J-K=1.48. Period changes. The NSVS data (1999-2000) fits ASAS-3 data with a period of 276 d. (Epoch 2451335). Period in ASAS-3 data (2005-2008) alone is 273 d. (Epoch 2454653). Recent Dauban data (2012) shows a period of 271 d. (Epoch 2456272) when combined with ASAS-3. Dauban CR and NSVS R1 magnitudes have been shifted to match the ASAS-3 V scale. NSVS magnitudes were corrected for light contamination from nearby stars. Minimum magnitude from GSC2.3.
