Korean astronomers detected a new object at mag 10.8 in Pegasus, near its borders with Cygnus and Vulpecula. The initial observation was on May 6 at about 18h; by the same time on May 7 it had brightened to mag 8.4. The location of the object is: RA 21h 38m 06s.571, Decl. +26º 19' 57".33

The object is now being classified as a dwarf nova of the WZ Sagittae type - that is, a binary star in which material from one star falls onto a white dwarf and eventually causes an outburst. This particular binary star appears to have a period of about 82 minutes. Dwarf-nova outbursts can take place every few decades, so this star will probably have another outburst in years to come.
