Post subject:  Bolton School Visit -- 9th May -- Mercury Transit

Plans have been put together for members to support Bolton School in observing the Mercury transit across the sun. As it stands we will be in the same car park as we were for the Solar Eclipse of 2015 setting up around 11:30 am.

Ross will be giving a talk on the 3rd of May as to what to expect but it’s been calculated that first contact will be at 12:12 lasting around 7 hours. Depending on the weather we'd observe as much as we can while assisting the pupils with observations.

The usual rules apply in that don't stare at the sun directly and use solar filters where applicable but should be a good event especially if it’s clear.

Forecast is looking very hopeful for Monday!

Just a reminder - it is the Dobson Road entrance. This is security gated but Louise will be there at 11:30am to let BAS members in. If you can endeavour to be there for as close to half past as possible this will be a big help.

The car park is on your right as you come in. Park up at the top end to leave the main area clear for telescopes.

We are aiming for around 2 hours of viewing so leaving just after 2:00pm.

We should have a great selection of telescopes including being able to see the event in stereo with 2 eyes.

If you are bringing a telescope make sure it is 100% safe for solar viewing. I will be checking.

Should be a great day and remember the Sun cream!

Thanks to all those who came along today to Bolton School. Probably the hottest BAS event we have ever had!
We even had mobile catering - thanks Dave. I think we just had about every option for observing the event. Webcams, YouTube, white filters, orange filters, hydrogen alpha (3) and 8 inch binoculars. Wow. Great team effort.

The next one is 2019 but is in November and the UK is not best placed for it - only partially visible at sunset so this was the one not to have missed.

Certainly not to be missed and thanks to all off those for coming. Again another good turn out from members and positive feedback from the staff of Bolton School.

Looking forward to seeing the pictures, but will anyone get the end of it!

What a brilliant day!
For probably only the second time in history, Lancashire was one of the best places to observe an astronomical phenomenon (the other being Richard Towneley's observation of the 1677 transit of Mercury). And today whilst it's been raining over many other parts of the country, we all got a "transit-tan"!

One aspect which I found more striking in the "white-light" filtered 'scopes than the hydrogen-alpha instruments was how much blacker Mercury's silhouette looked than the nearby sunspots.

Here's a quick preview of one of my images (there's a load more data on the hard-drive!):

And thanks to Carl, Brendan and Louise for organising our visit to Bolton School.
