#AR4048
Multi-spotted group AR4048 (left) is growing and it'll be interesting to see what happens with it in a few days when it's directly facing Earth.

I thought this was an interesting active region, so I went in a little closer with a bigger scope. AR4048 is that line of tiny sunspots. #Astronomy #Astrophotography

Today's Solar observation shows large sunspot group AR4048 (lower) is growing and is forecast to be 'threatening' X class flares with Earth soon to be in the firing line! #astronomy #astrophotography #solar #flares #aurora @stormhour.bsky.social @photohour.bsky.social

AR4048 and upper right 4046. Difficult seeing today. H-Alpha with Daystar Quark and Zenithstar 61. #sun #solarflare #space #astrophotography #astronomy #sunhour #daystar

Zoom in on AR4048 with its 'beta-gamma-delta' magnetic field. Ripe for an X-class. 02042024 #X-class #sun #ar4048 #sun #solar #space #sunspots #sunhour

March living up to the saying by going out like a lamb! It's glorious weather in most of the UK. Here's the 'currant bun' with two large currants! These groups look like they're ready to fire flares at us this week. #astronomy #astrophotography @stormhour.bsky.social @photohour.bsky.social

My first try with an eye roasting 3.8ND solar filter. Terrible seeing but this is AR4048 in white light on the Photosphere. The rising part of each granule "block" is located in the centre, where the plasma is hotter. #sun #solar #sunspots #space #astrophotography #astronomy

Had enough Sun this weekend? There's now a new big sunspot group so it looks like solar activity is building again. AR4048 (lower) is an active & growing region and is reported to be a greater threat for X-flares than AR4046 (upper) which delivered an X1.1-flare earlier #astronomy #astrophotography

El Sol hoy, 5 de abril de 2025 desde Gran Canaria, España. La región activa AR4048, en el centro del disco solar, ocupa más de 1500 millones de km2 y está formada por 32 manchas solares. Le sigue la AR4046, con casi 500 millones de km2.
¡Feliz sábado! 😁

Deux vues rapprochées du Soleil, en ce 7 avril 2025.

Pour une raison inconnue, impossible de ressortir la vidéo du disque complet, faite avec la Zenithstar 61. Reste donc une vue sur #AR4048, réalisée au Herschel Baader, derrière la Skywatcher 100ED

The large sunspot group AR4048. This is probably one of the last big sunspots of this solar cycle, whose maximum we just passed. From now on, and up to 5 or 6 years, the Sun will become quieter, with progressively less sunspot count. 🧪 🔭 #astrophotography

☀️ Activité solaire : on souligne une activité géomagnétique notable ce vendredi, une nouvelle fois sous l’influence d’un trou coronal. Le seuil de tempête géomagnétique G1 a été franchi. On regrette que les fameuses régions AR4046 et AR4048 aient décidé de rester silencieuses…

☀️ Activité solaire : la région AR4048 dispose désormais d’une classe magnétique Delta, propice aux fortes éruptions. L’agence NOAA estime à 25% la probabilité d’une éruption de magnitude X dans les prochaines 48h. La région fera face à la Terre d’ici quelques jours...

The Earthward face of Sol went from near spotless for last weekend’s eclipse to very active, with two massive sunspot groups visible, AR4046 and AR4048. Storms have already buffeted our local space weather environment with a Kp index topping 5 overnight, with more on the way. Aurora inbound?

What did the Sun do today? A C8+ flare from AR4048 in the SE quadrant of the Sun. The particle storm at Earth has dropped below S1 levels. #science #thesun #sciart #astronomy

Uma poderosa explosão solar de classe X1.1 foi liberada pelo sol em 28 de março, resultando em apagões de rádio na América do Norte e do Sul
Além disso, uma nova mancha solar chamada AR4048 também está se voltando para a Terra e espera-se que produza algumas explosões poderosas nos próximos dias.

🔹 AR4048 : plus intéressante et prometteuse. Grande par sa taille, elle s’est déjà illustrée par plusieurs éruptions de magnitude M ces derniers jours. Il lui manque une complexité plus marquée dans sa configuration mais qui pourrait bien se developper dans les jours à venir.
