Details:
I posted some white light image of the Sun yesterday showing the new sunspot group AR2629 and also the darker sunspot AR2628 that’s now rotating toward the western limb. But when you look in a dedicated solar telescope at the Sun in the H-alpha wavelength you can sometimes see so much more incredible detail.
This is what happened yesterday when I decide to take off the white light refractor and have a look at the Sun with my solar telescope…to my surprise and delight there on the eastern limb was a large prominence firing away out into space, not that far away from the new sunspot group AR2629.
I’ve noticed that when a prominence is displayed like this on the eastern limb, that within a day or two a new sunspot group shows its presence on the surface of the Sun…I wonder if this will happen again and we’ll have another new sunspot soon…
Images were taken with a Lunt 80mm solar telescope and a Canon 700d camera with a 2x Barlow lens; this is a composite image to capture the different exposures needed for the solar disc and the faint prominences. Exposures were 1/200th second and ISO200 for the solar disc and 1/15th second and ISO 200 for the prominences.
