Stuff that occurs to me

All of my 'how to' posts are tagged here. The most popular posts are about blocking and private accounts on Twitter, also the science communication jobs list. None of the science or medical information I might post to this blog should be taken as medical advice (I'm not medically trained).

Think of this blog as a sort of nursery for my half-baked ideas hence 'stuff that occurs to me'.

I think I need a bit more information for ISS passes

There's an ISS pass coming up at 21.45pm tonight but I seem to be missing either a bit of information, or the skills to understand the info below.

It's easy if the ISS is passing over close to 90 degrees as I just look West and look directly up and I'll see it. But the lower the degree value the further away it is from 'straight up' - but on which side? I know there are other sites on the web where you can get more information about length of transit and the arc it will sweep, but I don't think there's quite enough info below, especially if the ISS pass was at 23 degrees say. Or am I just being dense?
Is it a good one?
This time, the International Space Station will be flying over at 55 degrees. Its magnitude will be -3.2: extremely bright!
Where to look?
ISS will come up at the horizon from the west.
But on which side of the West?

I've drawn a diagram of me happily spotting the ISS (artist's impression, not drawn to scale you understand) at 45 degrees but what if I'd been looking at the other side?

Comment policy: I enthusiastically welcome corrections and I entertain polite disagreement ;) Because of the nature of this blog it attracts a LOT - 5 a day at the moment - of spam comments (I write about spam practices,misleading marketing and unevidenced quackery) and so I'm more likely to post a pasted version of your comment, removing any hyperlinks.

Comments written in ALL CAPS LOCK will be deleted and I won't publish any pro-homeopathy comments, that ship has sailed I'm afraid (it's nonsense).
