                       V 1057 CYGNI

This star has been observed since August 1971; visual 
estimates with my 15-inch reflector. Observations have been
made as follows (comparison star, close beside the variable,
being taken as 10.9):


1971:   41 observations;   mean mag.   10.7
1972:   46                             10.8
1973:   14                             11.1
1974:   21                             11.2
1975:   38                             11.3
1976:   32                             11.4
1977:   17                             11.5


   Though the observations are less numerous than is 
desirable (mainly due to my illness), there seems to be a slow 
decline. On 1978 January 17 I made the magnitude 11.6. On my
next observation, on May 24 1978, the magnitude was found to have
fallen to 12.0: a dramatic decline. It was 12.0 on May 25, 11.9
on May 29 and 11.8 on June 2.
   If the magnitude of my main comparison star is adjusted
from 10.9, these estimates will also need adjusting, but the 
decline appears to be definite.
