PROPOSAL: To explore the variability of NSV 14244. 3 hour time series in each of B, V, R, and I bands with an ~10 minute cadence are requested nightly using multiple AAVSOnet telescopes over one month as weather and telescope time permits.

RATIONALE: NSV 14244 was imaged incidentally in a time series of another variable star. Magnitudes are noted in the table below:
JD+2456955 0.65553 0.66128 0.66681 0.67250 0.67819
Mag 10.520 10.542 10.542 10.535 10.519
SNR 137 136 136 135 136

Standard deviation was 0.011. This data set is minimal, but appears to be non-random. The pattern suggests the possibility that this is a rotating variable, perhaps an ELL. VSX lists only 3 observations of this target with no classification and provides no references. A rich set of observations of this target would allow much more precise data analysis including a phase plot which could result in its classification.
