About ARISS:
Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the International Space Station (ISS). In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the ISS National Lab and NASA’s Space Communications and Navigation program. The primary goal of ARISS is to promote exploration of science, technology, engineering, the arts, and mathematics topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students. Before and during these radio contacts, students, educators, parents, and communities learn about space, space technologies, and amateur radio. For more information, see www.ariss.org.

here my received files:

unfortunately the SatNOGS SSTV decoder does not work well, but there is a trick:
1) Install SOX on your Windows computer
2) Install MMSSTV
https://hamsoft.ca/pages/mmsstv.php
3) on the SatNOGS Observation go to Downloads and right-click on the Audio button to save the .OGG audio file
4) Convert .ogg to .wav for MMSSTV
in the directory (using CMD for example) you can use the following command line (or write a batch file) to convert the OGG-File to Mono and samplerate 11.025 kHz. Rename the files accordingly..
"C:\Program Files (x86)\sox-14-4-2\sox.exe" in.ogg -c 1 -r 11025 out.wav
5) Open MMSTV and load the above out.wav file in the play dialog box. You might first enter *.wav in the search box.
6) Voila !! This way you can view the SSTV transmissions from around the world...

Hallo alle zusammen,
erster Überflug von heute, bei nur einer Elev. von 21 Grad, darum nicht toll.
73 Josef
Hallo zusammen,
beim zweiten Überflug von heute habe mir mehr Erhofft, bei einer Elev. von 87 Grad.
Das erste Bild wurde wie üblich in PD120 übertragen und das zweite mit PD180.
73 Josef
Hallo zusammen,
der dritte Überflug von heute bei 45 Grad Elev. war bis jetzt das beste Ergebnis. Ich glaube bei direkt Überflüge nehme ich nicht mehr die Discone Antenne sondern die X50, mal schauen vielleicht ist es besser.

Hi all,
the time between the transmissions has been reduced..

Dear All
I received a few pics, mostly with noise. The one seen below was the best:
