Narrative:
Pilot (IFR) stated he just had a near miss with an aircraft at his altitude in IFR conditions. This was the first time we noticed the VFR target. No altitude readout associated with it. VFR target came and went a few more times before remaining steady on radar. (Pilot undecided about filing a near miss report).
