HD 15524 is a wide binary star[3] in the northern zodiac constellation of Aries. Located approximately 51.76 parsecs (168.8 ly) away,[8] the primary, a yellow-white subgiant[4] or main sequence[5] star has an apparent magnitude of 5.97, meaning that it can be viewed with the naked eye under good conditions. The secondary, separated from the primary by 12.4 arcseconds, has an apparent magnitude of 10.4.[3]

This system is the likely source of X-ray emission coming from these coordinates.[12]
