Auf dem Bodensee gab es heute eine Wasserhose:

Auch nicht gerade üblich im ersten Junidrittel. Ob das Wasser mit der End-Mai-Hitzewelle etwas warm wurde?

Wieder diverse Halophänomene zu sehen..






um 18 Uhr:






halt Weitwinkel zum filmen, ich wollte soviel wie möglich erwischen :

Vielleicht weiss jemand, wer eine Radiosonde im Bergell gestartet haben könnte.
Imet-4 Radiosonden werden vorwiegend von Hochschulen verwendet.

Inzwischen sind es schon 6 Radiosonden Gestern zwei, heute bisher vier.
Die wurden wohl etwas westlich von Vicosoprano gestartet.

A SPACEX ROCKET IS GOING TO HIT THE MOON: A SpaceX rocket will hit the Moon this summer, and NASA wants your help observing the impact.

On August 5th at 6:35 UTC, a Falcon 9 upper stage left over from the launch of Firefly Aerospace's Blue Ghost lunar lander will slam into the Moon near Einstein crater, according to Bill Gray of Project Pluto. The 4-ton rocket body is expected to strike at 2.43 km/s, excavating a fresh crater 10 to 20 meters wide and throwing lunar debris high above the impact site.
"Citizen scientists may be able to help us observe this event," said Brian Day of NASA Ames Research Center and SSERVI in a June 12th briefing. "Observers in the Americas will have the best view."

When the rocket hits, it will produce a flash of light, much like natural meteoroids do when they strike the Moon. However, the rocket will be crashing slowly into daylit terrain, and "the flash may be too faint to see," noted Bill Cooke of NASA's Meteoroid Environment Office at the same briefing. Indeed, he says, it could be as dim as 17th magnitude.

Of greater interest is the impact plume. Cooke estimates the collision will hurl as much as 800,000 pounds of debris above the lunar surface. If sunlight catches the expanding cloud, it could become bright enough to see above the Moon's limb.

This isn't the first time a rocket has hit the Moon. During the Apollo era, NASA routinely crashed Saturn V rocket stages into the lunar surface to generate moonquakes for seismometers left behind by astronauts. In 2009, NASA's LCROSS mission crashed a 2.3-ton Centaur rocket stage into the lunar south pole in a successful search for water ice.

None of these previous rocket impacts has been convincingly observed by amateur astronomers--so this would be a first if anyone sees it.

Want to try? We will provide updated crash-site coordinates and observing tips as August 5th approaches. Stay tuned!

Quizfrage: Von welchem Ort in Deutschland hat man einen solch schönen Blick auf die Berner Alpen?

Dryline Feeling heute Nachmittag. Wind dazu sehr böig.

Hab ich ganz vergessen..hier noch die Videos zu den fantastischen Halo's am 8.6.26 und 11.6.26:


Ich finde vor allem dieses Video sehenswert :



Beide Tage gabs wirklich seltene Halo-arten zu sehen, vorallem der Horizontalkreis war extrem ausgeprägt.
