Anomalies will only show once until you have seen most of the anomalies in the game (I saw my first repeats at 75, I would assume this is the threshold).

In Normal mode, each hour may have 1-6 anomalies.
In Nightmare mode, each hour may have 3-8 anomalies.

After finishing the game once, the main menu will have a grid showing the numbers 1-100, each anomaly is assigned to one of these numbers and it will show whether or not you have exorcised it yet. However, there is no way to actually view the anomalies here so there's no way to know which anomaly belongs to which number.
So this list will be in the order that I found the anomaly categorised by what room it is in, not in the same order as on that grid.
