  We have applied the method of star counts with Wolf diagrams to determine the
interstellar extinction in five Galactic cirri in Sloan Digital Sky Survey
(SDSS) Stripe 82. For this purpose, we have used the photometry of stars in the
GALEX NUV filter and the photometry of red dwarfs in five SDSS bands and four
SkyMapper Southern Sky Survey DR2 bands. We have identified the cirri as sky
regions with an enhanced infrared emission from the Schlegel+1998 map. The
extinction in them has been calculated relative to the nearby comparison
regions with a reduced emission. The results for different filters agree well,
giving the range of distances and the extinction law for each cirrus. The
distances in the range 140--415 pc found are consistent with the 3D reddening
maps. In the range between the $B$ and $V$ filters the extinctions found are
consistent with the estimates from Schlegel+1998 for the Cardelli+1989
extinction law with $R_\mathrm{V}=3.1$. However, the extinctions found for all
of the filters are best described not by the Cardelli+1989 extinction law with
some $R_\mathrm{V}=3.1$, but by the inverse proportionality of the extinction
and wavelength with its own coefficient for each cirrus. In one of the cirri
our results suggest a very slight decrease in extinction with wavelength, i.e.,
a large contribution of gray extinction. In the remaining cirri a manifestation
of gray extinction is not ruled out either. This is consistent with the
previous measurements of the extinction law far from the Galactic midplane.
