Note concerning Supernova 1999by in NGC 2841: I was not able to see
this object on May 3-4 00h07m UT in my 8-inch SCT, but due to a
better sky I managed to observe it near threshold on May 4-5
22h56m UT. The following comparison stars were used: F=13.51,
G=13.77, a=14.19. Identification of comparison stars are due to
G. M. Hurst (ref. TA E-Circular 1405), their V magnitudes are
measurements by H. Corwin and M. Frueh, and published by B. Skiff
[vsnet-alert 2937]. Form Norway, this object has also been
observed by O. Midtskogen (visually) and O. Trondal (with CCD).
Observer:
GRL = Bjorn H. Granslo (Fjellhamar, Norway). Instruments: 203-mm SCT
(C203), 70-mm refractor (L70), 10x50 binoculars (B10x50). Sequences
are AAVSO unless noted. Observations before 22h30m UT were made
from Blindern, Oslo.
