Het Belgische STCE @ksb_rob heeft een waarschuwing uitgestuurd t.g.v. #zonnestorm. Ze volgen daarmee andere instituten als NOAA (USA) en Met Office (UK). #ruimteweer Hoe komt dit? Wat betekent dit (voor jou)? Een draadje.👇 TLDR; Kans op #poollicht vannacht, als't weer meezit.

🥳A successful workshop with lots of discussions on various subjects concerning #SpaceWeather, development & future service improvements, and more.... 😍The onsite participants at @esa SWE Service Network Workshop group photo! ❤️A big thank you to all the participants and the organisers!

NOAA’s SWFO-L1 observatory executed its final engine burn, successfully entering its final orbital position at Lagrange point 1 and is now renamed SOLAR-1. Full story at nesdis.noaa.gov/news/swfo-l1…

I just have to share pictures of my backyard in Zemst, Belgium! #noorderlicht @vrtnws @NoodweerBenelux

Ik krijg van uit verschillende hoeken van Vlaanderen foto’s en meldingen dat het #noorderlicht fotografisch én met blote oog te zien is! ☀️☀️☀️

For those wondering, ACE is NOT reading solar wind speed correctly. Time of flight measurements indicate the solar storm speed average is 1660 km/s, which means the shock speed was likely well over 2000 km/s. This is not Carrington-class, but it is noteworthy. With the sustained southward field, we could very well reach G5-levels with this storm! Aurora watchers get to clear skies wherever you are. Radio communicators, expect propagation issues, especially on the nightside. Starlink users, expect internet degradation over the next 12 hours. Grid watchers and GPS users, stay vigilant. This is a big one.

Here is another video update from us here at SWPC as the final CME has arrived. Hopefully these help, please let us know if you find them useful and we'll see what we can do for future events. Stay space weather aware at spaceweather.gov

Our first experiment with a video explanation of the activity was well received, so here is an update as we continue into the overnight to morning hours. We will attempt another update later on Wednesday if warranted. Stay informed at spaceweather.gov

De #maan brengt de komende dagen een bezoek aan alle heldere planeten die nu zichtbaar zijn. Dat levert mooie samenstanden op! Vanavond (za 1 feb) is als eerste #Venus aan de beurt. Op 7 feb passeert de maan #Jupiter, en in de nacht van 9 op 10 feb staat de maan dicht bij #Mars.

(NL) #Proba3 lancering update: Als onderdeel van standaard operaties in de voorbereiding van de lancering, is er een technisch probleem ontdekt in het Proba-3 ruimtevaartuig. Lancering is nu niet eerder gepland dan 5 december 10:42 GMT/11:42 CET. Volg ons live op tomorrow➡️ esawebtv.esa.int (FR) Lancement de #Proba3 : un problème technique a été détecté sur le véhicule spatial Proba-3 lors des opérations standards liées à la préparation du lancement. Le décollage est désormais prévu au plus tôt le 5 décembre à 11h42 CET. Rejoignez-nous en direct demain

#MediaInvitation: journalists are invited to an event at the Royal Observatory of Belgium @ORB_KSB on 4 December to follow the launch of #Proba3, the world’s first precision formation-flying mission. Details and registration 👇 🔗esa.int/Newsroom/Press_Relea…

Met een voorlopig neerslagtotaal van 1089,7 mm in Ukkel is het nu (27 november) al het natste jaar sinds de waarnemingen begonnen in 1833. Vooral het aantal dagen met veel neerslag (>20 mm) valt op. Meer info op meteo.be/nl/info/nieuwsoverz… en frankdeboosere.be/klimaatukk…

ESA's Proba-3 double satellites, lifting off next Wednesday, will offer a novel view on the Sun's surrounding atmosphere, or 'corona'. A million times fainter - but larger in expanse than the Sun itself - the enigmatic corona is the source of space weather and the solar wind

🧱Fancy building your own space-inspired LEGO? Now you can fulfil your dreams with two sets that feature us! You can build your own: 🚀 NASA Artemis Space Launch System, which includes a model of the Orion spacecraft featuring the European Service Module we developed. 🌌The Milky Way Galaxy set, an artistic picture of our home galaxy made from 3,091 LEGO bricks and also features our Gaia space telescope.

The best solar event on 2024/10/29 was the big prominence eruption from the southwest limb. This became an extended CME based on the LASCO C3 image at 19:30 UT. At this time no coronagraph data are available between 12:53 (STEREO-A COR2) and 19:30 (C3).

Attention: The coming #solarstorm is going to be much stronger than predicted! It has hit Solar Orbiter, which is currently serving as a long-range upstream monitor ahead of Earth. From the magnetic field observations (see red boxed area in the magnetic field plot), the magnetic structure of the storm has either rotated slightly or SolO is hitting the "bent" part of the structure that has the solar slinky tilted on its side. We now know the structure will likely have a "SWN" flux rope configuration once it hits Earth. If conditions hold, this means #aurora will build fast when the storm hits and stay strong for about the first 6 hours or so (throughout the magnetosheath and the early part of the solar storm core). Then the field will likely flip north and the storm will no longer be a strong aurora producer at mid-latitudes. In a nutshell, what all this means is that NOAA and NASA have underpredicted the impact of this coming storm. It could easily be a G3-level or higher, *IF* the observations from Solar Orbiter are any indication. Also, this storm will arrive between early to midday October 28 UTC time!

Vanavond weer lezing over #ruimteweer! 🌞🌍 Je kan me om 20u vinden bij @VSWMira in Grimbergen. mira.be/activiteiten/2024/20…

2¹³⁶²⁷⁹⁸⁴¹−1, discovered today, is the largest known prime. It's a Mersenne prime (2ᵖ-1), which are easier to find. It took nearly 6 years for the GIMPS software to find it after the previous largest known prime. It was also the first Mersenne prime found using GPUs.

Exiting time ahead of us! #spaceweather
