We report than an optical spectrogram of ASASSN-14cl (ATel #6233) shows that it is a dwarf nova outburst, as suggested by Stanek et al. (2014). The spectrum obtained on June 15.0 UT (range 400-680 nm, resolution 0.6 nm) with a 25 cm SC10" telescope and slit spectrograph LISA (R = 1000, 9 x 300 sec exposures) shows a strong blue continuum, narrow component in a broad absorption for H alpha, other Balmer lines in absorption and He II 4686 in emission.

The spectrum can be downloaded from ARAS (Astronomical Ring for Access to Spectroscopy) database using this link. For more information see this link.
