After a 1yr pause, we are happy to announce that the iGrav043 of the IGG @jurgenkusche.bsky.social @unibonn.bsky.social is back in the 4K superconducting game! Up and running smoothly. Our team is performing some fine tuning over the next days and hopefully still fetch a glimpse of the #2026draught

I made a 51k ride this morning, /w temperature profiling in mind. ➡️ Relative #Cooling effect of the Kottenforst woods near #Bonn (here at ~40–46 km): >5 Kelvin! (blue line). At 39km: asphalt-rich settlement; 48km: mixed village; 50km: suburbs /w lots of green. Backfill: altitude range 200m
An overlay showing altitude and temperature plotted over cycling distance. The temp curve shows notable local peaks and lows that can be associated with hot asphalt rich settlements and cooler woodland segments during the ride

🦋PhD work "Multiannual Reconstruction of the Butterfly Effect" 😉 We observe a clear trend in opacity, which might be an early indicator for the human impact on kitchen climate. Formed over 3yrs during lunch times +colleague with hunger for Marzipan (wasn't me I swear!).

Lunar eclipse tonight, S of Bonn, Germany. Best part was to see how many parents with children came out and patiently waited to observe! [Pentax K1, in-cam multiexposure every 2m10sec]

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

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