Sunspot group AR3030 imaged in white light (L) and hydrogen alpha (R). Although a M-class solar flare erupted from AR3030 on June 11, its magnetic field is now stable so there is little chance of another solar flare today (June 12). The white light image shows the umbra and penumbra of sunspots as well as an extensive area of faculae. Seeing was only fair so I was not able to resolve convection cells. The hydrogen alpha image (inverted to increase surface contrast) shows sunspot group AR3030 and several filaments.
