The instrumental magnitudes at 220 and 342 nm at outburst were 15.4 and 16.2, respectively. Observations of the same object made a year before and 2 weeks later gave an instrumental magnitude at 200 nm of 19.5 and 19.3, respectively. The continuum spectrum of the nova at outburst in the 195-370 nm range can be reasonably well fitted by a power law with an index of 2.3. These characteristics are all consistent with the hypothesis that V2 is a dwarf nova, the first clearly identifiable object of this type in the core of a globular cluster.
