Stargazing

[Ymx]

You are deliberately being annoying. However, my kind of annoying …

The sun from Mars is 66% of the size from Earth
The earth from Mars is 36% of the size of Venue from Earth

So the net effect is 55% smaller spec over the sun than that picture.

If we take in difference of diameter of the 2 planets which is negligible, earth a tiny bit bigger.

It is 58%

[Ymx]

However, that would be 58% of the width of the relative speck.

So the impact on the area of the speck is actually 34%

[Ymx]

Homers Venus from Earth (I assume)


And a pretend one of Earth from Mars


Well … that’s useless to illustrate the 58%/34%

In fairness one is fake. The real one has light and Len’s effects impacting it.

Spectacular Aurora overnight. A shot from my all sky camera from, just inside the M25, North of Woking

Aurora over London again last night!

[Enzedder]

Can you see them with the naked eye Homer? We are only seeing it with a long exposure setting on the cameras

Just a very red sky here in South Wales, much better with phone camera, will pop some up later..

I've seen some great shots taken in Edinburgh, my wife went up to Braid Hills for a half hour but there just a bit too much light pollution.

We're off to the Cairngorms tomorrow and hoping the northern lights re still active, will be a lot clearer from there. I'm also packing the telescope I bought from the Observatory in Dundee, despite my initial reservations it's actually not too bad:

The NOAA does an aurora forecast, or rather two forecasts. One is a prediction based on solar activity, the other is a thirty minute forecast based on observations from a satellite at the L1 LaGrange point (where the earth and Suns gravity cancel out).

Tonight’s prediction based on activity is not as intense as last night unfortunately, but still might produce a show.

Nice shot

First view looking north east..



Midway looking north..



At the end looking west..

Tried last night, but too much light pollution here

Increased solar activity at the same time as global warming is not a good thing for the planet.

Hello Marjorie..

Increase solar activity at the same time as global warming is not a good thing for the planet.

Sigh.

This is not any kind of activity that leads to warming.

Someone posted this from Waipapa Lighthouse - bottom of the South Island (last night). According to them it was only a 1.5 second exposure
