I noticed there were three different expirations at the same strike on SPY options. I'm guessing one of them is the quarterly one, but what is the last one?

.....three different expirations at the same strike on SPY options.

?.....quarterlies, monthly American-style expiration and monthly European-style expiration??

I just recently noticed the Weeklys on SPY, IWM, DIA. Going to make calendar trading much more fun and interesting.
