It is located at: RA 23h 38m 48.41s DEC -6 31' 21.3" (2000) which is 4"W and 17"S of the core of NGC 7721. At the request of the Central Bureau, H. Yamaoka, Japan reports that K. Itagaki, Japan has confirmed 2007le at mag 14.9 on an unfiltered CCD image taken with a 0.60-m reflector on Oct. 14.565; nothing is visible at the position of 2007le (to limiting mag 16.0) on an image taken by Itagaki on Oct. 10.666. Guy Hurst, Basingstoke, England, reports that photometry of an unfiltered image 2007 Nov 1.016UT with the Bradford Robotic Telescope gave a magnitude of 13.9 suggesting the object was then still on the rise to maximum.
