Abstract
Sympathetic phenomena on the Sun are events that occur at short time intervals in active regions located at large distances from each other. The presence of such events indicates that even very distant active regions may be connected physically to each other. In this paper, we present the results of analysis of several sympathetic bursts identified using the archive of observations on the Nobeyama Radioheliograph. Bursts in active regions spaced by 400 000 to 1 200 000 km occurred with a delay of 2 to 20 minutes. The estimated propagation speed of the disturbing agent is 1000–5000 km/sec.
