Last night into this morning, we had the strongest aurora I've seen since 2015. We're entering the solar maximum cycle again, and I hope we see lots more of these before the cycle ends.

Hi,
I'm Pierre, F4JWJ, new ham from France.
Received my official licence just 7 days ago...
Used to live in Paris, Lyon, Bruxelles and the Corsica Island.
Now in the French Alps.

New to Mastodon, still have to figure out what hashtags to use...

The German #hamradio club #DARC has for some time now operated its own Matrix chat server https://chat.darc.de .

And that's really great!

- DARC groups can now officially and legally use chat. (If you don't appreciate that, read Art 28 GDPR.)
- All members have access, through DARC credentials. Matrix becomes an obvious choice for new activities. It sees heavy use for that.
- Outside DARC, federation means open invitation: Anyone with an account on any Matrix server world-wide can join.

#COVID am Mittag. Beginnen wir mit Intensiv.

Auf der Kinder-ITS (ohne Neo) liegen mit 28 Kindern so viele wie seit Ostern letztes Jahr nicht mehr.

Die Steigung ist beeindruckend.

Do you need the precise time?

Point your browser at https://uhr.ptb.de/ for the time from the horse's mouth, in this case, the official German time-keeping service "Physikalisch-Technische Bundesanstalt".

The Δt activates an estimate how precise your local computer clock presently runs. This can be convenient for some #hamradio endeavors needing to control clock deviation tightly.

Incredibly rare photo of Schrödinger's cat.

I always follow back, and really appreciate and follow boosters
