All of them. Somebody, somewhere is always scanning your outside interface trying every port.
If you want to be flooded with information, just start logging everything that gets denied by turning on ip audit.
 ip audit attack action alarm  <== send syslog message
 ip audit info action alarm
 ip audit interface outside

sho ip audit interface outside

logging on
logging host

Use these commands and give the ip address in the second command to enable logging onto a syslog client. Get Kiwi Syslog (free) if you don't have one.
