The Sun: 2022 July 4
The sun imaged in hydrogen-alpha at 04:12 UT on 2022 July 4, featuring a chromospheric disk relatively devoid of activity, but with nice large prominences around the edge. AR3046 is the small group in the NE quadrant; south is up. The best prominence was found in the SE quadrant and shown in close-up in the inset.
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.
