LDN 1622, the Boogeyman nebula

Constellation: Orion

Lynds’ Dark Nebula (LDN) 1622, the Boogeyman nebula, is located in the constellation of Orion just east of Barnard’s loop, a portion of which can be seen to the southwest. It is thought to be only 500 Ly away from Earth. Link to interactive sky chart. The image below shows a close-up of VdB 62, the bright reflection nebula. The gases of the nebula envelop the star HD 288313, also known as V1793 Orionis or HBC 515, a very young orange dwarf of spectral class K2V, responsible for illuminating the cloud. V1793’s period of variability is approximately 2.26 days and it belongs to the class of eruptive variables, probably of the FU Orionis type. It is also a triple star, consisting of a close binary and amore distant companion. Link to interactive sky chart.
