[vsnet-obs 1297] historical outbursts of KX Aql

[tkato@kusastro.kyoto-u.ac.jp]

    During a survey of V419 Lyr history, I have noticed a (probably) little-
known literature concerning the popular(?) target KX Aql, which experienced
a short faint outburst in 1994 Dec.

    G. A. Garbusov (Perem. Zvezdy suppl. 3, 639, 1979) gave following
outbursts from 550 Moscow & Simeiz plates.

     JD         mag
  2436432-4  12.9-12.7
    37964      15.0
    38943      13.2   (negative in the table?)

    D. Hoffleit (HB No.887, 1932) gave two outburst dates: JD 2425152 and
2426272.  From these data, Garbusov concluded that the outburst cycle
of KX Aql should be ~1000 days.

    "Outburst Activity Data on Selected Cataclysmic Variables" by Vanmunster
and Howell lists several additional outbursts recorded recently.  Before
1994, no definite outbursts had been recorded since a bright one in 1980
despite close monitoring.  Am I correct?

    I hope this information would supplement our knowledge on this object.
