Hi all,

 

I woke up to just overcast skies and had no ability to see this and was worried since it's my only day off to miss this big filaprom on the limb that I've been waiting on since much earlier in the month when it developed in the grouping with AR3032 and friends. It looks like parts of it are finally lifting off (captured a bit of it floating away) but it has kept a good anchor to the surface despite all the recent blasts. It's not a particularly tall and action packed prominence/filament (filaprom!) but it seems to be rich with material and thick. Quite the plasma wall, like mighty serpents on the surface. I didn't get a chance to see it today until around 7pm eastern time, it was quite late for my obs usually and seeing wasn't great, but managed some moderate resolution captures to be able to make a fairly large mosaic here of the entire region and included some other notable features near by for interest along with an Earth Scale.

Awesome Marty!  It was barely rising above the limb when I got my shots this morning.

Very beautiful work.

I was following it around 7pm and my scope had a wall shadow on approaching the aperture it was so low on the horizon relative to my obs walls. I was hoping it would lift off a bit more today, but only a few chunks seem to have risen from that one side in the AR grouping. The rest has steadily held fast to the surface for so many days without any major changes. Great plasma wall or solar serpent! If it lifts off in the next day or so, it will be spectacular for sure!

 

Very best,

Great images Marty!

I haven't seen that filament since the 16th, but may have a chance tomorrow if there's anything left to see.  Mostly been clouds/rain here, but since we're in extreme drought I'm not really complaining!

That is huge!

It will still be there, if you look at GONG/SDO archive you can get an idea of about how much is visibly noted moving in a period of time, say 12 hours, or 24 hours. You will certainly still see it on the limb tomorrow morning and into the afternoon. Two days from now it will mostly be past the limb but if it lifts off some or a lot it will still be something to see!

 

Visually it actually looks bigger to me, quite the thing to see with your eyes!

 

Very best,

Absolutely stunning Marty! Bravo.

Excellent Marty!!!

[wxcloud]

Looking amazing as usual! 

[R Botero]

That is a huge one! Great images 😎

Fantastic captures Marty.  The sheer scale of that filament is staggering!  It has been firmly attached for days now. Is it possible that it could actually transit the far side and come back again?

It's possible but unlikely. As we get closer to the maximum we may have some repeat transit AR's. Proms generally last less long, especially big fat ones like this, it's already started to lose some material that lifted off. But the AR has been fairly calm so it hasn't blasted off chunks or disrupted flow around those poles. So while it's possible, its just highly unlikely it will stick around long enough to be seen on the Eastern limb. Those AR's are likely to decay to gone by then too. But as we approach 2025~2026 we will have bigger meatier things that possibly do double transits!

 

Very best,
