So, what are alternate minimums when flying IFR? Standard alternate minimums require the forecasted conditions at the time of arrival be at least 2 miles visibility and at or above 600 foot ceilings for precision approaches, or 800 foot ceilings for non-precision approaches.

The standard minimum weather requirement for an alternate is 600-2 if there’s a precision approach available and an 800-2 for a non-precision approach. (Note that the visibility requirement is the same.
For your alternate airport to meet the requirements of FAR 91.169, the weather conditions at the ETA must meet or exceed: If a usable precision approach is available: 600’ ceilings AND 2 SM of visibility.
