It's obviously harder to commute uphill to the Paris Observatory with the snow, but the stunning view makes it worth it! 🔭 ❄️

While playing with the LIDAR images in www.geoportail.gouv.fr from @ign.com I remembered that when I was a kid I used to walk in the forest up to the ruins of what we believed to be a motte-and-bailey castle. It is clearly visible here with its circular shape surrounded by ditches.

The @vrubinobs.bsky.social has a seismometer inside the pier which is supporting the telescope. Out of curiosity I had a look at the data after the mag 8.8 earthquake that occurred in Kamchatka on July 29th and to my surprise I got the following !
