That corresponds to ~0.13% change in angle in apparent diameter. So at best, a totality will change to/from just a few tiny Bailey beads. Yet it could mean a 50-fold change in brightness! | |

Jan 7, 2023 at 16:50 | comment | added | Greg Miller | I think one case to consider is an observer viewing an eclipse at sunrise/sunset. At the equator, that person would be moving about 1000Mph towards or away from the moon. I think it's conceivable an observer could move from a distance of annularity to totality. I doubt there's an eclipse where this actually happens though. | |
