CR Boo outburst We have found that CR Boo started a new outburst by tonight observation at Kyoto. It seems to be about 13.5mag, which is relatively bright and may indicate its superoutburst nature. The last superoutburst occurred about two weeks ago. If the current outburst turns out to be a genuine superoutburst, the short supercycle reported by Kato et al. (2001, IBVS 5120) may still continue. Regards, Makoto Uemura
