Stellar Notes
EA 6.37 - 6.61V, 2.49955d = SB period. Secondary eclipse amp. 0.06V; primary not yet observed.
AB 7.1 A5m, 7.2 late F, 53.0y, a = 0.321". C, 10.5v at 18" binary around AB.
ADS comp. A, 5.9766d, K 42.5k/s, V0 -11.8k/s, asini 3.49; comp. B, 2.49955d, K 86.1k/s, V0 -4.6, asini 3.96. | HR 3337 is an SB2, but each of the two components appears to be an SB1 with a different period.
H/K/met give A6/F1V/F2.
