[BAA-ebulletin 01030] NLC Alert

BAA electronic bulletin

NLC Alert

As of 2019 21 June 22.55UT I have clear skies and NLC in the overhead
and beyond from the Moray Coast. Nothing on the northern horizon
because it is too light. I have had reports already from Sussex. This
should be visible as far south as northern France and could go
further.

Any reports please to - sandra-b@hotmail.co.uk<mailto:sandra-b@hotmail.co.uk>

Cheers

Sandra Brantingham

Aurora and NLC director

BAA Newsletter Issue 26 - June JBAA now available on-line

Brighter Comets, Venus elongations and wandering asteroids
The BAA's latest newsletter

Welcome to the June JBAA, now on line

Demonstrating our growing band of international members the Journal
editor was pleased to place American Adam Block's beautiful image of
the Foetus nebula on the front page.

This month sees another packed Journal hitting our doormats, physical
and cyber, leading with four interesting and professionally written
papers covering the full breadth of amateur astronomy. Johnathan
Shanklin continues with his report of the Brighter Comets of 2014, (84
comets were assigned 2014 designations), Richard McKim presents the
eastern and western elongations of Venus, 2007-17 this time focussing
on the planet's nocturnal hemisphere. John Rogers' series, together
with Gianluigi Adamoli, on Jupiter's North Equatorial Belt continues
and Jean Meeus aptly presents his findings on the very unusual orbit
of the co-orbital asteroid, 2015 BZ 509 of Jupiter.

The President, Callum Potter reports on the new plaque in memory of
Sir Patrick Moore at his old home, Farthings, as part of the Selsey
Heritage Trail. Nick Hewitt has some choice images of the black hole
in M87, Simon Brink in Melbourne, Australia calls for BAA volunteers
to assist Museums Victoria in the restoration of the Great Melbourne
Telescope. Contact Simon Brink at shrink@museum.vic.gov.au if you
think you can help.

Amongst the Sections, Sandra Brantingham, Director of the Auroral and
NLC Section is turning her Section's focus to NLCs as the sun
continues to disoblige us - commiserations to the Solar Section. And,
in this 50th anniversary year of the Moon landings, Bill Leatherbarrow
recounts the story of the relationship between the US Lunar
Exploration program and the work of the BAA Lunar Section. Don't
forget the Variable Star Section's campaign to observe old Nova HR
Lyr.

Richard McKim announces that after 15 years as Director he is handing
over the reins of the Mercury and Venus Section to Paul Abel. Thanks
to Richard for all his excellent work in leading this Section.

Did you know that the International Astronomical Union (IAU)
celebrates its 100th Anniversary in July this year? Coming into being
after the end of the First World War with just 7 members of which the
UK was one, it is now 82 members strong. A year of events is taking
place. Richard Miles attended IAU100 Amateur Astronomy Day in
Brussels and takes us through the day which ended with a star party in
Place de L'Agora in Brussels. Looks like quite a party.

David Arditti writes another of his articles on techniques, this one
helping us to understanding image defects, cutting through the
technical stuff with a plain speaking scythe. In the archives John
Chuter has, amongst other interesting things, recovered the October
1994 JBAA showing the 'carpet bombing' of Jupiter by P/Shoemaker-Levy
9. Look out also for his new series on artefacts from the Archives.
Archive Resources on the Web can be found here including the lantern
slides collection.

With much more in the Observers' Forum, BAA Updates, Letters, and
Meeting reports, there is plenty to read whilst waiting for it to get
dark!

StarLink Satellites

David Arditti kindly drew our attention to the issue of these
satellites recently released by Elon Musk, during his Sky Notes at the
end of the recent BAA Ordinary meeting. You have only to take a look
at the Community Forum discussion to see the consequences that the
passing of these satellites may have on our observing. Nick James and
others have posted various images (see left) and video of their
passing across the night sky. There are also suggestions of how to
deal with them intruding on images....good luck.

Paul Abel and Pete Lawrence - the Winchester Challenge continues

If you didn't catch Saturn and Pluto together on 1st June when they
were just 3.3 degrees apart, then there is always the next observing
opportunity which is to observe the variation of Iapetus, the third
largest moon of Saturn. With its two-tone surface it appears to vary
in magnitude during its orbit. It's a good time to get started now
and try and catch it at various intervals in its orbit.

Latest Section Circular from the Variable Star Section
Hot off the BAA Website is the latest circular from the VSS. It is
now available to download. This is the last one from Roger Pickard as
Director, a position he has held for a remarkable 20 years. Taking
over is Jeremy Shears, but Roger will continue as Assistant Director.
Great work Roger.

And Also the Lunar Section Circular

This one will be live on this link in a few days. It leads with the
exciting news that the IAU has officially named Minor Planet TG12
after the BAA lunar domes coordinator Raf Lena. It is a main belt
asteroid and will now be termed '102224 Raffaellolena'.
