141 Radio Sources (Surveys, etc.) 141.001

G 179.0+ 2.7, an unusual galactic radio source? E. Furst, W. Reich. Astron. Astrophys., Vol. 154, No. 1/2, p. 303 - 307 (1986). Radio continuum observations of a new nonthermallarge diameter source in the galactic anticentre direction are reported. It consists of a nearly circular shell-like structure with a diameter of ~ 70' and radial magnetic field, possibly a supernova remnant. At the centre a polarized, nonthermal triple source is seen. It might be extragalactic, but an association with the extended emission cannot be ruled out. 141.002 A radio continuum survey of the northern sky at 1420 MHz - Part II. P. Reich, W. Reich. Astron. Astrophys., Suppl. Ser., Vol. 63, No.2, p. 205 - 292 (1986). The second part of the Stockert 21 em radio continuum survey of the whole northern sky is presented (see 03.141.085). These observations cover the area Oh ~ cx so ~ 24h and -19° ~ Iiso ~ 24°. The results are given in the form of contour maps. The effective resolution of the survey is about 35', while the effective sensitivity is about 50 mK TB (full beam). 141.003 Erratum: "Precise optical positions for radi%ptical astrometric sources south of I) - + 12°" [Astron. Astrophys., Suppl. Ser., Vol. 58, No.2, p. 193 - 196 (1984»). C. Torres, H. Wroblewski, E. Costa. Astron. Astrophys., Suppl. Ser., Vol. 63, No.3, p. 603 (1986). See Abstr. 38.141.016. 141.004 Multifrequency radio continuum observations of extended galactic objects. I. Nine objects from the 2695 MHz Effelsberg galactic plane survey. W. Reich, E. Fiirst, P. Reich, Y. Sofue, T. Handa. Astron. Astrophys., Vol. 155, No.1, p. 185 -192 (1986). The recently published 2696 MHz galactic plane survey with the Effelsberg 100-m telescope has been inspected for extended, unidentified objects. Nine of these objects have subsequently been observed at 1420, 4750 MHz and 10 GHz. Based on the available continuum radio data, the authors propose the following most likely identifications: two supernova remnants, five H II-regions, one radio galaxy, and one object resolved into an H II-region seen in front of a supernova remnant. 141.005 A radio survey in the Origem Loop region. V. V. Vitkovskij, N. A. Nizhel'skij, S. A. Trushkin. Soobshch. Spets. Astrofiz. Obs., Vyp. 48, p. 61 -79 (1985). The regions near the possible supernova remnant PKS 0607 + 17 have been investigated. This extended source may be a part of the Origem Loop - giant ring-like feature in the radio continuum emission. Observations have been carried out in the region from 5h50m to 6h30m in R.A. and from 16° to 18° in Dec. About 50 sources have been detected in this survey. Most of the compact radio sources were identified with the sources from the Texas survey at 365 MHz. The distribution of spectral indices of the sample is normal with the mean value of O. 7.
