Abstract
NGC 4314 is a strongly barred spiral galaxy with an inner ring, having the peculiarity of a conspicuous nuclear spiral structure inside the ring [see the Hubble Atlas (Sandage 1961) p. 44]. The ring is optically sprinkled with hot spots. Radio-continuum emission has been mapped at 2-, 6-, and 20-cm with the VLA by Garcia-Barreto and Pişmiş (1985): the nuclear ring is obvious (Figure 1) and highly contrasted, revealing non-thermal and thermal emissions. H I emission was observed at Arecibo (3.3 arc-minute resolution), but only a very weak H I mass was derived of about a few 106 M ⊙ (Figure 2). This is probably related to the smooth and featureless appearance of the bar and outer arms of this galaxy, classified as anemic by van den Bergh (1976).
