Abstract
Observations have been made in the direction of the old SNR S 147 with the X-ray satellite Exosat. No emission was detected with the low-energy experiment, constraining the SNR parameters (energy and ambient density) for a Sedov model or a radiative one. A weak source was detected with the medium-energy experiment which could be associated with the SNR, although the transient pulsar A 0535 + 26 may contribute significantly in this range.
