IC 4636 is a star near Bigourdan's single estimated position. The identity is almost certain as he notes "It is followed by a * 12 which is on the same parallel and which follows 5 seconds later." The * 12 is closer to 7 seconds following, but it is close to where Bigourdan places it.

Some have taken IC 4636 to be identical with NGC 6279. Bigourdan, however, used the galaxy as the reference object for IC 4636, placing his "nova" +2.5 seconds, -2 arcmin 30 arcsec from the galaxy. In addition, the first part of his description reads, "At this position, I suspect an object similar to NGC 6279, but much fainter and considerably more stellar." All of this makes it certain that the two objects are not identical.
