THE RADIO, OPTICAL AND X-RAY-PROPERTIES OF THE RADIO-SOURCE-0927+352

The radio structure of the source 0927 + 352 (87GB 092752.8 + 351642) consists of a highly variable compact core and an extended diffuse hal o, and comparison of its mas-scale and arcsec-scale structures suggest s a twist of an internal jet and strong projection effects. Its optica l counterpart varies by about 2 mag and shows no hint of emission line s in its spectrum. A mean time-scale of radio variability of about 6(- 2)(+4) yr and a mean time delay between optical and radio 'events' of about 4 yr are suggested by collected data. X-ray emission from 0927 352 was detected by the ROSAT satellite, and we report on its X-ray s pectrum. 0927 + 352 is probably a rather slowly variable BL Lac, altho ugh it could be a QSO with very weak emission lines.
