[en] Positions relative to AGK3 with an accuracy of about 0.1 arcsec are presented for 69 radio stars observed with the 26-and 13-in refractors at RGO. Independent proper motions of these stars have been obtained wherever possible. Comparison is made with optical and radio positions given by a previous author. (author)

[en] Radio maps of the Seyfert 2 galaxy Markarian 3 have been made with the Very Large Array and the 5 km telescope at 4.9 and 15.4 GHz, each with resolution near 0''.5. The source is an asymmetric double of separation 600 pc, apparently straddling the optical nucleus. We speculate that the double source has been ejected from the inner nucleus (< a few pc) in a process analogous to that responsible for powerful double radio galaxies and quasars

[en] The radio source CL 4 in the Cygnus Loop may have been wrongly identified with a 17sup(m) starlike object; otherwise it is a member of a new class of sources showing measurable differences between radio and optical positions, in this case amounting to 2secs.4. (author)

[en] A deep IIIaF plate has been obtained at the prime focus of the AAT which shows the candidate star described by previous workers near the timing position of the binary pulsar 1913+16. Our astrometry shows that this star does not coincide with the timing position. High-speed photometry of the candidate shows no evidence for pulsations down to a time-averaged R magnitude of 26.5.
