Our sun, winner: Active Region of the Sun’s Chromosphere by James Sinclair

This photograph from Utah in the US shows the #chromosphere, the most picturesque part of the sun. Composed of hydrogen and helium plasma, it is manipulated by the intense and tangled magnetic fields of the sun. The chromosphere does not just change day by day, it changes second by second, which is why solar astrophotographers become obsessed with it.

Recent Solar adventures

October 3, 2025 — We had been having quit a lot of trouble lately, recording data and reproducing images of Sun with prominences. There was some early success but even those images were a struggle to produce. Taking a look at suggested camera settings found in an article on solar imaging, one thing stood out — gain! We had nudged the camera’s gain setting upward and that’s not helpful and certainly not recommended; the setting should be very low or even zero! A few adjustments in data capture parameters was all it took to make a big difference in image processing and results!

We’re very pleased with Barlow-boosted views, shown here, though we’re still having some issues with achieving even lighting across whole-disk views — just can’t seem to get them tuned right with the Coronado SolarMax III. Visual observing was also very good, especially with the TeleVue 10mm eyepiece. October 3 conditions: Clear sky, temperature of 74°F, light southeast wind.

‪Here are some great shots from our #GREGORSolarTelescope observation campaign in July. Peering into the #photosphere and #chromosphere, we caught several emerging active regions – and a #flare! This will help us study the plasma dynamics in active regions and how energy builds up to create a flare.

Last year, #ISRO 's solar probe #Adiyta-L1 witnessed a X6.3 #flare and captured 1st images from the #chromosphere. Published today by scientists led by #IUCAA and including #MPSGoettingen in #TheAstrophysicalJournalLetters. More here: https://www.mps.mpg.de/8324638/news_publication_24282801_transferred?c=6775 ☀️🔭

The Sun in H-Alpha light (656.23 nm), 22 august 2024. Prominences.

A couple of images I did manage to save from a session during a quite bad morning for imaging the Sun, due the poor seeing and the sky transparency. I did like the results, though.

Fun with the #Sun papers 1/3 ... Solar mean magnetic field of the chromosphere: https://www.ias.ac.in/describe/article/joaa/044/0056 -> "the SMMF at the #chromosphere is weaker by a factor of 0.60 compared to the #SMMF at the upper-photosphere. The correlation analysis between them gives a Pearson correlation coefficient of 0.80. The similarity and reduced intensity of the chromospheric SMMF with respect to the photospheric SMMF corroborate the idea that it is the source of the Interplanetary Magnetic Field (IMF)."

Hello #Astrodon folks! I wanted to #introduce myself. This is a #SciComm account for the Solar eruptioN Integral Field Spectrograph group. We're building a new instrument to study the sun! It'll help our understanding of #SolarPhysics, #StellarPhysics, #SpaceWeather, and #AerospaceEngineering.
If you'd like to learn more about the #Sun, the #SolarCorona, or the #Chromosphere, give us a follow!

On Sunday it was 8 years to the day since I photographed the biggest solar #prominence I've ever seen. It was 100,000 km tall & that tiny dot is the approximate size of Earth to scale. Taken with a #CoronadoPST + Canon 1100D with 2x Barlow #Sun #SolarImaging #SuninHAlpha #Chromosphere #SolarFeatures

My piece of photography "Shining through the valley", highlighting that moment during an eclipse when the lunar mountains have covered up the sun's disk, the only direct sunlight left being little "beads" that effervesce before the last plunge into total darkness.

This particular example, the only one I've yet seen, comes from the August 21, 2017 total solar eclipse.

When we observe the sun under Ha filtering, we are able to see the sun's #chromosphere and its #prominences. The chromosphere is a gaseous layer, mainly hydrogen, which lays above the #photosphere. The high temperatures at that layer causes the hydrogen to glow red at that wavelength, hence the Ha name. Also, you could be able to see a #prominence, which is an eruption-like event of solar material thrown out into space!
