1 Furgoni, Riccardo Aperture photometry was performed on the blended source formed by the variable and the close companion 2MASS J19194382+2758185 that lies 4.4" away. Subsequently, the magnitude of the companion (13.45 V) was measured from a stack of 30 frames (in order to improve the SNR and highlight the small separation) and subtracted from the blended source. Ensemble comparison stars magnitude derived from CMC14 r' mag (UCAC4 590-080783 = 11.119 V; UCAC4 590-080567 = 11.781 V).
