Total Solar Eclipse Kerrville Texas - Report

Today, April 8, 2024 was the day we planned for... the solar eclipse. At half past four this morning we left San Antonio for Kerrville. The latest weather forecast  were no't good at all and we even had some droplets falling on the way to Kerrville.







We arrived at six o'clock and went straight to the parking lot..... and it closed. So we drove back for a couple of miles to stop at Starbucks for a coffee and muffin! At seven o'clock we drove back to the parking lot and took the shuttle bus to the recreation park "Louse Hays Park" in the middle of the city. 







Everything was ready for the Kerrville Eclipse Festival. The park was still empty when we arrived around a quarter to eight, but it was filling up by eleven o'clock up to 20.000 people. In the meantime, we had already met people from Seattle, Chile, Mexico, etc. Everyone was in a good mood and willing to have a chat. NASA was also present and provided the necessary explanation about the solar eclipse. Astronaut Reid Wiseman gave an interview. He was recently named commander of NASA's Artemis II mission to the moon. 






 Despite the cloudy sky, the sun regularly came through and we could enjoy the natural spectacle. Just as the sun completely disappeared behind the moon, the sky opened slightly, just enough to see the full solar eclipse. It remains an amazing phenomenon: it slowly gets colder and darker until it is as dark as night. As befits a festival, a group also came to sing: Judah and the lion. They played country/folk music and quite a few people stayed around to listen. Despite the clouds, it was still a successful eclipse.











After leaving the park we went back to San Antonio which took us 1 hour longer due to traffic jams.




We found out that a couple a days before the eclipcse,  Kerrville issued disaster declaration.

ATT Essen 2024

It was my 6th time I visited the ATT Essen. This time I was a little bit nervous as I went with my new EV. But at the end... no reason to be nervous as at a walking distance 8 charging stations were available. We went with 5 collegues and two cars. It was Johan R's first visit to ATT Essen and he enjoyed it greatly. As a conclusion, ATT Essen (May 4, 2024) was again a great succes with a lot people. Lot's of material, learnings, discussion and of course some good fun! Thx to Walter, Jean-Claude, Johan R and Jean-Marie

Sun Halo

 


Some halo's around the Sun this late afternoon:
- 22° halo
- Sundogs
- Upper tangent
- Circumzenithal arc
- and below the circumzenithal arc touches the supralateral arc

The supraleteral arc is not quit circular and thus I guess it's not the 46° halo.
