We report the discovery of 4 new H 2 jets in Mon R1 star-forming region on the images obtained with the 2.5-m telescopeof the Caucasian Mountain Observatory of SAI MSU through the lter, centered on the H 2 1–0 S(1) emission line. Thisdiscovery conrms the nature of these ows, which existence was previously suspected using archival Spitzer GLIMPSE360and WISE survey images. Also two infrared reection nebulae were revealed. On the Herschel PACS survey images we founda small group of far-infrared sources, mostly new ones. Among them are the possible exciting objects of these outows.Spectral energy distributions of new sources show their extremely red colour and the bolometric luminosities reaching 3L ⊙and even 10L ⊙ . Several of them should belong to Class I and even to Class 0 objects.
