ABSTRACT
A series of photoelectric measurements of the planetary nebula NGC 6210 were carried out in May, 1999 using a 0.51m Newtonian telescope along with an SSP-3 solid state photometer and filters that have been transformed to the Johnson B, V, R and I system. The respective B, V, R and I magnitudes for NGC 6210 are: 9.70[+ or -]0.02, 9.08[+ or -]0.02, 9.66[+ or -]0.02 and 10.35[+ or -]0.04. If a distance of 1.57 kiloparsecs is used for NGC 6210 then the absolute magnitudes of this object are: -1.28, -1.90, -1.32 and -0.63 for the B, V, R and I filters respectively.
