Position: RA 18:48  DEC 37:00
Description:
In Lyra, just SE of Zêta1 Lyr. Quite mysterious object, covers a very large
surface under Zêta1 Lyr, but it does not seem to have any star concentration at
this place. The number of stars is too high to count them, and it would be even
difficult to determine which star is, in fact, part of Isk 1 and which star it
is not. From the original discovery by Iskudarian and Saakian (1961), they
regarded it as a cluster of white dwarfs, but nobody seems to know the true
nature of the object.
