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

Historical observations

Dunlop, James (1828)

Dunlop, J. (1828) A Catalogue of Nebulae and Clusters of Stars in the Southern Hemisphere, Observed at Paramatta in New South Wales. Phil. Trans. Roy. Soc., 118, 113-151. [1828RSPT..118..113D]

James Dunlop observed from Paramatta, New South Wales, using a 9-inch f/12 telescope. His No. 438 is described as "a very faint nebula, about 1' diameter, round figure."

John Herschel

This galaxy has been cross-referenced with Dunlop 438, and was observed by John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "F, vL, R, vglbM, 3'; sky dull, a haze forming." On a second occassion he wrote: "faint; large; round; very gradually a little brighter in the middle; 2.5' across. With 9 inches aperture, and a mirror newly polished yesterday, and in high beauty, it is barely possible to discern with the utmost attention that this nebula exists; but to have discovered it with that aperture and power 180 would have been quite out of the question; possibly, however, 90 might show it better."
