In this clip there are 4 bright dots moving to the right and one slowly moving to the left - pretty much the entire clip.

I think Earth and Venus are moving right and Mercury to the left.  If that's right, what are the others? I don't see any other candidates at http://secchi.nrl.navy.mil/STEREOorbit/McNaught.html

You correctly identified Mercury, but the four bright dots moving right are actually stars, you can tell because they move exactly with the rest of the star field. 
Stereo B could only see Earth for a very short time at the beginning of the mission, both it and Venus tend to be a fair bit brighter than those stars. :D

Thanks Quiallis. Good to know about star movement - makes perfect sense. I really like checking out solar system movement on the Orbit Viewer.

A nice end to tis clip. Here I go guessing again..Venus and Mercury? What are the other dots? It looks like something with moons. I have to dash right now so cannot check the orbit show-er (techy talk). Will revisit later on though.  ;D

I am guessing the lines in the stereo behind in this incoming video are planets.

Hi Dean, I wanted to see if I was using the viewer correctly, so looked this up.  As far as I can see it's Mercury.  Question...when using orbit view to identify comets, do you have to search each group separately?  As far as I can tell, there's no way to just plug in a date and it show you the system at that time.  I hope I'm missing a step, it sure would make things easier.

It's raining!!! Finally.

Hi lolinda,

do you mean the SECCHI viewer? Actually, that's just what it does:

Just hit the "Date" button, and you get a pop-up window where you can choose the date (see attached pic). You might not see the little window right away, coz it opens in minimized mode. You need to look for it in your task bar.

cheers

You guess right! :)  For real time data you can use this page(scroll down to the HI1 images) to identify suspect planets.  Also, I think the rightwards moving dot near the bottom of Ahead is Mercury, it's out of the frame already by the end of the video so it isn't on the labeled images.

The orbit viewer we're using to identify planets isn't really helpful for identifying individual comets.  You could narrow it down to what group the comet is in by comparing the path of the comet in the video to the orbit of the group, but if you want to identify it's name/number, you're going to want to look at this list:  http://www.rkracht.de/secchi/comets.htm

Hi everyone. New to this place and just saw this video.
http://solarstormwatch.com/favourites/2622 20070109
It's the first one I've seen that isn't the standard view of the sun, I was kinda surprised by it!
I take it the loop starting at around 8.00 is from Earth. What do you think?

Hello
I'm not sure, it's Venus (the bright in front) and Mercury (small from 00:00 to around 12:00, moving from 6'clock to 4) in the video?

If I'm correct, the site you recommend for is good (http://secchi.nrl.navy.mil/STEREOorbit/McNaught.html)

What is the spreading wave coming from Venus? I saw one of those in one of the videos I was rating, but couldn't find a way to switch it to "what is that?". It looks like Venus is emitting a flare.

Hi andrewes
that is an optical effect.
Welcome to SSW !  :D

OMG! It exploded! LOL

Great view of Venus as seen from Stereo Behind, and it makes a spectacular exit from the frame.

Just found two cool videos, one with Venus, Saturn and Mars, the other with Jupiter and Mercury

Has anyone seen four planets at once?  I'm not sure if there are any times where there are four planets visible in the HI1 field of view since Stereo launched, but it would be really cool to find them if there is...

Was just wondering if the planet in the video would actually be Mercury or Venus. The planet's orbit kind of seemed to go to the right and slightly upwards, before starting to turn back and move to the left?

I would suppose the planet should be of inferior orbit to that of the Earth since we are actually seeing it changing its course?
