  We report on the discovery of three candidate eruptive young stars, found
during our comprehensive multi-wavelength study of the young stellar population
of the dark cloud L1340. These stars are as follows. (1) IRAS 02224+7227 (2MASS
02270555+7241167, HH 487 S) exhibited FUor-like spectrum in our low-resolution
optical spectra. The available photometric data restrict its luminosity to 23
L_sun < L_bol < 59 L_sun. (2) 2MASS 02263797+7304575, identified as a classical
T Tauri star during our H alpha survey, exhibited an EXor type brightening in
2005 November, at the time of the SDSS observations of the region. (3) 2MASS
02325605+7246055, a low-mass embedded young star, associated with a fan-shaped
infrared nebula, underwent an outburst between the DSS1 and DSS2 surveys,
leading to the appearance of a faint optical nebula. Our [SII] and H alpha
images, as well as the Spitzer IRAC 4.5 micron images revealed Herbig-Haro
objects associated with this star. Our results suggest that amplitudes and time
scales of outbursts do not necessarily correlate with the evolutionary stage of
the stars.
