Subject: SN81B data

Dear Dr. Jeffery,
  I send you part of our SN light curve catalog with data for
SN 1981B. The columns are: SN Id., JD, U, B, V, R, I magnitudes,
code for reference, * means photoelectric observations, all
other are photographic. References are given below.
(My paper is ref. 01). You may find these and other data on SNe
at http://www.sai.msu.su/groups/sn , although it is still under
construction.
With best wishes,
Dmitriy Tsvetkov
