Details of other comets seen during the year may be found on the Section web page, though they have not been analysed to the same level.

We report photometric and spectroscopic observations of the 2014 eclipse of EE Cep. This proved to be one of the shallower eclipses on record rather than one of the deepest as predicted.

Harold Knox-Shaw worked at the Helwan Observatory, Egypt, from 1907 to 1924. The Observatory was equipped with a 30-inch (76 cm) reflector that was financed and constructed by the Birmingham industrialist, John Reynolds (1874-1949), to benefit from the clearer skies and more southerly latitude compared with Britain.

A fireball over central Scotland on 2013 October 14
On the evening of 2013 October 14 several fireballs were reported over the British Isles. One was observed and imaged at 20:42 UTC over central Scotland and is notable for the smoke trail it deposited in the upper atmosphere. This trail persisted for at least 13 mins. and its evolution was recorded in a series of still images. This paper details the observations and provides an analysis based on the available imagery and witness reports. The possibility of a near simultaneous fireball over the Irish Sea is also discussed.
