GCVS position 11 43 35.00 +71 42 09.0 (J2000.0). No star there.

Otero, Sebastian Alberto
The variable is lost. No 12.9-mag. star at this position. No eclipsing binary with this period has been found either.
The star is probably the same as DO Dra, a CV with range 10.0 - 16.5 V. The GCVS keeps both entries separated so care should be taken not to confuse one for the other.
