I'm not sure we hit it, yet.
The only way to know when the bottom is is to pass it, see the continuous upward trend in sunspot numbers, SFI, etc. and then go back and define where the bottom "was."
Based on that, I'm not sure we've even hit the bottom yet; however it's very likely to occur within the next few months (if it didn't already).
Some experts are predicting a ho-hum Cycle 24 that won't even be as good as Cycle 23; other experts are predicting a hum-dinger that may even surpass Cycle 19. I favor the latter, out of hope and not science!
