Right then,

This time we love Venus behind the moon for a short time. I have missed the last occultations because of clouds but this should be a hopefully good one we all can see as it is in broad daylight. You only need binoculars to see it too, so they are saying.

Check out this link from the Society for Popular Astronomy. While you're at it join the organisation as it is brilliant.

Seems like a bit of a long way to travel, just to make love to Venus. Still, behind the moon is more exciting than behind the bike shed I suppose.

ha ah GT! Spotted my typo!

Reminder that this event is Monday everyone.

Well I have the scope set up but am having difficulty seeing anything with the clouds.

According to Stellatrim free software (www.stellarium.org) Venus should disappear behind the moon at about 4pm our time.

Bloody clouds!

I'll be looking out for this, but same here in Garching - a lot of clouds around.

Just looking at the list of times in the link Jeremy gave. UT is Greenwich Mean Time, right? So adding two hours onto that should give the approx times for Germany. Interesting that the times vary quite a bit between different towns in the UK. Is that an effect of parallax? - the fact that venus is much farther away than the moon, so that even a small shift in the observer's location and hence viewing angle means that you see things differently? I suppose if you were very very clever you could use that to work out the distance to Venus.

Anyway, now I'm confused - the topic subtitle says "5pm-ish CEST Monday 18.Jun.2007", but according to my reckoning (and Jeremy's earlier post) Venus should go behind the moon around 4 pm (or maybe a bit earlier?) and reappear around 15 to 20 minutes later. I'll be looking out for it around 4pm anyway.

Check out Calsky.com. Google in your location. I get 4.20 pm here in Holzkirchen. But I reckon the clouds are going to mess it up!

Well I didnt see the event but the sky cleared a bit later and I was rewarded with my first ever daylight view of Benus. Beautiful. could see what phase it was at. You can't see that at night.
