What might you see from the center line? Astronomers estimate that Sirius spans 0.006" and the asteroid 0.005". If accurate, this means Sirius will dim significantly but not disappear. But slight errors in those measurements could result in Sirius vanishing. In either case, it’s an event you won’t want to miss.
