Just a thought...

Would anything be gained by taking a IR photo of A51?

Or any other wave lengths for that matter.

I can't really say why it would - just that it may be worth a go.  It,
may show something emanating from the site, that could give a clue to
something.

Yep - thats a lot of IF's :)

Another - totally impractical thing I'd like to do.

Use my own RADAR at A51 - how long I'd last doing it - well, not long
probably!

PS - I don't have my own RADAR btw...

I shot Groom Lake using near IR film and didn't see anything
significant.

You will need Irfanview and the djvu plug in. Refering page is

Note this was a day shot. IR film doesn't let you see in the dark. That
is a misconception. I haven't tried shooting in IR at night to find hot
spots.

This is a quite long exposure test shot I did. I didn't even bother to
clean up the film since there was little info on it, so don't mind the
dust:

Lastly, here is some night vision video:

Hand held, again, just an experiment.

What I haven't done is long time exposure with low contrast Kodak
Portra BW400 film.  I shot a Vandenberg missile test from the Nellis
ranges using this film:

At the very bottom is some analysis using low contrast B&W film using
images taken from the power line overlook.

Lastly, on this page

you can find some night vision photography of the camo dudes.

I think the only technique worth investigating is the Portra B&W 400
film with long time exposure. The film is very low grain, and don't
bloom significantly on bright objects when overexposed.
