Very glad to see our joint paper on smart tariffs and services in Europe now published!

What do these tariffs do, where are they emerging and what inputs do they use to optimise EV charging, heating and other household loads?

The roads to get to the starting point of this hike are an adventure by itself 🙃

Schwere Überflutungen und Vermurungen heute im Osten Friauls, u.a. ist der Fluss Judrio über die Ufer getreten (Bild: F. Montanari). Mancherorts sind in den vergangenen 24 Stunden mehr als 250 mm Regen gefallen.

The non-scientist’s guide to reporting on climate repair Journalist Rebekah White from New Zealand unpacks the challenges for a better climate repair reporting.

Journalists face challenges in reporting on climate interventions because the science is complex and the issues are often multifaceted. But the reporting should avoid sensationalism and try to present risks proportionately, help the public understand uncertainty, and avoid oversimplification.

This is wild! Here is a mosaic image combining satellite passes from NOAA 21, Suomi NPP, and NOAA 20 showing the auroral oval very extended during the geomagnetic storm earlier this week. I have annotated where the typical auroral oval rests over the north geomagnetic pole.

The two brightest comets currently visible in the sky, C/2025 R2 (SWAN) and C/2025 A6 (Lemmon), captured last weekend with an ASI294mc Pro on my C8. #Comet Lemmon is already bidding farewell to the northern hemisphere, so I had to catch it in the near-horizon haze. #astrophotography 🔭

Super stoked our Matterhorn-Tower-Collapse paper is finally out @egu-esurf.bsky.social. Read all about what it takes to be able to now compute in simulation how thawing and fluid water availability influences real rock slope instabilities at high altitude:

It’s happening!! And it’s glorious!

A reminder: energy isn't just electricity.

Many countries have done well to decarbonise the tip of the energy iceberg - electricity.

The hard bit is what's below the tip of the iceberg - heat, cooling and transport.

At the moment Dst is -176 nT, so a major geomagnetic storm is still ongoing. With no more major solar eruptions incoming we expect that this storm will decline now over the coming days.

Zumindest schwache fotografische Polarlichter sind sich in der zweiten Nachthälfte ausgegangen.

A fisheye lens photo showing a circular view of a clear night sky filled with stars, with the faint band of the Milky Way visible in the center. The rounded horizon includes silhouettes of trees and a parked vehicle with an open hatch at the top right edge, where a person and some gear are dimly illuminated. There are distant town lights at the left and bottom edges, giving a sense of tranquility and stargazing.

Lighthunting was a bit disappointing last night in Austria. Anyway, I took an all-sky picture yesterday evening shortly after dusk, on which at least a faintly visible SAR arc can be seen.

Location once again Koralpe, Austria.

While I was playing around videoing airplanes flying under the aurora last night, I had my other camera taking stills. Here's 1661 stills connected covering 55 actual minutes. The bright, fast moving streaks are the airplanes. I sped this up faster than normal because we all have swiping to do.

I might have taken a few aurora photos.

Ich war dabei! 😎💪

Wow 🤩

Heute gab es die nächste starke Sonneneruption. Auf den aktuellen LASCO-C3-Bildern ist ein kleiner "Blizzard" zu sehen. Diese Bildstörungen entstehen, wenn der Sensor kurz nach einer starken Sonneneruption von hochenergetischen Teilchen getroffen wird. Im Hintergrund ist der Full-Halo-CME sichtbar.💥

Here are the effects of the X5.1 flare on our ionosphere. This plot shows which areas may have radio signal disruptions. The sunlit side of Earth saw a radio blackout during the flare, and the polar regions are now experiencing some disruptions due to the radiation storm.

What‘s the point of having healthy options on the Menu with such poor Ventilation.

A #solarstorm with an initial speed of ~730 km/s is on its way toward Earth! It’s associated with an X1.7-class flare that peaked today around 07:35 UTC.
The CME is expected to arrive Tuesday, 11 November, around 20:00 UTC (21:00 CET).
Let’s hope for a better aurora show than on Friday🤞🌌

#Eisterreich heute.

Drinnen ist Luft selten so frisch wie draußen mit ~ 422 ppm CO₂

Über 800 ppm = mangelnde Belüftung = viel ausgeatmete/geteilte Luft

Gesetze für Innenraumluftqualität in öffentl Räumen fehlen

Werte werden oft überschritten. Nachvollziehbar in der indoorco2map.com
