HD 160529 is a hypergiant star located in the constellation of Scorpius. With an apparent magnitude of around +6.8 cannot be seen with the naked eye except under very favorable places, but it's easy to see with binoculars or amateur telescopes.
It has a spectral type of A3 and lies at a distance that has been estimated to be 2.5 kiloparsecs (8,200 light years); however this distance is uncertain and values between 1.9 kiloparsecs and 3.5 kiloparsecs have been proposed.
Most noticeably, HD 160529 is also classified as a low-mass luminous blue variable as both its brightness and spectral type have been observed to change between 1983 and 1991, fading 0.5 magnitudes and changing from A8 to B9; however its luminosity has changed very little.
