After R.Prager (Geschichte und Literatur des Lichtwechsels der 
Veraenderlichen Sterne, Zweite Ausgabe, Erster Band, Berlin, 1934) we 
know that CI AQL was first classified as Nova by Parenago (P.Z. 33,34). 
He analyzed 19 plates taken at the Simeis Observatory: only on two of 
them (on 1909/08/10 and on 1926/07/05) he found CI AQL (both at 
mag.15:); Parenago deducted that it is a Nova as on the plate taken by 
Reinmuth at the Koenigstuhl Observatory (AN 5399) on 1917/06/25 the star 
was recorded at mag.11.

References listed in H.Schneller (G.u.L., 1936) are:

J.d.2427604 don't show stars brighter than mag.12-13 in the position of 
CI AQL."
