Curt Roslund was a Swedish astronomer who discovered seven new open clusters spectroscopically. These clusters are not well defined and are not obvious objects. One of them - Roslund 4 - is located in Vulpecula constellation and is surrounded with two reflection nebulae: IC4954 and 4955. This complex is placed about 6500 light years away, and the cluster age is estimated to 4 million years. Scientists claim that it is a star formation region, though the amount of stars being born there is low.
