ABSTRACT:Radio continuum and H I 21-cm line observations of the galactic nonthermal object, G 18.95-1.1, are discussed.
The object has a spectral index of
-0.28 between 57.5 MHz and 10 GHz.
Based on its morphology and spectral
characteristics, G 18.95-1.1 is classified as a composite supernova remnant.
H I line
data show a depression in antenna temperature of the extent of the object at
18 km/s giving a distance of 2 kpc.
