Occasional clouds Brightness: 3-4 Alt: 60° Description: A cluster of faint (12m and fainter) stars around a reddish mag. 7 central star. Diameter about 8'. Quite sharp edges, but a trail of faint stars runs towards N from the N side. A very bright group of stars in situated slightly outside the field towards N.
