[vsnet-alert 12822] SDSS J133941.11+484727.5 : spectroscopic observation at KAO

[Akira Arai]

We performed optical spectroscopic observations of SDSS J133941.11+484727.5
on Feb.10 using 1.3m Araki telescope and our low-resolution
spectrograph (LOSA/F, R~550).

Our preliminary spectrum shows a prominent emission for the H-alpha in
its broad absorption component.
H-beta, H-gamma, H-delta and He I (4471A) shows broad absorption
lines. These spectral features also indicate
that the object is a dwaf nova as already reported in vsnet-alert
12807, 12816, 12817.
The Bowen complex of NIII, CIII are possiblily detected, but He II
(4686A) is not seen in our data.

Our spectrum is shown in the following page:
