Today’s H-alpha image shows ongoing major prominence activity along the NE and NW solar limbs with smaller prominences along the SW limb. The NE limb shows large loops of sun stuff rising high above the chromosphere.
Today’s sunspot image shows a new active region, AR4087, emerging from the eastern solar limb. AR4084 has disappeared.
The gallery below showcases today’s larger prominences. These images are simply cropped sections of the H-alpha image at the top of this page.
Below is an image of the NE prominences that is not cropped from the H-alpha image. Instead, this rendering is a stack of images from a 180sec AVI of just the NE limb. It gives us a different level of detail while over-exposing the solar disk. This is the technique that solar imaging folks use to create time-lapse images of solar prominence activity. I have not yet attempted that, but I am working toward it.
