Fast detaching prominence from March 16 2022

[Astro-BHO]

Refractor TMB LZOS 6" F8
ASI183MM
SharpCap 4.0 sequence
SolarSpectrum 32mm 0.3Å bandwidth
AstroPhysics E6oo GTO mount


The whole process only took about 26 minutes (14:15 to 14:41) and I had trouble exchanging the binocular for the ASI183MM.

Impressive!

Astonishing! It is rare that you get to see anything move in this hobby except when comparing images taken 50 year apart.

Very cool capture!!
And this is only 20 minutes? Imagine the speeds when you think the Earth globe with it!? In this FOV there can be 4 or 5 Earths in a row?

Hi
ok... I can't upload all the images of the sequence now.
But I can show the 1st picture and the last picture with the recording time

Start of sequence 14:15 UTC, file 2022-03-16-1415_2-sun


End of sequence 14:35 UTC, file 2022-03-16-14:35_9-sun

Hi
Today I edited the picture again. For reference, I measured the diameters of the Earth and the Sun and calculated the speed
of the prominence: 203445km/h
For comparison, the blast speed of TNT is 7000m/s. corresponding to 25200km/h. That's 9 times slower
At the blast speed of TNT, the prominence would have traveled less than the distance of the Earth's diameter in 26 minutes

Very cool edit Bernd!
Great show on size and speed.

Calculations like that bring things to life
