Observing Notes

Harold Corwin

IC 1028 = NGC 5739. Here is my previous note:
Assuming that the identification (first suggested by CGCG) is correct, [this] is well off its nominal position: +45 seconds in RA and +10.7 arcminutes in declination. There is a "F * close nf", but I would hardly describe the galaxy as "pB, S, R". "Small" it is, but it is faint and elongated. I've saved the identity since the galaxy is the only one in the area that comes even close to fitting both Swift's position and description.

For more about Swift's unfortunate night -- one among many -- of 1 September 1888, see IC 895.
In August 2017, Steve Gottlieb wrote that Swift's RA for IC 895 (which see) is probably ten minutes of time too small. This error would make that object identical with NGC 5273.

Following Steve's suggestion, I applied the same 10-minute error to Swift's position for IC 1028 and found it to be identical to NGC 5739. Swift's description -- including the "F *" -- fits perfectly, and given the simple digit error, I've no doubt that this is the correct object.
