solar eruption today 23/9

[Peter Drew]

Spotted it at 2.10pm so don't know exactly when it started.  Huge, very bright eruption, the main part of it heading out into space rapidly leaving behind a long straggling trail  of material.  Followed the main component until 3pm  when a bank of cloud intervened.  The distance travelled placed it outside of the field of GONG and I've never seen such a bright surface of the plasma that far from the solar surface.  No sign of any of the associated activity by 3.30pm.  Highly detailed and fast changing in appearance, hope someone managed an image or specially an animation.    🙂

Sounds fantastic, much better than the cloud cover I had ☁️.

It's worth doing a proper study, but anecdotally I would say that large solar eruptions seem to be caused by thick cloud cover over back garden. There is certainly a causal relationship

Interesting. Looking at gong I think it's there on the SE side or 4 o'clock though it goes out the fov. Clicking on the play icon shows the animations, I regularly check back to see what a month's imaging looks like in motion.

Not only does cloud cover cause solar eruptions, it lasts precisely as long as the eruption. Fact.😂

The images and animations that I've seen so far really don't do the event justice, either too fast or too small scale.  I was using a 150mm Ha telescope at 150x and viewed the activity for an hour.  The main object was like a thermo-nuclear fireball and the elongation from the solar limb was approaching a solar radius before fading.  I was very fortunate to witness this event.     🙂

Peter, that sounds like you did indeed have a moment of good fortune in observing this.
With that 150mm it must have been quite a view.
