A weaker variable star, which shines only as a 16.2 magnitude star at its minimum, so it can only be seen in a large telescope. However, every three to four months, it suddenly brightens and within a few hours its brightness increases to 11.5 magnitude. For several days, it can then be seen even in a 150 mm telescope.
