Abstract

We present the results of long-slit spectroscopic observations of a collimated outflow associated with the infrared source IRAS 01166+6635. The observations were carried out with the 6-m telescope of the Special Astrophysical Observatory using the SCORPIO-2 focal reducer. The structure of the outflow was investigated in detail, and several previously unknown knots were identified. The total projected length of the outflow was found to be approximately 0.36 pc, while its kinematic age was estimated to be less than 2,000 years. In addition, the electron densities of several outflow knots were estimated, revealing a decrease in density with increasing distance from the source driving the outflow.
