Finding chart: BRNO VI - 94
One of the comparison stars is probably variable
Identifications of the variable and the comparison stars:
IL Mon = TYC 4837.2525 (V=10.55 mag)
A = TYC 4837.3337 (V= 9.55 mag)
a = TYC 4837.2146 (V=10.63 mag)
b = TYC 4837.0908 (V=10.07 mag)
c = this star was not included into Hipparcos and Tycho catalogues
d = this star was not included into Hipparcos and Tycho catalogues
e = this star was not included into Hipparcos and Tycho catalogues
f = this star was not included into Hipparcos and Tycho catalogues
