Godaddy holds the auction while the domain name is in redemption period. You should be able to figure out when the domain will drop by looking at the expiration date and following it through the cycles up until pending delete. Its probably something like 5-10 days until it goes into pending delete after the closeout ends
mmm nope. They don't auction domains in Redemption. They do it before they go in Redemption as it is too expensive to get our of it.
Auction or not, if the domain is not renewed, it goes through the same process with the same timeframes
