Abstract
THE Leicester University Sky Survey instrument with its field of view perpendicular to the spin axis was able to continue the study of A0535+26 after the spin axis experiments (see accompanying papers) were manoeuvred away on April 29. The source was close to the centre of our field of view on May 2, May 19 and June 1. On the first occasion the instrument was in a single channel mode (no spectral information) but eight-channel spectra between 2 and 18 keV were obtained on the second and third observations.
