Section Director David Arditti introduces the new Equipment & Techniques Section, and reports from the Mars, Saturn and Comet Sections highlight the planetary observing skills of BAA members.

Define the size of an asteroid with amateur observations, travel back in time to the BAA in the 1970s, and find your way around the spectacular dark nebulae of the summer sky: plenty for all in this Journal

Here is Jeremy Shears’ second Presidential Address, and a description by our Jupiter Section Director John Rogers of the remarkable patterns of cyclones discovered at Jupiter’s poles by the Juno spacecraft in orbit around the planet

Here is another of Martin Mobberley’s inimitable biographies of one of the more eccentric personalities from the BAA’s past. And the truth about the British Empire Medal awarded to one of our former Presidents, Howard Miles – a truth he kept secret for all of his long life

Don’t miss Tim Haymes & Alex Pratt’s report on the recent occultation by Triton, seen from the UK by at least 11 observers, and from elsewhere on the track by many more. Jon Shanklin fills us in on the prospects for next year’s comets, and Peter Birtwhistle imaged the so-called ‘interstellar asteroid’ A/2017 U1 from his home observatory at magnitude 22…

Here is part II of John Rogers’ seminal study of Jupiter’s South Equatorial Belt cycle in 2009-2011. We also show some amazing images by BAA members from the 2017 August 21 total solar eclipse, and Paul Abel’s ‘Absolute Beginners’ tutorial no. 11: ‘Astronomical Seeing’

A bumper issue with five fine observational papers presenting the work of BAA members worldwide; Damian Peach shows how to capture the galaxy’s most remote and obscure globular clusters, and Mike Kretlow from IOTA-ES describes a stellar occultation by Triton in October, observable from the UK, Europe and the eastern USA

Four comets observed from Winchester, full details of the 2009 SEB fade on Jupiter, and a historical note from one of our oldest members…

Amateurs observe a bright spot on Neptune, and BAA observations of Venus & Saturn. And how to see the 2017 solar eclipse from the British Isles! (but only just)…

In this issue we have the 2016 Presidential Address, and a fine historical paper about Eliot Merlin of Merlin Medal fame. And why not have a go at the ever-popular ‘Messier Marathon’?
