Additional Instructions: 
Need only "pulse-timing" runs - just long enough to accurately define the phase of their pulses. Usually that means 1-2 hours are enough - assuming that the star is reasonably bright, the period reasonably short, and the amplitude reasonably high. For stars failing on one or more of these criteria, a tad longer would be nice. We especially seek beginning-and-end-of-observing-season time series. These observations are harder to get, but they nail down the cycle count between seasons, which allows derivation of the long-term (over many years) period change - which in turn permits measuring the accretion torque on the underlying magnetic white dwarf.

PNV J19150199+0719471

Showing periodic waves. The first recorded outburst ever, and likely caught quite early.

Additional Instructions: 
Arto Oksanen reports that comp star 145 (000-BKZ-638) in the AAVSO sequence is variable. Tim Crawford has updated the sequence by removing the label for this comp. Be sure to use the most recent seqence. Observe it early, late, and often. Because of the brightness, consider using a V filter - not essential but somewhat helpful in data reduction (almost zero differential extinction) and in archiving. Enrique's comp star is the AAVSO 119 star (V=11.921), and check is the AAVSO 126 star (V=12.625). These stars will probably suffice until the dwarf nova gets quite faint.
