Luca, this is specatular!
Being a relative newbie to solar observing, especially H-alpha, I have a few questions regarding what I am looking at. To my untrained eye, I can see what I interpret as the leading sunspot in 11029, and its penumbra. If this is true, then I am seeing features on the photosphere, through the chromosphere....right?
The fine spicules (sp) at upper left appears to be directly over the smaller trailing spots. Can anyone explain them? Or, the bright filamentary structure between the lead spot and the smaller trailing spots?
Thanks!
