July 10 Solar images in H-alpha and Doppler

Imaging the Sun in Halpha and Doppler was created.

Setting: TLAPO80/480 with Solex Pro 2nd Gen slit and ASI678MM
Herschel Wedge
Tilt: 0,7 and Sx/SY 1,03
Software: SharpCap, Inti, JSolex and CS4

Filaments in different wavelenghts

 

Filaments in different wavelenghts. In CaII ion lines the filament is one big "snake" while in H-alpha and H-beta they are apart. Of course we are looking at different heights in the sun's atmosphere. 

Setting: TLAPO80/480 with Sol'Ex pro 2nd Gen slit and ASI678MM camera

Sun in Barium II D2 and H-Beta (June 20)

 

Again, I was able to make a solar image in Barium II D2 (4554A). The image of the Sun in H-Beta was very sharp as seeing conditions were good. This is probably my best H-beta so far.

Setting: Solex Pro 2nd Gen Slit with ASI678MM and Herschel Wedge.

Tilt : 0,017 and Sx/Sy 1,04

Huge Prominence June 20, 2025

 

So far, my biggest prominence ever. Captured this on June 20, 2025 very early in the morning. When I started to scan, I kept seeing a white glance after the sundisk was away. I made sure the scans were wide enough to capture the phenomen. Unfortunately I could not compile the file using Inti as a part of the scanfield was cropped. With the help of Valerie Desnoux, I could change the settings of Inti resulting in a wider field.

The prominence is about 200.000km above the sun's "surface" and about 300.000km in length; remember this is the distance Earth-Moon.

Kerrville(Texas) Louise Hays Park Flooding

 

Louise Hays Park in Kerrville - July 4th 2025

Currently due to heavy rain (>250l/m2), Kerr county in central Texas is hit by severe floods. The Guadalupe river passes through the center of Kerrville and Louise Hays Park. We visited this Park last year in April to see the total solar eclipse. According the news a lot of areas are flooding including Louise Hays Park in central Kerrville. 

Wishing a lot of strength to the residents of Kerrville and, by extension, all of Texas.
