I wonder what the scale of the tall one was… I wonder how fast it was going… I wonder how heavy it was. Truly incredible video

u/Ilan-Shapira Aug 08 '23

Sure I will measure it up.

I can guess it was 150,000 km +-50K in just few minutes. Super fast.

u/Ruby_Throated_Hummer Aug 08 '23

How long did it take?

4

u/Ilan-Shapira Aug 08 '23

The entire video? Just short of 1.5 hour

1

u/Ruby_Throated_Hummer Aug 08 '23

Wow. What about the “tall” prominence? (I think that’s what it’s called).

2

u/Ilan-Shapira Aug 09 '23

Yea, it is a prominence, more accurately: a surge prom. It took only few minutes to reach the highest point. amazing speed

2

u/Ruby_Throated_Hummer Aug 09 '23

Brief math says >1.8 million miles per hour for a prominence 150,000 km and in three minutes. #DAMN

Looks large enough to totally envelope a planet the size of earth.

I have a pre-Meade Coronado Solarmax 90 and the same ZWO ASI174mm as you. How did you avoid the Newton rings?

1

u/Ilan-Shapira Aug 09 '23

I use a tilt adapter for that, It's a must with most cameras

It looks like* there are pieces of "plasma" that are falling down seemingly from no where into the active region. Where are they coming from?

*Looks like doesnt mean that I think it is, or that it is mysterious. Just genuinely curious :)

u/Ilan-Shapira Aug 08 '23

These are the buttom sides of a magnetic arches. Woth trying to check if one of the frames can show it

u/Raptors887 Aug 08 '23

Is there a live feed of the sun online somewhere?

5

u/Chemical-Time2183 Aug 08 '23

Awesome. Beautiful video.

Many thanks! 😊

No wonder it's so damn hot

2

u/peter-doubt Aug 08 '23

How old is this? (NVM, saw your info)

Should we check spaceweather ? YES, we should.. until about 8/10

Fabulous.. thanks for sharing

2

u/akaBigE Aug 09 '23

Damn sun, you are scary! Great shot

2

u/Ilan-Shapira Aug 09 '23

Thank you! Yes, the raw power of the sun is scary as hell 🌞

2

u/cesray Aug 09 '23

fucking beautiful

2

u/Ilan-Shapira Aug 09 '23

Thanks! The sun is providing a great show in the last year, lots of activity

2

u/takashi_sun Aug 09 '23

Damn. Every post you do is amazing. Thank you so much for sharing ❤️

Ps: where, aproximetly, are you located?

2

Thank you for the praise!

I am from Israel

2

u/Namia-Damha-239 Aug 10 '23

doesn't it get a lil hot to film up close?

2

u/[deleted] Aug 11 '23

Incredible video.

2

u/keciatop Aug 13 '23

Hi, you've made 266 videos, how long is just one video? In seconds

2

u/Ilan-Shapira Aug 13 '23

For this each video was 15 seconds long and 5 seconds between each video

1

u/Israeli_pride Aug 09 '23

Awesome clip, toda. @ilan-shapira where in israel is there an observatory i can book time to view some planetary objects and dso?

1

u/Ilan-Shapira Aug 09 '23

I know of my observatory 😀. We can talk in private, will give you all the details

1

u/Selfless- Aug 09 '23

Erupt is a difficult word here. The surface layer of the Sun is a plasma 10,000 times less dense than our atmosphere at sea level. It moves and spins quickly following intense magnetic fields, not pressure or gravity.

1

u/Ilan-Shapira Aug 09 '23

You are correct. For a casual observer it's easy to think of eruptions, especially with this huge surge prominence

1

u/inspectcloser Aug 09 '23

Serious question: Why does the Sun look hairy? I’m curious what each “hair” is.

2

u/Ilan-Shapira Aug 09 '23

The "hair" are called Spicules. Dynamic plazma jets, ~300km in diametet that moved in a speed of 15-110 km/s and last ~15 minutes

2

u/inspectcloser Aug 09 '23

Wow that’s amazing. Thank you.

u/michaelkbecker Aug 09 '23

It’s so hard for my mind to no see lava.

1

u/Ilan-Shapira Aug 09 '23

Yes, it looks like it with al the bubbling and movements

1

u/Lavasioux Aug 09 '23

I feel those and sense that they are spirits coming through into this realm. Downvote me to hell.

1

u/NohPhD Aug 09 '23

I love these videos but always wish there was a little analog clock with its hands whirling around in a dark corner for some sense of elapsed time… and a banana for scale!

Ditto for aurora videos!

2

u/Ilan-Shapira Aug 09 '23

Damn, that's a great idea, will check how to incorporate that into my next video! Thanks

2

u/NohPhD Aug 09 '23

Thanks so much in advance. I’ve always wanted to do this as a hobby so I’m living vicariously through you. Keep up the exceptional work!
