Frequently when notating the super locrian in regular notation the 3rd may be notated enharmonically as the dim 4th. This makes it easier for sightreading if the b9 has been notated as Ab, and the #9 as Bb. When the eye scans the sequence of notes during sightreading, it is often easier to see the Cb. This is relative and again may vary depending on the overall context. The bottom line is that different sources label the super locrian differently. It is not uncommon to see a G super locrian notated in G as G-Ab-Bb-Cb-Db-Eb-F. Because there are 7 different root notes, this is visually more “scalar” than G-Ab-A#-B-C#-D#-F where the E or one of the other notes is omitted to make room for the 2 9ths (Ab & A#). Hope this clears up any confusion this may create…
