  Resolved UBVRI photometry of RW Aur binary was performed on November 13/14,
2014 during the deep dimming of RW Aur with a newly installed 2.5 meter
telescope of the Caucasus observatory of Lomonosov Moscow State University at
the mount Shatzhatmaz. At that moment RW Aur A was $\simeq 3^m$ fainter than in
November 1994 in all spectral bands. We explain the current RW Aur A dimming as
a result of eclipse of the star by dust particles with size $>1 \mu m.$ We
found that RW Aur B is also a variable star: it was brighter than 20 years ago
at $0.7^m$ in each of UBVRI band (gray brightening).
