The Sun may or may not be waking up after a long slumber but one solar phenomenon which continues to impress, even through periods of low solar activity, are prominences. In order to see or image prominences you’ll need a hydrogen-alpha (h-alpha) filter designed for solar work. (Note that deep-sky h-alpha filters are unsafe for viewing the Sun.)
Viewing the Sun through a solar h-alpha filter removes all wavelengths except those centred on 656.28nm, the primary emission or absorption line of hydrogen in
