(Reuters) - Powerful solar flare activity is forecast for Monday which may interfere with short-wave communications, Russian scientists said after three flares were observed on the sun on Sunday.

The Fedorov Institute of Applied Geophysics in Moscow said class X flares were possible, including proton flares, and short-wave radio conditions were expected to deteriorate.
