Extract from RAF Operations Record Book for No. 304 (Polish) Squadron

Transcription of an extract from the RAF Operations Record Book for No. 304 (Polish) Squadron.

This extract from the RAF Operations Record Book for No. 304 (Polish) Squadron gives a summary of events during their brief posting to Tiree in 1942. The daily meteorological observations underline the importance of weather conditions for flying operations.

During their month on Tiree, the squadron carried out seventy-nine anti-submarine sweeps over the Atlantic in Wellington aircraft and dropped depth charges on six possible sightings of U-boats. They also reported on the position of convoys and other shipping.

The Wellington aircraft, however, lacked sufficient range over the Atlantic and the squadron was transferred to Wales, from where it began operations over the Bay of Biscay

The Campbell-Stokes sunshine recorder was invented in 1853 by John Francis Campbell, the editor of ‘Popular Tales of the West Highlands’, and modified by Sir George Gabriel Stokes in 1879. It consists of a glass sphere, about ten centimetres in diameter, mounted on a metal stand.

Manufactured to Met Office specification, the glass sphere focuses the rays of the sun to an intense spot which chars a mark on a curved graduated card mounted concentrically with the sphere. As the earth rotates, the position of the spot moves across the card. The card is held in place by grooves, of which there are three overlapping sets, to allow for the height of the sun during different seasons of the year.

Its main advantage is its simplicity and ease of use. However, the results require interpretation by an observer and may differ from one person to another.
