There are some published results of photometric observations of NGC 3808B. Tomov (1978) has found $V\,=\,$14.27 for the 54" aperture which covers almost whole galaxy. This value is more bright than that found by us ($V_{t}\,=\,$14.39) probably because of getting in the aperture the star, located to SW from the galaxy.

Gavazzi et al. (1991) give the results of photoelectric observations of NGC 3808B with three various apertures. The mean difference between these values and our measurements for the same apertures is $\rm -0.05\pm0.02\,(\sigma)$. In the work of Gavazzi & Randone (1994) the apparent magnitude in the $V$ band within the elliptical isophote of 25 $\rm mag\,arcsec^{-2}$ is given: $V_{25}\,=\,$14.61. Taking in mind the mean difference between their $V_{25}$ and total magnitudes in RC3 ($\rm +0.3\pm0.2$) we make the conclusion about good agreement between our $V_{t}$ value and the data of Gavazzi & Randone (1994).

The isophotes of NGC 3808B in the $V$ band are given in Fig.2. The main body of the galaxy is viewed practically edge-on. The twined arm become apparent as “swelling” of
