New dwarf nova in CrB

Dear dwarf nova fans,

According to IBVS No. 4343 (S.V. Antipin), a dwarf nova was discovered in the xi CrB field.

    16h 00m 03s.7  +33o 11' 15" (J2000.0)
             UG   14.5-(17.5p

The object has two types of outbursts, short ones and long (>15d) ones, though the data suggest the shorter ones are not necessarily fainter. The duty cycle amounts to ~20%. Won't someone add this to his or her monitoring program?
