| Evolution comments = BIG PCF system. Kinked NL straightens over a two and a half months. At least one eruption, June 6, when it is mostly still behind the limb. Appears larger (wider, higher) and darker at the limb before erupting in CME on July 23. Unfortunately, MLSO stops observing before this CME. |

| CME/dimmings association =
CME July 23; prominence eruption on July 23; | |
| Active region association =
N/A | |
| Filament/FC association = PCF-N; channel extending across disk, nearly parallel the whole way | |
