Scientific paper

The flux densities of a uniform sample of extragalactic radio sources in a narrow strip of sky (1° wide in declination with a total area of about 0.1 sr) were monitored for 105 days at 1420 MHz using the 64-m Kalyazin radio telescope. In total, 32 bright sources with flux densities greater than 0.6 Jy have been studied. The statistical properties of the observed flux-density variations are discussed. We detected variability at the 95% confidence level according to the χ 2 test in 4C +27.15 (0516+2740). The flux density variations in this source show the pattern typical of extreme scattering events. There are reasons to classify this source as a blazar.
