EIS 1 V382 Ser = GJ 3917. Eisenbeiss et al. (2007) use archival data from Eis2007
POSS-I (1950) and UK Schmidt red and IR (1981, 1992), plus 2MASS, as
well as followup H-band observation with the Omega-Cass IR camera at
the 3.5m Calar Alto telescope; derive pm of secondary similar to that
of primary. The orbital period is estimated at 7000y. Low-resolution
optical spectroscopy yields spectral type M2.5-3.5V for the secondary;
the derived distance is 24.4 +/- 4.2 pc.
