Stellar population and the interstellar gas-dust medium in the vicinity ofthe open star cluster vdB 130 are analysed using optical observations takenwith the 6-m telescope of the SAO RAS and the 125-cm telescope of the SAI MSUalong with the data of Spitzer and Herschel. Based on proper motions and BV andJHKs 2MASS photometric data, we select additional 36 stars as probable clustermembers. Some stars in vdB 130 are classified as B stars. Our estimates ofminimum colour excess, apparent distance modulus and the distance areconsistent with young age (from 5 to 10 Myrs) of the cluster vdB 130. Wesuppose the large deviations from the conventional extinction law in thecluster direction, with $R_V$ ~ 4 - 5. The cluster vdB 130 appears to bephysically related to the supershell around Cyg OB1, a cometary CO cloud,ionized gas, and regions of infrared emission. There are a few regions ofbright mid-infrared emission in the vicinity of vdB 130. The largest of them isalso visible on H-alpha and [SII] emission maps. We suggest that the infraredblobs that coincide in projection with the head of the molecular cloud are HIIregions, excited by the cluster B-stars. Some signatures of a shock front areidentified between these IR-bright regions.
