Sažetak:
The known FUOri- type young eruptive stars are exceedingly rare(a dozen or so confirmed objects)and 2MASSJ06593158-0405277, with its 2014 outburst, is likely the latest addition to the family. All members have displayed just one such eruption in the rrecorded history, an event lasting for decades. To test the FUOri nature of 2MASSJ06593158-0405277, we have reconstructed its photometric history by measuring its brightness on Harvard photographic plates spanning the time interva 1899–1989. No previous large amplitude eruption similar to that intiated in 2014 has been found, as in bona fide FUOri-type objects. The median value of the brightness inquiescence of 2MASSJ06593158-0405277 is B=15.5, with the time interva l935–1950 characterized by a large variability (∼1 mag amplitude)that contrasts with the remarkable photometric stability displayed at later epochs.The variability during 1935–1950 can either be ascribed to some TTau like activity of 2MASSJ06593158-0405277 itself or to the also young and fainter star 2MASSJ06593168-0405224 that lies 5 arc sec to the North and forms an unresolved pair at the astrometric scale of Harvard photographic plates.
