 Curved dark marking, 1 long. This curved marking, convex to the north, is much broken with darker masses. The position given is for its center. The star BD+592291 (8.0 mag) is close to its northeast edge. Its east end is in about a = 20h 51m 00s, d = +59 45'. The west end curves southward and ends near BD+592283 (8.2 mag) (see ibid., 43, 1-8, 1916, Plate I, and Proceedings of the National Academy of Sciences, 1, 394-96, 1915).
