It is with great sadness that I wish to inform you of the sudden passing of Serge Koutchmy. He will be sorely missed as a longtime personal friend, and as a friend to many among the solar physics community. My thoughts are with his daughter Natalie and his son Valéry.

@XavierJubier @astrotibo @VigieCiel Donc par rapport à l'horizon faut que je regarde à 50° ?

I live in Fécamp (at the end of the fleche) just below the entry point (red mark), I will go to the beach to film (4:00 am). Can you tell me in which direction to look so as not to miss my video? #Sar2667

@decaurel76 @astrotibo @VigieCiel Vous l'avez vu? Très bref depuis Paris.

@XavierJubier @astrotibo @VigieCiel Ca marche, merci Xavier en espérant vous montrer un beau résultat 👍

@decaurel76 @astrotibo @VigieCiel Oui le Zénith c'est 90.

@XavierJubier @astrotibo @VigieCiel Au dessus c'est 90, non ?

@decaurel76 @astrotibo @VigieCiel Et commencez à filmer une minute avant si possible. Bonne chance!

@decaurel76 @astrotibo @VigieCiel Il arrive par l'ouest et se dirige vers l'est. Depuis votre position pointez votre caméra vers le nord-nord-ouest et choisissez si possible un objectif grand angle.

@gblasco78 Indeed😎 *shoot it down, strange typo!

@XavierJubier They are watching superbowl now, dont worry

On February 13 at around 2:59 UTC, Le Havre & Rouen, northern France, should be in for Sar2667 cneos.jpl.nasa.gov/scout/#/object… the first 2023 #ImminentImpactor . From Paris, look towards the northwest, from London to the south and from Brussels to the southwest.

@Astroguyz Then have a look at metsahovi.fi/sun/eclipse_20…

@pietrozucca @LOFAR @peijin94 @ASTRON_NL Have a look at metsahovi.fi/sun/eclipse_20…

Eclipse from @LOFAR at 50 MHz. Preview prepared by @peijin94 @ASTRON_NL First Eclipse at 50 MHz!

The 2022 October 25th partial solar #eclipse as seen from the 14-meter radio telescope at the Finnish Metsähovi Radio Observatory. metsahovi.fi/sun/eclipse_20… #SolarEclipse

A couple more images from the 2022 October 25th partial solar #eclipse taken from the southern suburbs of Paris, France. The sky wasn’t completely clear, clouds were constantly drifting in front of the Sun, the stability not too great at the beginning but improving near the end.

Maximum, 13% obscuration, of today’s partial solar #eclipse from the Paris suburbs. The sky isn’t completely clear and the stability not too great.

This "warm up" Annular Eclipse 14 Oct 2023 will start in Oregon, pass through Nevada, New Mexico, Texas & more! To see if your favorite places are in the path check out this interactive Google map: xjubier.free.fr/en/site_pages/… Thank you @XavierJubier & @GreatAmericanEclipse!

One year from today--Oct 14, 2023 Parts of the U.S. will have an Annular Eclipse (where the moon doesn't quite cover the sun). It will be a Dry Run for the TOTAL Eclipse of the Sun coming to N. America less than 6 mo later-- April 8, 2024! JOIN US! yurisnight.net/eclipse

@dermuehle @Astroguyz @_autoevolution_ There were multiple pre-production Concorde and they all achieved a top speed of Mach 2.2+ which is why I omitted the second decimal. Given what André Turcat told me and print-outs at my disposal it’s safe to assume the Mach 2.6 figure is pure fiction.

@Astroguyz @XavierJubier @_autoevolution_ found this on Key Aero: Concorde top speed key.aero/forum/commerci… - Mach 2.23 and 2.21 according to British test pilot Brian Trubshaw

@Astroguyz @_autoevolution_ Mach 2.2 is the official top speed and André Turcat, the test pilot, told me higher speeds could stall the engines and damage the airframe.

@Astroguyz @_autoevolution_ [3/3] Unfortunately test pilots André Turcat and Jean Toussaint Franchi are not with us anymore. Without the flight parameters print-out, and I’m sure they still exist in the Concorde 001 archives, we shouldn’t take this top speed seriously.
