731:, luminosity, and spectrum all classify it as an LBV. It shows brightness variations of a few tenths of a magnitude, but these do not seem to be associated with colour changes that would be expected from an LBV. The spectral type has varied slightly since its discovery, but not to the extent that would be normal for an LBV. If the lower Gaia DR2 distance were correct then the properties of Cygnus OB2 #12 would mean it would be expected to pulsate at low amplitude with a period of a few days.

640:, which was inconsistent with the distance of other Cygnus OB2 members. However, the result included a significant amount of noise suggesting that it may have been inaccurate. Earlier measures of the parallax were too imprecise to be meaningful. If the closer distance were accepted then the star would be a more conventional blue supergiant with a luminosity around 440,000

586:) away in Cygnus, and resides in a region of the Milky Way from which visible light is heavily absorbed by interstellar dust when viewed from Earth. The dust causes the star to be strongly reddened despite being an intrinsically hot and blue star, hence it has been extensively studied in the infra-red. Were it not for the dust
536:. This makes the star nearly two million times more luminous than the Sun, although estimates were even higher when the star was first discovered. It is now known to be a binary, with the companion approximately a tenth as bright. A very approximate initial estimate of the orbit gives the total system mass as 120
