discov_num notes refcode
HJ 3608 gam Eri = 34 Eri = Zaurak. Variable?
The faint pair, presumeably the original system, was recovered in Dal2009
2009, which appears to have common proper motion. All subsequent
measures of the HJ 3608 were of a more distant pair with linear
motion relative to the primary, presumeably optical.
