  This study shows that the carbon star CGCS 673 is a semi-regular (SR)
variable star with a period of 135 d and an amplitude of 0.18 magnitudes in the
V-band. The light curve obtained by this study correlates well with the SR
classification as the photometric data obtained shows noticeable periodicity in
the light changes of CGCS 673 that is occasionally interrupted by a period of
irregular variability. The derived period and colour index obtained from our
data and those from professional databases indicate that the at-tributes of
this star fall within the parameters of the Semi-Regular class of variable
stars. Following our notification of the discovery that this star is a variable
source, CGCS 673 has received the AAVSO Unique Identifier as (AAVSO UID)
000-BMZ-492.
