Unfortunately for me, I managed a trustee operation for 4 years here in AZ.
You can drive by the property and there should be a "Notice of Trustee's Sale" posted on the home. That notice will provide you with the date and time of the sale, as well as the name and number of the Trustee selling the home.
Just know that there are times when the current owner will do something to postpone the sale, i.e., file bankruptcy, file an injunction, lawsuit, etc.
Hope this helps. I'm available if you have any more questions or concerns.
