Been looking for it for a while - be nice if we could get some actually clear skies, been misty/foggy here which with background light pollution is making it a sod to spot.
Beautifully clear here last night, just a small smudge through x20 binoculars. Sounds like it may brighten over the next couple of weeks, just in time for the Moon to pop up and ensure it remains a smudge!
You never know though, best of luck peering through the fog!
One guy had a go at explaining it, in a qualitative way (negative electrons moving through a slightly flexible lattice of positive ions, each electron draws some positive charge towards itself and that clump of positive charge attracts other electrons - so two electrons can be drawn to the same place and will appear to have ‘paired up’ as long as everything’s cold enough that thermal vibrations don’t jostle them apart).
I think Bragg’s response consisted of the two words “Oh, God” .
