Observations of the x-ray source A0535+26 by the Sneg 2 MP instrument on the Prognoz 6 spacecraft are reported. The source was monitored both in its quiescent state and during a flare. The x-ray light curve for 1977 December 8--31 is given. Flux densities and energy spectra are determined for radiation in the 27--132 keV energy range, where the source would have a luminosity L/sub x/approx. =2.7 x 10/sup 36/erg/sec if its distance is approx. = 1.5 kpc.
