New cataclysmic variable in Camelopardalis DDE 22 (USNO-B1.0
1597-0071405, 2MASS 04304278+6944281, GALEX J043042.9+694428) appears

I request the confirmation of outburst, and should it be confirmed -
time-resolved photometry (if someone can do time series for an object
that faint). The maximum brighthness of star is perhaps 15.5-15.9.
Star has been added to AAVSO VSX as DDE 22 with AUID 000-BKD-609.
10'x9' color-combined DSS finder chart is available at
I was using 147 as comparison star and 166 as check star.
This would be the first observed outburst of this star since its
discovery a month ago. See arxiv:1108.5122 and
