W Notes: AB 1879: 81.4 @ 325. 6 measurements. AC 1874: 140.4 @ 322. 11 measurements. The primary of this optical pair is variable. From James Kaler's Star Notes: Enif is a coolish, orange class K supergiant with a temperature of 4,460 Kelvin. Its diameter, which from direct measurements of angular diameter and its luminosity and temperature is 150 times that of the Sun, is large enough to take the star halfway to the orbit of the planet Venus. If Enif were our star, it would appear 40o across in our sky, about the angular extent of the entire constellation of Pegasus itself. As a supergiant, Enif is both dying and massive. It seems to have a mass around 10 times that of the Sun and is now either fusing its helium into carbon and oxygen or is about to start. Like Betelgeuse, it might either explode as a supernova or turn into a heavy, rare neon-oxygen white dwarf that has shrunk to less than the size of Earth. Even with all these great qualities, however, Enif still seems like an ordinary (if such there be) supergiant. Two characteristics set it apart. It seems to be part of a family of three very similar supergiants, the other two the Alpha and Beta stars of nearby Aquarius, Sadalmelik and Sadalsuud. The triplets, all at roughly the same luminosity and distance (Sadalmelik at 760 light years, Sadalsuud at 610) may have been born together in the same extended group, and over the past 15 or so million years of their existence have drifted well over 100 light years apart. Most intriguing, however, is Enif's possible erratic and violent behavior. In 1972, an observer in Florida saw Enif as bright as Altair in Aquila, five times brighter than normal, whereupon it faded. For over 10 minutes it appeared to pop some kind of enormous flare, one vastly brighter than the small ones that occur frequently on the Sun. Such events are rare— only two dozen or so are known— and not well documented, nor is there any theory for them.
