Captured on May 25, 2020, from my backyard near Dark Sky® Alqueva region, Portugal, with a Solar Ha telescope – at the wavelength of Hydrogen-Alpha, the high-resolution image features a gigantic solar prominence visible in great detail around the sun´s limb due to an exceptional seeing conditions (very good atmospheric stability). The sequence of close-up captures were taken between UT 13h41 and UT 16h00 (Universal Time) when the seeing was more stable to help reveal very interesting changes in shape, intensity and detail, with minor eruptive prominences appearing around the limb. The full disc image, captured around noon, also shows the large prominence visible at the right northern edge of the Sun. As in average the solar disc has a diameter of 1,391,000 km, we can determine that the large prominence could reach around 83,000 km high, which means 6,5 times larger than our planet Earth with a diameter of 12,742 km. To see a comparison with NASA images taken by SDO – Solar Dynamics Observatory, at approximately the same time and date, take a look here.
To help reveal the prominence flames in motion, I made a time lapse compiling 27 shots processed, each one as result of a stack of the best 250 frames from each raw video. The final result is a 2K high resolution time lapse movie from the images captured between UT 13h41 and UT 16h00. Due to vimeo algorithms it may shows a little compression, which is not visible in the .mov master file. Don´t forget to put to sound on.
