Read moreWilliam Sadler Franks (1851-1935) was astronomer-in-charge at F. J. Hanbury’s private observatory at Brockhurst, near East Grinstead, Sussex, from 1909 until his death in 1935. This paper reviews the observational projects Franks undertook at Brockhurst, including his work on double stars, red stars, diffuse nebulae and dark nebulae, as well as his involvement with the commissioning of a 24-inch reflector built by Thomas William Bush.
Read moreThe results from multi-station observations of the 2013 Perseids meteor shower are presented and discussed, including an estimate of the Perseids’ population index.
Read moreBAA observations between 1995 April and 1996 February are reviewed. Highlights of the apparition were observations of the phenomena of the triple ring-plane crossings by the Earth and the ring-plane crossing of the Sun, the results of which show that the predicted times were correct to within a few hours. Transits and shadow transits of Titan, Rhea, Dione and Tethys were observed. Several mutual satellite events were also observed, either visually or by means of CCD cameras. White spot activity could again be followed in the planet’s northern Equatorial Zone (EZ), though it was much reduced from 1994-’95: the long-enduring white spot (WS1) had survived solar conjunction and continued to move with a rotation period close to 10h 22m, as did another short-lived feature…
Read moreIn 1839, Ebenezer Porter Mason (1819-1840) produced detailed drawings of the Omega Nebula (M17), the Trifid Nebula (M20) and the eastern part of the Veil Nebula. This paper reviews his life and his observations, comparing his results with those of the modern amateur astronomer.

This mentioned the involvement of the radio astronomy community in a study of radio propagation conditions a few days either side of the 1927 total solar eclipse.
Read moreA brief note in relation to a strange lighting effect captured during sunrise over the Cichus-Weiss region of the Moon by Thomas Gwyn Empy Elger in 1888. A comparable observation made by the author in 2009 is discussed and assessed against recent CCD imagery. These comparisons confirm that the effect which led to Elger’s report is repeated under comparable conditions, and his original hypothesis in relation to the nature of the feature can now be clarified.
Read moreA biographical sketch of the first Director of the Association’s Lunar Section, Thomas Gwyn Empy Elger (1836-1897). His diverse contributions to lunar studies are placed in context and reviewed against the backdrop of developments and advances in the subject during his lifetime. The methodology he consolidated and developed for amateur selenographical work during his Directorship is also discussed in relation to current studies.
