LEP 59 AE: M4, spectroscopic distance 24pc. 75" from G5 dwarf HD 111398 =
HIP 62536 = 2MASS J12485242+1205469. Hipparcos pm for the G dwarf is
+235-140, consistent with the USNO-B1 pm for M dwarf of +234-119. Red2007a
E: 2MASS J12485345+1204326 is a wide (76") common proper motion
companion to HIP 62536 (Lepine & Bongiorno 2007), but is single in the Lep2007
AstraLux images. Jnn2012
