The general-relativistic effects of an extreme Reissner-Nordström
black hole on the flux of radiation emitted by a hot spot orbiting the
hole with a thin accretion disk are investigated. The light curves, the
redshift factor, and the solid angle against the spot orbit position are
given. The results are then compared with those of a spot orbiting a
Schwarzschild black hole.
