  We present two new planetary systems found around cool dwarf stars with data
from the K2 mission. The first system was found in K2-239 (EPIC 248545986),
char- acterized in this work as M3.0V and observed in the 14th campaign of K2.
It consists of three Earth-size transiting planets with radii of 1.1, 1.0 and
1.1 R Earth, showing a compact configuration with orbital periods of 5.24, 7.78
and 10.1 days, close to 2:3:4 resonance. The second was found in K2-240 (EPIC
249801827), characterized in this work as M0.5V and observed in the 15th
campaign. It consists of two transiting super-Earths with radii 2.0 and 1.8 R
Earth and orbital periods of 6.03 and 20.5 days. The equilibrium temperatures
of the atmospheres of these planets are estimated to be in the range of 380-600
K and the amplitudes of signals in transmission spectroscopy are estimated at
~10 ppm.
