ERUPTIVE OBJECT IN AQUILA
Koichi Nishiyama and Fujio Kabashima, Japan, report on CBET 2075 their 
discovery of an eruptive object in Aquila at magnitude 10.9 on two 40-s 
unfiltered CCD frames (limiting magnitude 13.3) taken on 2009 Dec. 
14.39UT using a 105-mm f/4 camera lens.

Several confirming unfiltered CCD frames (limiting magnitude 18.4) taken 
around 2009 Dec. 14.41UT using a 0.40-m f/9.8 reflector yield mag 10.9 
and the following position for the object:

RA 19h 14m 09.73s DEC +15 16' 34.7" (2000).

Nothing is visible on their images of Dec 6.42UT (limiting mag 13.7) and 
7.42UT (limiting mag 13.6).  Following an appeal by the Central Bureau, 
P. Corelli, Italy using a 0.45-m f/4.4 reflector recorded the object on 
unfiltered CCD exposures of Dec 14.79UT yielding mag 10.8 and position 
end figures 09.69s 34.0"; Corelli adds that nothing is visible at this 
position on a Digitised Sky Survey plate (limiting red mag approximately 
21.5).

W. Vollmann, Vienna, Austria made a visual estimate on Dec 14.710UT at 
11.4.
