Warning: date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone. in /home/yivumoo/public_html/show_object.php on line 167

History and Accurate Positions for the NGC/IC Objects (Corwin 2004)

NGC 7202 is a star. JH has only one observation of it, though he swept the area three times. Interestingly, he never saw more than three objects in this field in any sweep, and picked up only two in one sweep. Nevertheless, he entered the group as four nebulae in GC, in spite of his descriptions clearly stating that there were only three nebulae in the area. Still, this is not a compact group, with N7201 and N7204 being separated by 13.5 arcmin, so he probably realized that he could have easily missed one.

He stresses in a note that the RA is determined relative to NGC 7203 -- he puts it exactly one second of time preceding. The declination difference also puts N7202 exactly 3.0 arcmin south, so I suspect that this, too, is a relative determination, perhaps a simple estimated distance.

In any case, the object at the offset is a star; it matches JH's description ("eF, S, star like") as well.

Historical observations

John Herschel (1847) Cape Observations

Discovered by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "eF, S, star like, the 2nd of a group of 3." The three objects are NGC 7201, NGC 7202 & NGC 7203.

Published comments

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a nonexistent object. Their coded description reads NF DC.
