Observers:
DAH = Haakon Dahle (Honolulu, HI, USA). Instrument: 25.6-cm f/4.95
  reflector (M254). Observations are Pogson step estimates and all
  were of class 2. Windy conditions on May 2. Dahle's observation of
  SN 1998bn was based on comparison stars not included in A. Henden's
  sequence for NGC 4462 (a = GSC 6682-0729, b = GSC 6682-0861). The
  GSC magnitudes in this area are generally in error by 0.5-1 mag.
GRL = Bjorn H. Granslo (Fjellhamar, Norway). Instrument: 20.3-cm SCT
  (C203), 10x50 binoculars (B10x50). Nearly clear, Moon, nautical
