Hi to all,
I have a question about the behavior of a transistor.

A voltage source with 50Ω impedance generates voltage. Waveform of Vin is shown above(it varies between -2 and 4 Volts), and the total circuit is shown below.
Positive level of Vin is being changed, while negative level is being kept same. As a result, figures below show the voltage waveforms of Vc and V1.

Orange line shows the Vc(5V/div), Purple line shows V1(2V/div). Can you explain the behavior of the transistor in this circuit?
