Help me identify this website log entry

[turtle]

I saw this in one of my site logs, what is something doing checking my wp-cron.php? Should I be concerned?

Host: 66.7.2XX.XX

/wp-cron.php?check=d057c86e0177c5e9ebbdd1834ed31188
Http Code: 200 Date: May 16 20:20:50 Http Version: HTTP/1.0 Size in Bytes: 0
Referer: -
Agent: -

The IP address is my shared host server.

I wouldn't worry about it, probably just the server checking for cron jobs.

Cool, thanks. :) I hate not knowing what's going on. :\
