LASCO 72 Hour Video Sun Grazer
https://www.solarham.net/lasco.htm
Watch the past 72 hour video from LASCO C2 above. I’m not seeing anything that matches up to this bright object grazing our star on SkySafari. New comet?
It enters the LASCO C2 frame at 20210127 04:12 and exits at 20210131 10:00

Re: LASCO 72 Hour Video Sun Grazer
I'm possibly missing something here Christopher, but I suspect the item referred to is likely to be a planet, as most of the comets that I've seen in the past via the LASCO C2 images show comets with their dust-trails/tails...
Those planets can be verified using a planetarium program for the relevant dates/times... Possibly known comets too...

Hi Terry,
Thanks for the reply. Before I posted I checked SkySafari and "played" the same timeline with all solar system objects visible. Jupiter is indeed in the neighborhood but its apparent motion is nothing like this object. It is awfully bright and the transit through the field is very steady and slow moving. Not sure what we're looking at. Hoping others will weigh in

Re: LASCO 72 Hour Video Sun Grazer
Just thought of something I hadn't before. I wonder if the apparent motion of Jupiter would be significantly different from the vantage point of SOHO than Earth. It is at L1 which by my limited understanding should not present a different apparent motion from our own vantage point.

Re: LASCO 72 Hour Video Sun Grazer
Hi all...
I looked at objects near the Sun on TheSky desktop planetarium and it shows Jupiter a little over 2 degrees west of the Sun. It will have a slightly different view from a Lagrange point but it is the most likely object in the LASCO animation. Saturn is 7 degrees to the west so it is out of the field of view.

Re: LASCO 72 Hour Video Sun Grazer
Agreed that Jupiter is a very-likely contender as it is well-bright enough for the SOHO camera to acquire compared to the fainter stars.

Re: LASCO 72 Hour Video Sun Grazer
I tend to agree on Jupiter. I suspect the apparent motion animation in SkySafari at that zoom level that close to the Sun is probably not accurate. Now we just need a 72 hour total eclipse so we can test that theory

Re: LASCO 72 Hour Video Sun Grazer
That is really interesting, I didn't realise that Jupiter would move so fast and move round the Sun in 72 hrs, I somehow expected that it would take a few weeks as it moves so slowly across our sky. Maybe it is all about scale.
It could of course be an alien ship as well

Re: LASCO 72 Hour Video Sun Grazer
An Interesting answer Alexandra, but the animation is not being taken from Earth and as far as "alien ships" are concerned -

Re: LASCO 72 Hour Video Sun Grazer
Alien ships...ssshhhh, or they will come for you having let the secret out
If we look forward to a few days centred around March 24th, Venus will pass a little over a degree south of the sun as it passes superior conjunction and should show in the LASCO images.
