Narrative:

A rotary winged aircraft was observed ahead of us at approximately the same altitude. Our course was 283 degree on top of scattered clouds at 4500'. We started a climb and the other aircraft passed approximately 200' below us and slightly north of us. It was red/white/black. We did not get the full registration number.
