Default Is this normal? (CEL related)

I got a P0139 O2 sensor circuit slow response (bank 1 sensor 2)
Now today...it just went away.
Am I in the clear now? or should I still get it checked out?

Also...this is the rear sensor right? The dealer said it was the front..but everything else I've read says it's the rear.

Thanks for any help.

well it may be what I had at one point

My CEL came on after I bought her, and then it would go away and come back. I went into the dealer to get the one recall fixed, and they checked it for me. Turns out it was a bad right rear O2 sensor. They replaced it, and havent had a CEL since.
