another occultation variable star from the crust, with a magnitude change from 3.9mag to 4.2mag over a period of 2.66 years - 972.18 days, the second longest known period. The decline in brightness from maximum to minimum, or rise from minimum to maximum, lasts only a few days, the star remaining at minimum for 38 days. The main component is red, the minor component is blue. Sometimes bright blue stars come to us through the outer layers of the red supergiant, producing interesting spectroscopic phenomena.
