Abstract

Preliminary results from a pilot program to monitor the intranightoptical variability in Seyfert 2 galaxies are reported. This program is designed to test some of the prominent theoretical mechanismsproposed for the origin of optical microvariability in active galacticnuclei (AGN). Two out of 3 Seyfert 2 galaxies observed show evidence formicrovariations. This detection can provide important constraints forthe models utilizing discrete events on accretion disks.
