NSV04114: detection of large-amplitude variation by Toa
Akira Takao (Kita-kyushu, Japan) reports the discovery of large-amplitude
variation in NSV04114. From the amplitude in unfiltered CCD photometry,
the object is most likely a Mira-type variable. The object was also
recorded at maximum (11.6p) in 1999 October by Katsumi Haseda.
