This occurs very quickly and the two transistors swap states. The flashing frequency depends on the value of C1, C2, R2 and R3. There will be a slight difference between the gain (the ability to amplify) of the two transistors, Q1 and Q2 and one of them will turn on faster to start the circuit flashing.
