We present results of an infrared study of the molecular cloud Lynds 1340,forming three groups of low and intermediate-mass stars. Our goals are toidentify and characterise the young stellar population of the cloud, study therelationships between the properties of the cloud and the emergent stellargroups, and integrate L1340 into the picture of the star-forming activity ofour Galactic environment. We selected candidate young stellar objects from theSpitzer and WISE data bases using various published color criteria, andclassified them based on the slope of the spectral energy distribution. Weidentified 170 Class II, 27 Flat SED, and Class 0/I sources. High angularresolution near-infrared observations of the RNO 7 cluster, embedded in L1340,revealed eight new young stars of near-infrared excess. The surface densitydistribution of young stellar objects shows three groups, associated with thethree major molecular clumps of L1340, each consisting of less than 100members, including both pre-main sequence stars and embedded protostars. NewHerbig--Haro objects were identified in the Spitzer images. Our resultsdemonstrate that L1340 is a prolific star-forming region of our Galacticenvironment in which several specific properties of the intermediate-mass modeof star formation can be studied in detail.
