Green, ed.) that Koichi Nishiyama, Kurume, Fukuoka-ken, Japan, and Fujio Kabashima, Miyaki-cho, Saga-ken, Japan, report their discovery of a possible nova in Aquila [V1722 Aql] at magnitude 10.9 on two 40-second nfiltered CCD frames taken on Dec. 14.398 and 14.399 UT. Confirming unfiltered CCD frames taken around Dec. 14.408 show the object at magnitude 10.9.

Coordinates: 19:14:09.73 +15:16:34.7 (equinox 2000.0)

Nothing is visible at this position on their frames taken on Dec. 6.417 down to magnitude 13.7 and 7.412 down to 13.6. 

After being posted on the CBAT unconfirmed-objects webpage, P. Corelli, Pagnacco, Italy, reports that a 5-second unfiltered CCD exposure taken on Dec. 14.791 UT showed the object at position end figures 09.69s, 34.0" and magnitude 10.8. According to Corelli, Corelli nothing is visible at this position on a Digitized Sky Survey plate down to red mag approximately 21.5. W. Vollmann, Vienna, Austria, reports the object at visual magnitude 11.4 on Dec. 14.710 UT.
