| Role | Degrees in Leo | Nakshatra | Width |
|---|---|---|---|
| Sub-lord | 11°26′40″ – 13°20′00″ | Magha (Ketu) | 1.89° · ≈8 min of Ascendant motion |
| Sub-lord | 24°00′00″ – 25°53′20″ | Purva Phalguni (Venus) | 1.89° · ≈8 min of Ascendant motion |
Mercury rules no nakshatra inside Leo, so it can only act here as a sub-lord (or as the sign-level dispositor).
The narrowest Mercury sub-lord slice in Leo is 1.89° wide, about 8 minutes of Ascendant motion; the widest is 1.89° (≈8 min). The Ascendant moves roughly 1° per 4 minutes on average, so a few minutes of birth-time error can change the sub-lord.
