Abstract
The rotational modulation and variability of the mean brightness of th ree poorly studied spotted red dwarfs are considered. Their photometri c behavior can be described well by a zonal spottedness model. The are as of the spots comprise up to 11-13% of the total stellar surface, an d the spots themselves are 600-1500 K cooler than the surrounding phot osphere.
