SMC Network Router Logs - TCP FIN scans?

Hi - Just wanted to ask if I could get some insight on these logs from my router. I noticed a lot of TCP FIN scans and after that send requests/recieve ACK message. When I search the whois for the request IP, it appears to be my ISP's address in Calgary. Can anyone shed light on this for me? Is this something to be worried about? Thank-you.
