About this image

It's some time since I've imaged the Sun in H alpha, and it has become a bit more active in the meantime. Shown here are AR 2859 (N) and 2860 (S). There's some filaments but little in the way of prominences. This is an image stacked from a single-exposure run. Seeing was poor, so the image is quite soft.
