Six images of the Sun in H-Alpha.
During that session, the solar limb didn’t show any relevant prominences, so all the data was focused on the active regions.

#Sunspot groups AR4055 (bottom) and AR4058 (top) yesterday as they rotate out of view and approach the West solar limb. #Solar cycle 25 is just past its activity maximum. #science #Astronomy #astrophotography

Took the trusty old telescope out to capture some pics of the partial eclipse. Nice big chunky sunspot too.

Cette matinée dans la brume c'est aussi l'occasion de regarder le soleil avec un filtre naturel....

Fou de voir qu'on observe bien les taches.

The #Sun's surface. The #sunspot here is Active Region 4018 as seen yesterday through my #telescope. The granular texture is from the strong convective motion of the #solar #plasma, very much like the convective patterns we see in a pot of boiling water. #astrophotography

Two more images from the recording session on 30 august.
Each image is a mosaic composed by two panels.
The Ha filter was set up to be off-band around the 656.28 nm wavelength, on the +5 and -5 Å wings allowed by the Combo Quark. In addition, the gain was modified to according to the wavelength shift.

The #sun has 11 numbered #sunspot regions on its Earth-facing side.
Next 24 hours: The chance for C flares is 99%, the chance for M flares is 75%, and the chance for X flares is 25% today.
Next expected #CME: A coronal mass ejection from January 4 is expected to glance Earth today. https://earthsky.org/sun/sun-news-activity-solar-flare-cme-aurora-updates
