b/c camera on Earth has rotated further (24h/day), but at the same time the Mun also had a slight shift to the left on its 28d-journey around Earth. Hence, relative rotation appears 3-4% slower than 2π/24h. 2/2

Nerd-fact: I had roughly estimated from lunar diameter, distance, +Earth rotation that 130s would be just enough to get clear lunar 'disks':
128s=atan(dia/dist)/(2π/24h).
But I neglected lunar counter rotation around Earth, which adds a few seconds to the bill. That's why the disks overlap a bit 1/2

Lunar eclipse tonight, S of Bonn, Germany. Best part was to see how many parents with children came out and patiently waited to observe!

Cooking with 15" etopo22 and @wmo-global.bsky.social / GRDC vectors for @crc1502-detect.bsky.social . Rivers truly are lifelines of the water cycle.

Critical mission milestone achieved for this one, 12m reflector unfurled:

So you are saying the enforced d(TWS)/dt — instead of ET + Q — temporarily balances a grand part of the P? 🤭
(rather runoff/surface flow than Q...)

Good job.

Officially yes :-|
But I can still load projects 🤷

What to do when trains don't go to the DETECT retreat? Cycle! 35 km through the beautiful Rhine valley.

Do the groundtracks include model dynamics, d(mean anomaly)/dt, or are they based on the latest TLE? (Rhetorical Q: would we see the difference on such a map?)
