This impressive flame-like prominence was visible March 9, 2026, projecting from the southwest quadrant of Earth's Sun. The image has been reoriented for a more pleasing composition, imaged in monochrome via hydrogen-alpha light, false color applied. #solarastronomy

On Saturday, I organized a Solar Astronomy event at the local Christmas Fair. Everyone, from children to adults, marveled at the up-close views of sunspots and solar flares. Even Santa and a few elves joined in! #SolarAstronomy #ChristmasFun 🔭

Researchers use NVST high-resolution data to study chromospheric fibrils around quiescent filament Using high-resolution data from the one-meter New Vacuum Solar Telescope (NVST), a research team led by Prof. Yan Xiaoli from the Yunnan Observatories of the Chinese Academy of Sciences (CAS) has conducted an in-depth study on the physical properties and oscillations of chromospheric fibrils surrounding a quiescent filament.

The view of Sun today in hydrogen-alpha light revealed the solar limb sizzling with prominences! Here are a few views recorded late this afternoon. By the time we were able to get to this, Earth's atmosphere was riled up and cost us some sharpness.

Image of the Sun with sunspots taken by me at 1:20 PM EDT Saturday, August 2, 2025

The Sun. I imaged this at 1:20 PM EDT on Saturday, August 2, 2025, with my SeeStar S50. #SeeStar #SeeStarS50 #SolarAstronomy #Astronomy #Astrophotography #HoosierSky

Yikes! #astronomy #solarastronomy #space #solarobserving

Our sun's appearing pretty active with coronal loops coming off the limbs at the moment 👀

Hydrogen alpha scan from June 27, 2025. I was able to acquire 1 scan before a spec of dust worked its way onto the SHG slit. Still the scan is good enough to show the prominences on the western limb. #solorphotography #astrophotography #spectrohelioscope #astronomy #solex #MLAstro #solarastronomy

Hydrogen alpha solar scans from June 26, 2025. Taken in Champaign, Il. Doppler scan also included. See comments below for info about the solar structures visible in the photos.

This morning we braved the building heat and humidity and set up the hydrogen-alpha telescope for our Sun shot. Much sweat was shed. While we got a few very good images, post-processing was difficult as the #SolarToolbox script for #PixInsight ceased functioning!

We've been keeping an eye on our sun last week and over 3 days it's incredible to see the changes.

Region 4079 with 34 spots

Zoomed in and image stacked region 4079. The “tiny” spots are visible here.

Beautiful spots today at regions 4079 (34 spots) on the left and 4076 (1 spot) on the right.
