32 Cygni (Omicron-2 Cygni)

This is an eclipsing binary of the Algol type. A red giant or supergiant is orbited by a blue star. But the dimming amounts to only 0.06 magnitudes, because the blue star can shine through the thin atmosphere of the red from behind.
At the giant protuberances (eruptions) with a length of 30 solar diameters have been observed.
