Solar Imaging Session - October 17, 2026

The sky this afternoon is partly clear and seeing condition is very good. AR4551 Region continues to be the biggest group on the Sun's disk while AR4557 Region is starting to slowly grow in structure. In Ha wavelength, there is a small flaring activity beside AR4551 Region as well as a nice large eruptive prominence in the East limb.
