Observing Notes

Harold Corwin

The IC position, from Joseph Lunt working with the Cape Town 18-inch telescope, is much closer to NGC 7213 than to the galaxy we usually take as IC 5170. The difference in positions is only +0.5 minutes of time, and -1 arcminute from the NGC galaxy, but is -2.7 minutes and +2.3 arcminutes off the standard identification.

Lunt also gives no description for the object, so had he not mentioned that his new object was near NGC 7213, I suspect that we would have taken his object to be identical to John Herschel's. As is, with no other galaxy within nearly a degree being as bright, I can see why the southern observers took this object for IC 5170. Given the history, I'll do the same, though with the caveat of the large position difference.

See IC 5224 for a bit more about Lunt's short list of new objects.
