SPA ENB No. 334b

I hope to be up for this one if the Skies are clear....

         Electronic News Bulletin No. 334b      2012 July 12

By Robin Scagell

A rare lunar occultation of Jupiter takes place this coming Sunday
morning, 15 July, starting at about 2.50 am BST – so you'll have to
stay up on Saturday night! The Moon will be low down in the east north
east, so you will need a good low horizon in that direction, as well,
of course as good weather!  The event will only be seen south of a line
running roughly from South Wales to Lincolnshire. For many people
Jupiter will just graze the lunarlimb, giving a very interesting
appearance, while farther south of a line between Dorset and Suffolk.
Jupiter will be fully hidden for a time. The map on the SPA webpage
shows these two lines.  Jupiter's satellites will also take part in the
event, and each one has its own graze track across the UK, south of
which it will be completely hidden. As seen from Greenwich, the event
starts at 01.51 UT (2.52 am BST) with Europa, followed by Io and then
Jupiter itself at 01.56 UT. Other timings from Greenwich are shown on the
website below.

Timings for other locations will be just a minute or two different from
these. The event will be worth watching from the whole of the UK, though
north of the line Jupiter will not be hidden by the Moon at all. The
simulations shown on the website are from the free planetarium software
Stellarium, which will give you precise predictions for your own location
should you need them.  More information at:
