Today’s H-alpha solar image shows more prominence activity along the NE limb where a filament ends at the solar rim where the prominence arises – the prominence and the filament are the same phenomenon. There is additional activity along the sun’s NW and SW limbs.
The corresponding sunspot image shows only two active regions – AR4087 and AR4088.
The main prominences appear in the gallery below as cropped regions of the H-alpha image at the top of the page.
Below is a comparison of the NE limb prominence cropped from the main image vs imaged separately. The separate image on the right is sharper and seems to reveal more detail in the prominence itself. Judge for yourself.
