This has been mentioned before on this newsgroup but just in case you
forget - it's on tonight.

Its good to see this kind of material given such prominence on the BBC.
Its
been too long. They've had some superb documentaries and science
programmes
on BBC2 and BBC4 over the last few months.

I've always been interested in space, science, technology and their
impacts
upon our lives. These programmes are helping to fill gaps in my knowledge.

Enjoyed the show last week about the moon. I realise many people ask about
viewing the moon landers but I'm sure I read of some plans to test optical
systems by imaging the craft from lunar orbit. Did I imagine that or is it
still on the cards?

Also, another off the wall question.... I was reading about the
supernova/unusual explosion a week or two back, it got me thinking: how
close would such an event need to be in order to be seen on earth (in our
light polluted cities) by the naked eye. Would we ever see a very close
one
during they daytime?

Odd question, I know but I remember reading about people in China who
documented comets and other space objects visible during the daytime.

S Andromedae 1885 reached 6th mag. This was a supernova in the Andromeda
Galaxy M31, distance 2.2 MLY.

And of course the 1987A supernova in the LMC reached about mag 2-3.

The 1054 AD Crab Nebula SN was seen in the daytime for a few weeks, and
Tycho's supernova of 1572 (year?) was brighter than Venus and I recall that
accounts said it was visible in the daytime. These were in our own galaxy.
