1 Furgoni, Riccardo Min II = 12.06 V with eclipse duration = 6%:. The great difference between eclipse duration in Min I and Min II is indicative of a very eccentric system. Min II observations are better phased with slightly shorter period suggesting possible apsidal motion. Elements for Min II are HJD 2451486.75 + 18.3007 x E. Spectral type taken from Skiff, 2014. Ensemble comparison stars taken from APASS (UCAC4 761-021906 12.498 V; UCAC4 761-021905 12.566 V).
