☀️ The Sun today — not as quiet as it looks. What you see here are sunspot groups AR4444, AR4447, AR4455 and AR4464. Dark patches on a star 1.4 million km across. Each one a region of intense, twisted magnetic fields suppressing the surface plasma from below — that's why they appear darker: they're "only" around 3,500 K, while the surrounding photosphere burns at ~5,778 K. AR4447 has been the quite active of the bunch lately, leading flare production with several C-class events. And AR4455 — just rotating into view from the far left side — has already been firing prominences and jets, with astronomers watching closely to see what it brings. Solar Cycle 25 peaked around October 2024 and activity has been gradually declining 📉 since early 2026 — so catching a disk this busy, YEAH, is still worth documenting. 🔭😉 Shot in white light through my Takahashi TOA-130NFB telescope Sony A7RV Sony FE 2× teleconverter. The granulation texture across the photosphere — that subtle "orange peel" surface — is convection cells, each roughly the size of Greece 🇬🇷, churning beneath you. #SolarObserving

Solar Image of the Month: This exquisitely detailed image from August 6, 2024, features many dark filaments and bright patches of plage. Mark Johnston captured it using double-stacked Lunt Solar etalons on a TEC APO160FL refractor. #SolarObserving #HAlpha #LuntSolar #SolarMaximum

A closer look at the Sun’s surface. ☀️⁠ ⁠ In this image, several sunspot groups are visible across the solar disk—regions where strong magnetic fields temporarily cool the surface, making them appear darker than the surrounding photosphere.⁠ ⁠ Swipe to the second image to see the labeled active regions and get a better sense of how many sunspot groups were present during this observation.⁠ ⁠ 📸 Captured by Jason (@supe_rn_ova) using a NexStar Evolution 8" SCT and an EclipSmart Solar Filter.⁠ ⁠ #SolarObserving #Sunspots #SolarAstronomy #Celestron #Astronomy

New observatories in space and on the ground are providing us with our best views yet of the Sun — providing insight into puzzles that have remained unsolved for decades. buff.ly/S5DNO96 . . #astronomy #sun #solarobserving #solarobservatory #solarorbiter

New adaptive optics technology has resulted in the sharpest views yet of the solar corona. buff.ly/2NkQn1f . . #astronomy #adaptiveoptics #telescopes #solarcorona #solarmission #solarobserving

🌟 Team Celestron's Stephen Ramsden is known for his incredible #publicoutreach in #solarobserving. But when he decided to dive into #dso imaging, he turned to the #CelestronOrigin. After a quick setup and test run, he was capturing images like a pro! 🚀✨

The current #solarcycle is approaching its maximum: buff.ly/409X4Xf #sun #solarobserving

Join the Wabash Valley Astronomical Society for an open meeting on June 1, 2-3 p.m., followed by solar observing from 3-5 p.m. Free and open to all! 🌞🔭 #Astronomy #SolarObserving #WabashValley starcitytv.com/homepage/waba…

I took a quick phone and telescope (with filter) photo of the sun today. Sunspot group AR3664 is massive. 08.05.24 Bedford UK #ThePhotoHour #StormHour #AR3664 #solarobserving

Sunday morning solar #solarobserving

Observe responsibly kiddies. @daystar_filters #solarobserving

#OnThisDay in 2002, @NASA launched the solar flare observatory RHESSI, which become the first instrument to image gamma rays from a solar flare. Image: NASA #astronomy #solarobserving #solarflare

First clear day in some time, solar disk through the 90mm ETX is impressive! full of active regions and large spots and nice faculae on eastern limb. #sunspots #solarobserving

I took solar images today, by holding my phone to the eyepiece of a telescope, set up especially for safe solar observing. The main telescope I used is at the back of the third photo. People loved the towel I brought along, lol. 11.06.23 Bedford UK #solarobserving.

As we approach @TheNextEclipse next week in Europe, Asia and Africa here's me on @SPACEdotcom on how to observe the #Sun safely (and what to look for whether there's an #eclipse or not) #solareclipse #solarobserving space.com/sun-observing-safe…

Nice sunspot group yesterday. The Wilson effect was very clear through the eyepiece. #sun #sunspots #astronomy #solarObserving

Welcome to the AstroFest everyone! If you couldn’t make it to the Observatory tonight, join us on YouTube - we are now live! youtu.be/TD2NBNR2ocI#astrofe… #astronomy #nightskyobserving #solarobserving #koperniklivestreams

Join us this weekend, Friday, 9/30-Sat, 10/1) for the 40th Anniversary of the AstroFest. It is an onsite event, but all presentations will be streamed live on YouTube youtube.com/user/KopernikObs… #astrofest #astronomy #nightskyobserving #solarobserving #koperniklivestreams
