IC 579 may be MCG -02-26-005, but the MCG galaxy is 23 arcmin north of Swift's nominal position. The RA's are identical to within Swift's usual (rather large) error, which makes this the only reasonable candidate near Swift's position. However, it is fainter than I'd expect for an object that Swift describes as "pF, pS, R" (unfortunately, he has nothing about the star field).

I have not yet checked for digit errors in the position. Perhaps Swift's Dec is one degree or ten degrees off. Or maybe his RA is ... (and so on). This should be checked before pronouncing the MCG galaxy as certainly being the object Swift dug out.
