Details:
On June 3rd, when I was looking at and imaging the Sun, I was fortunate enough to capture a nice example of Coronal Rain while taking a series of images of some nearby solar prominences.
Coronal rain forms when hotter plasma in the Sun's corona cools down and becomes denser. Like raindrops on Earth, coronal rain is pulled down to the surface by gravity. Because the plasma is electrically charged, it follows the magnetic field lines, which make huge arches/loops, instead of falling straight down.
This spectacular phenomenon is seen as cool material seemingly appears out of nowhere and appears as bright, elongated structures, often resembling glowing strands or streaks. This can be seen in the upper right-hand corner of the attached GIF.
I used a Lunt 60mm single stack solar scope, ZWO ASI174mm camera and an Explore Scientific 2x Barlow lens. The GIF, consisting of 62 individual frames, begins at 10_27AM and ends at 1_25 PM.
