| Abstract: | The open cluster NGC 5617 was investigated by the strip method on charts of photographs with different exposure times taken with the 1-m Schmidt telescope of the European Southern Observatory. The cluster contains about 460 stars with a total mass of 700 Msolar. Its radius amounts to 3.7 pc; the star density in the center is 50 stars pc-3; and the mean stellar velocity, 0.89 km s-1. On longer-exposed photographs at a distance of 12.3' in direction to SSE an unknown open star cluster becomes visible with a radius of 4.3', containing about 150 stars to the limiting magnitude V=19m. |
