    A large solar prominence [OC]


    I got a nice and really large prominence on the Sun, imaged last friday 21.03.2025 at 11:31 UT

    I put the Earth in this image (to scale) for a size comparison

    Equipment:

    • Lichtenknecker 90/1350 refractor with Coronado Solarmax 90 I (Ha-filter)

    • QHY5III678M

    Image acquisition:

    • 5000 frames capured at 42.5 fps Gain 0, 5 ms exposure time

    Stacking and image processing:

    • Stacking of the best 320 images in Autostakkert3

    • Sharpening in ImPPG

    • Adding false colour in Photoshop, contrast, sharpness and brightness

      And keep in mind the sun is small in comparison to other stars out there 👀

      I’m presuming this is linked to those crazy Aurora Borealis videos posted from Alaska lately?

      Does anyone want to take a stab at describing what would happen is such a prominence were to strike the Earth? What are the densities, energies, and duration involved? Would it ‘just’ strip off the atmosphere or incinerate the planet? Mad respect for those who can apply hard science to these kind of ‘what if’ scenarios to bring science to life, like Randall Munroe and his xkcd comic
