We present a catalog of 1,143 periodic variables , compiled from our image-subtracted photometric analysis of the K2 Campaign-0 super stamp .
This super stamp is centered on the open clusters M35 and NGC 2158 .
Approximately 46 % of our periodic variables were previously unreported .
Of the catalog variables , we find that 331 are members of M35 and 56 are members of NGC 2158 ( { P _ { \mathrm { m } } ~ { } > ~ { } 0.5 } ) .
Our catalog contains two new transiting exoplanet candidates , both of which orbit field stars .
The smaller planet candidate has a radius of 0.35 ~ { } \pm~ { } 0.04 R _ { J } and orbits a K dwarf ( K _ { \mathrm { p } } = 15.4 mag ) with a transit depth of 2.9 millimag .
The larger planet candidate has a radius of 0.72 ~ { } \pm~ { } 0.02 R _ { J } and orbits a late G type star ( K _ { \mathrm { p } } ~ { } = 15.7 mag ) with a transit depth of 2.2 millimag .
The larger planet candidate may be an unresolved binary or a false alarm .
Our catalog includes 44 eclipsing binaries , including ten new detections .
Of the eclipsing binaries , one is an M35 member and five are NGC 2158 members .
Our catalog contains a total of 1,097 non-transiting variable stars , including a field \delta Cepheid exhibiting double mode pulsations , 561 rotational variables , and 251 pulsating variables ( primarily \gamma Doradus and \delta Scuti types ) .
The periods of our catalog sources range between 43 minutes to 24 days .
The known ages of our reported cluster variables will facilitate investigations of a variety of stellar evolutionary processes .
