Narrative:

After reaching 10000 ft and starting to accelerate, we get frequency change to center, almost simultaneously we got a TCASII alert while center gives us 360 degree heading and clearance to climb to FL200. TCASII recommended a descent. After nosing over to discontinue climb. Traffic was spotted at 1 O'clock position and passed off our right side. We then rechked our climb clearance and proceeded uneventfully. Center never had traffic. Supplemental information from acn 289115: thought target was same direction and quick climb would clear traffic. Traffic, however, was opposite direction and TCASII called for descent. Stopped climb as first officer called visual on traffic -- traffic passed 200 ft away.

Title: NMAC.

Narrative: AFTER REACHING 10000 FT AND STARTING TO ACCELERATE, WE GET FREQ CHANGE TO CTR, ALMOST SIMULTANEOUSLY WE GOT A TCASII ALERT WHILE CTR GIVES US 360 DEG HDG AND CLRNC TO CLB TO FL200. TCASII RECOMMENDED A DSCNT. AFTER NOSING OVER TO DISCONTINUE CLB. TFC WAS SPOTTED AT 1 O'CLOCK POS AND PASSED OFF OUR R SIDE. WE THEN RECHKED OUR CLB CLRNC AND PROCEEDED UNEVENTFULLY. CTR NEVER HAD TFC. SUPPLEMENTAL INFO FROM ACN 289115: THOUGHT TARGET WAS SAME DIRECTION AND QUICK CLB WOULD CLR TFC. TFC, HOWEVER, WAS OPPOSITE DIRECTION AND TCASII CALLED FOR DSCNT. STOPPED CLB AS FO CALLED VISUAL ON TFC -- TFC PASSED 200 FT AWAY.
