SUPERNOVA 1994ag IN ANONYMOUS GALAXY
     N. B. Suntzeff reports that his observations (details as given
on IAUC 6115) on Dec. 12.2 UT show that the object reported on IAUC
6113 has features consistent with Na D and red TiO bands, suggesting
that the object designated SN 1994ag is probably an early M dwarf.
