Mercury solar transit.

Mon May 09, 2016 3:04 pm

You can see Mercury crossing the face of the sun on the solar imagery on the NASA space weather site at
http://www.swpc.noaa.gov/communities/sp ... nthusiasts

It is clearly visible in the visible spectrum but a bit harder to spot in the X-ray image.

Thanks! Yes, in the visible spectrum near the end of the clip from 11:30 -- 13:10 UTC ... you can grab the slider and manually position between those times...

That would require the space weather satellite to be farther from the Sun than Mars is. Last time I checked, the space weather satellites were all inside Earth orbit. (It kind of helps to see solar events *before* they hit the Earth.)

Yes you are correct on all points. However you will "see events" before they reach the earth anyway as the particles that cause trouble all travel slower than the speed of light ! :shock:

That's not the point. If the weather satellites are all in orbits of less than 1 AU from the sun, how can Mars, with an orbit of around 1.5AU pass between them and the sun?

This may be Venus or Mercury, but it seems unlikely that it is Mars unless there's a space weather satellite out by the asteroid belt.

Is a beard a requirement for this particular thread?

The entire transit may be seen now from about 11:30 -- 18:50 UTC... very cool.

What I would really like to see is the Pluto (still a planet in my world) transit. I would suffer through growing a beard to see that!

So you are out past Pluto looking back at it as it goes across the face of the sun? Isn't the sun rather a pin prick of light at that distance? And even if you magnify it, don't you then have to be significantly farther away from Pluto than Pluto is from the sun? So, basically, you are on that nano ship to Alpha Centauri realSoonNow?

I've just realised I got the wrong "M" planet ! It was Mercury , not Mars !

Sorry for any possible confusion that caused ! W. H. Heydt's comments make more sense now ! Sorry again.
