[vsnet-alert 16017] ASASSN-13bq is indeed a dwarf nova (ATEL)

[Taichi Kato]

   ASASSN-13bq is indeed a dwarf nova.  The object is most likely
an SU UMa-type (or even WZ Sge-type).  Time-resolved photometry
is encouraged.

We observed the transient ASASSN-13bq (ATel #5209) on UT 2013 July 16.98
for 17 minutes with the FRODOspec spectrograph mounted on the robotic 2.0m
Liverpool Telescope (LT). We obtained two simultaneous spectra, one covering
the wavelength range 390-570 nm with R=2600, and one covering 580-900 nm
with R=2200. We detect a blue continuum with H-beta and H-gamma seen in
absorption at z=0. H-alpha is undetected. These features are indicative
of a hydrogen-rich dwarf nova in outburst. 

ASASSN-13bq was seen again by ASAS-SN on UT 2013 July 18.5 with V=15.5,
compared to V=15.1 on 2013 July 16.6.
