Dans un monde chaque jour plus austère, l’émerveillement est une qualité essentielle. S’il y a la moindre chance que l’on puisse tous sortir de notre paralysie face à l’apocalypse qui s’en vient, l’émerveillement aura un grand rôle à jouer. #naturephotography #nature #BlackAndWhite #picoftheday

Perfect day for DXing on 144MHz band ! #hamradio

Petit moment détente avec le stagiaire de terminale (en remote) qui pourrait être mon petit-fils. Comparaison entre Goldorak et Albator 😂 Je suis #teamGoldorak, lui préfère Albator. Les deux sont là pour sauver notre galaxie, c'est le principal.

Following changes by @celestrak.bsky.social, it's possible some users of SatDump (I've already gotten reports, especially for anyone running more than a single SatDump instance) will experience issues updating TLEs. I have no easy way to fix this at the moment...
