What is this? (Strange objects in Ha wavelength)
What do you guys think? At first I laugh it off as somekind of sat/bird but then I realize the scope is capturing in Halpha and the object must be outside of the earth amosphere. The way the last object wobbles/accelerate also look weird. Could it be some kind of satelites that reflects sun light?
The video is not mine. I ran into it on FB page Solaractivity and thought it's worth considering.

Re: What is this? (Strange objects in Ha wavelength)
They are more than one and two of these move too erratically to be satellites. I absolutely have no idea what they are.

Could it be some fast moving prominences? If it is then it must be going quite fast.DeepSolar64 wrote: ↑Fri Jun 11, 2021 3:26 pm They are more than one and two of these move too erratically to be satellites. I absolutely have no idea what they are.

Re: What is this? (Strange objects in Ha wavelength)
Hi
They look like insects to me, very common when using wider band width for prom viewing.
I don't know why or how they light up like that, sometimes you can get massive showers of them in the high atmosphere.
I have seen showers of them through a coronagraph, this is where they were first documented in the early days of solar narrowband imaging.
I am surprised more people don't document them.
Cheers Rod

I believe they could also be birds

Re: What is this? (Strange objects in Ha wavelength)
As Rod has said, most likely insects, very likely a satellite too (as there are so many of them up there), space-junk and one or more balloons too.
Quite common and usually seen after image processing (unless one is glued to the pc-screen during downloads) - ones eyes I mean... !!!

I have seen insects/birds inside the atmosphere going in and out of the sundisk.
But they all leave a black silhuoette against the bright sun disk, not light up quite as bright as the promineneces. Are the bird/insects supposed to light up against the black backdrop like that? I have the impression that the object is emmiting /reflecting Ha.
https://m.facebook.com/story.php?story_ ... 1645546304
Here is how I usually see bird/insects in the frame but never seen it light up outside of the sun disk (perhasp it's because I never over expose the disk even when on the limb?)

Re: What is this? (Strange objects in Ha wavelength)
I must admit the artefact/(UFO)/whatever starting at 0.22seconds into the video does look quite interesting, as possibly seem to be disturbing the prominence (behind or in front) somewhat, but that could be a snag with imaging too.
Much depends on the actual real-time of the individual captures, versus the possibility of speeding-up or slowing-down the final video...
One way or the other, we may never know...

Re: What is this? (Strange objects in Ha wavelength)
Hi,
As others said those could be birds and they look white due to the fact that you have overexposed and as they reflect light there are seen in the images of the video too.

Thanks. Maybe I have never seen this because I have never over expose the disk even when on the limb. Always do 1 shot for both limb and disk

Re: What is this? (Strange objects in Ha wavelength)
I would say it was pollen grains as they are Halpha bright. I saw this all the time when using my Coronagraph. I have a video but the last time I shared it here no one could view it. I could view it fine on an Apple

Re: What is this? (Strange objects in Ha wavelength)
Hi Insects do light up against the black background.
Mostly seen in coronagraphs and prominence telescopes where you are using a much brighter image than we normally use with our full disk Ha telescopes.
I have seen what appear to be millions if them like rain in an older Lumicon prominence scope.
As you say birds only appear as black shadows on the disk, the same goes for satellites.
The video is using quite a slow frame rate as you can see them flickering and the blurring effect as they move is making them appear larger than they would be with a high frame rate.
You may find this article explains it a little more (I can't get it to open properly) I may have a hard copy, will have to have a look.

Re: What is this? (Strange objects in Ha wavelength)
Sorry Alexandra I didn't fully pickup on your post, I went back and read it again and thought Oops.
Your coronagraph is exactly the instrument that shows these things very well.
Wish I could see the video.
The link above does work but very slow so I haven't got to the part where Horace Dall mentions these artefacts.

Re: What is this? (Strange objects in Ha wavelength)
Thanks Rod, Alexandra
That settle this, then. Maybe since I am in middle of a city with a high rises observatory and very little vegetation is why I do not have as much insects/pollens. Thanks again. I learn new thing everyday.

Hi Alexandra
Yep that works.
Just like I remember, loads of these little objects streaming past.
I can't find another video on the net showing this.
Thanks for sorting it,
