Title: Venus transit 5 June 2012
Post by: The Thing on Feb 21, 2011, 22:01:19
I just read about this in the US Astronomy magazine. It would be good to organise a transit event if its visible in the UK. Won't be another for a century!

Duncan,

I think this is only visible from the Pacific region.  :(

It's not supposed to be visible from this country but we had our turn in 2004.

Its visible from most of the globe, just the part thats in daylight,

Hawaii looks most suitable.

Thought that might be the case. Looks like a long haul holiday might be in order.

The transit (http://www.hmnao.com/nao/transit/V_2012/) will be visible from London, at least the very end.

Otherwise it's Hawaii or Tahiti or Tonga or Bora Bora... and it's my 50th that year AND the wife likes the idea. Dear oh dear, better start saving.

Seemingly the longest visible transit will be seen from southern Iceland, which isn't too far. Technical Details (http://www.transitofvenus.nl/details.html).

I have been out to scout a site for observing the transit. I have decided that  Joss Bay, Broadstairs (http://maps.google.co.uk/maps?q=51.379047,1.445956&hl=en&num=1&t=m&z=17) is ideal. It has a north to north east facing cliff edge car park that is tarmacked to a position far from the main part of the car park and the road. The car park has no barrier.

As long as the weather is totally ridiculous I will be there for the Wednesday morning sunrise as I will never get another chance to see a transit of Venus and even a glimpse will be worth it.

Post by: Carole on May 20, 2012, 22:45:43
It's possible I am going to be in Penzance on that day, but I guess being further west I will stand even less chance of seeing it.  I saw the previous transit at Greenwich and saw the full works, so not too disappointed if I miss this one.

I'll take my eclipse specs with me though on the off chance.

It will be visible after sunrise on the 6th June as long as you have an excellent view of the horizon (and the sky is clear).

Next chance to see one will be in 2117.

Just looked at the planetarium software.  At 4:30 GMT  (5:30 BST,  6:30 European time) Venus starts to move off the sun's disk.  The sun is only 5degrees above the horizon at this time.

My suggestion is to find a high point with little likelihood of mist or haze at the horizon.  Joss Bay might suffer from sea mist.

My plan is to consult the weather forecast the evening beforehand and then drive to a likely viewing point to arrive before dawn.  This is what I did for the total eclipse in 1999 - I ended up having to catch a last minute ferry to France to drive to the only patch of predicted clear sky within easy reach!  I did manage to see the total eclipse  8)

I attempted to get to St Malo but wasn't feeling well so kept stopping for a sleep.  I reached the general area and although there were breaks in the cloud, they weren't enough to allow me to see anything.  So a disappointment.

Got up at 3:30 GMT, already had the car loaded with gear, scopes mounts and the like. The sky was not looking very promising. I did consider changing my mind on the location as the cloud breaks were due in the west first, but decided to stick with my origional plan of Kings Standing on the AshDown Forrest. Got there about 3:50 GMT  a father and son were already at the car park and had been there of 30 minutes but reported that the cloud had been about the same. That is completely clouded in. Set up the scopes, th eLunt and William Optics 66 then waited. The cloud was very fast moving, which gives a chance at least. A few small breaks came over but didn't go where they needed to. Then the radio mast at the police training centre was hidden by fog. Only 20 minutes to go, then a small break which was followed by a very promising larger one. We waited for it to move across and reveal the Sun. We saw the black circle of Venus nearing the edge of the sun, only to be covered by cloud again. Another break rolled overhead this time larger than before, would it reach the point where the sun was before the end of the transit. It did I had planned to image using a webcam but it would take too long to set up, I remembered I had thrown in my DSLR and tripod at the last minute, grabbed them and quickly set up, took the molar filter off of the 66 and took a couple of shots. I had forgotten that the auto focus would struggle with the low light so the first shot or so were completely out of focus. Manually focused and took a few more shots, they were over exposed, so manual focus and manual exposure, and sucess. Well at least I could see Venus sharp, leaving the Sun's disk. That was it as the cloud rolled back in to hide the remainder of the transit. 

Looking forward to May 9th 2016 for the transit of Mercury. http://www.venus-transit.de/Mercury2016/index.html

Hi guys and gals, some fascinating posts here on the venus transit and great pictures on the web. But I am trying to find (reasonably) accurate 1st, 2nd, 3rd and 4th contact timings for the june 2012 transit as seen from at least two distant locations in the world. I can't find any anywhere on the web. I am (sad man that I am...!) trying to replicate the calculations of 1760s that first gave us the size of the solar system from venus transit data. Perhaps nobody bothers with this any more since we have better ways of measuring the astonomical unit. Anyway, if anyone comes across these timing I would be glad to have them, together with the locations that they apply to. I have emailed both the Sydney Australia observatory and the Japanese national observatory Tokyo, but no reply.

PS I realised the other day that the date of the June 2004 venus transit was my first visit to OAS and when I became a member, so thanks to you all for a great 8 years! Anyone got plans for 2117? (me neither!) - Nigel

I was fortunate to view the transit at the Varsity Stadium of Toronto University along with 5000 others in perfect conditions.  The event was organised by the Dunlap Institute for Astronomy and Astrophysics.  They are exceptionally user friendly.  Here is a link (hopefully it will work) - http://dunlap.utoronto.ca/
Title: Re: Venus transit 5 June 2012
Post by: nigelf on Jul 17, 2012, 09:16:16
Thanks for the replies Mick and Vera. I still await a reply from Subaru. Dunlap replied to say they "did not take any timings, there must be some out there on the web somewhere" - but when they Googled they couldn't find any either! Still no replies from Tokyo or Sydney observatories, but Dr Gareth Wynn-Williams, Professor of Astronomy at the Institute for Astronomy, University of Hawaii found me a set from there! So I now have one set but need at least another. I have an email out to 'Mr Transit', Fred Espenak of NASA. Are any of you guys linked to Greenwich Observatory able to help? Thanks again.

Today's EPOD (http://epod.usra.edu/blog/2012/08/venus-transit-and-distance-to-the-sun-from-earth.html) takes a look at this, but doesn't quite give enough detail (like what care they took to get photos at exactly the same instant). Still quite cool, though.
