Narrative:
I was working RA; aircraft #1 checks on; is descended to FL230. Aircraft #2 checks on and is descended to FL220. Aircraft #2 reports moderate turbulence. I went to get a PIREP form; filled it out and turned it in to my supervisor. When I sat back down; the radar controller asked for an altitude report from aircraft #2. I missed the 1-2 mins leading up to the proximity event.

Title: ZBW RADAR ASSOC CTLR DESCRIBED LOSS OF SEPARATION EVENT; ALLEGING OTHER DUTIES PREVENTED CONTINUOUS POS MONITORING.
Narrative: I WAS WORKING RA; ACFT #1 CHKS ON; IS DSNDED TO FL230. ACFT #2 CHKS ON AND IS DSNDED TO FL220. ACFT #2 RPTS MODERATE TURB. I WENT TO GET A PIREP FORM; FILLED IT OUT AND TURNED IT IN TO MY SUPVR. WHEN I SAT BACK DOWN; THE RADAR CTLR ASKED FOR AN ALT RPT FROM ACFT #2. I MISSED THE 1-2 MINS LEADING UP TO THE PROX EVENT.
