"Topographic #prominence of three peaks located in Maine, US, all near the higher Great Pond Mountain. Red triangles mark the four peaks, the lowest contour line encircling each of the three lower peaks are shown in black and the green dots mark the key cols that mark the starting point of prominence. The prominences are Atkins Hill: 430 − 310 = 120 ft, Cave Hill: 570 − 530 = 40 ft, Mead Mountain: 671 − 530 = 141 ft. The parent peak of each peak is Great Pond Mountain."

I am looking to fill a 🚨 #PhD #position 🚨 (4 years, 65% E13) within the CRC #Prominence in #Language at University of Cologne. We will investigate how #LLMs can be used to simulate linguistic experiments. Deadline is January 17, details here uni.koeln/Z5MXY (and on the entire CRC: uni.koeln/66YRZ).

The Sun in H-Alpha light (656.23 nm), 22 august 2024. Prominences.

A couple of images I did manage to save from a session during a quite bad morning for imaging the Sun, due the poor seeing and the sky transparency. I did like the results, though.

The Sun in H-Alpha light, 14 august 2024. Prominences and coronal loop: a timelapse

astrobin.com/f0wxi5

Another attempt of timelapse. The road is still long.

Some nice dynamics on the limb and a faint (for my camera) coronal loop can be appreciated, though.

227 frames taken every 15 seconds

First frame: 08:99 UT

Last frame: 09:08 UT

It's time for 400! Day 1 begins with 's Chris Brookes, Masa Takanashi, and Antonio Honda vs Minoru Fujita and 's Mochi Natsumi and Kurumi Hiragi. Then ahead of their title match Mei Suruga and Hiyori Yawata takes on Sayaka and Kaho Hiromi. Then Emi Sakura does battle with Miya Yostuba. And in the main event for the Asia Dream Tag Championships PopCorn Carnival defends their titles against ShinDragon youtube.com/watch?v=7zeIim2Xhr

A quotation from Barzun, Jacques:

«
Everybody keeps calling for Excellence — excellence not just in schooling, throughout society. But as soon as somebody or something stands out as Excellent, the other shout goes up: “Elitism!” And whatever produced that thing, whoever praises that result, is promptly put down. “Standing out” is undemocratic.

In the build-up to her titleshot, Mei Suruga took on and lost to a lot of big names. One of them was Miyuki Takase. But now that Mei has climbed that mountain and conquered Emi Sakura, Miyuki is back. Can Mei avenge her earlier loss or will Miyuki be the next Super Asia Champion? youtu.be/M6G3bmXuNL4?si=TiCv9V
