1927: a British eclipse ... R. A. Marriott
The total solar eclipse of 1927 June 29 was the first to be seen over the British mainland for 203 years. It caused nationwide excitement, induced mass population movement to the towns, villages, moorlands and offshore waters of Wales and the north of England, and severely tested the country's transport and communication systems.

The 'jamjar' magnetometer, sixteen years on ... R. J. Livesey
This paper reviews some sixteen years of experience in operating a simple suspended magnet ('Jamjar') magnetometer. (3 pp)
Intensity variations of Venus' terminator region ... Peter Wade
Variations in the estimated visual intensity of Venus' terminator region are shown to be of the form expected when light is reflected from a rough surface. Additional variations are discussed, particularly in relation to the elevation of the planet in the sky at the time of observation, subjective factors and the structure of Venus' upper atmosphere.

Simple photometric observations of BR Canum Venaticorum (a troublesome comparison star) ... Kevin West, John Howarth & László Kiss
During the last four years an Optec SSP3 photometer has been used to obtain lightcurves for various suspected and confirmed variable stars. Upon analysis the semi-regular variable BR CVn (formerly a comparison star for V CVn) showed clear periods of 712 and 71 days, both periods having average peak-to-peak amplitudes of less than 0.3 magnitude. The total observed range using a V-band filter has been 6.47-7.17. (4pp)
