The Sun: 2022 July 10
The sun imaged in hydrogen-alpha at 04:07 UT on 2022 July 10, featuring a chromospheric disk full of activity and many varied prominences around the edge. AR 3055 is lower left while AR 3053 is left of centre; north is up. Filaments up to 300,000 km in length are present in the southern hemisphere. Impressive!
Lunt 102mm solar telescope with ZWO ASI174MM video camera; frames selected and stacked in AutoStakkert, wavelet sharpened in RegiStax 6 and colour added in Photoshop CS5.
