UV Per: possible superoutburst

On 30 Sep and 1 Oct, we performed short observations 
for UV Per, too (observer: A. Arai & R. Matsui). 
The object is now fading.

The fading speed is about 0.1 mag/day and the V-J color 
is about +0.1. These are typical features of superoutbursts, 
while long time-series observations are essential to 
determine the nature of the current outburst.
