The V380 Ori Group: The Blue Image
This is the blue image.
You may also see images at other wavelengths by clicking on the
colorbar at a point above any of the dashed arrows (which point to other
regions of the spectrum at which images are available). The solid arrow
shows the spectral region you are seeing now.
This is not intended to be a linear scale in wavelength, but only a rough guide to
the wavelength of the observation.
The V380 Ori Group
This group of stars is a small star forming aggregate lying just south
of the L1641N group. V380 Ori, the optically brightest object in this
group has been recognized for a long time as a member of the Herbig
Ae/Be star population (Herbig 1960), a young intermediate mass star.
This star is the bright
object illuminating the large reflection nebula (NGC 1999). The
original H-H objects (Herbig 1951, Haro 1952) are also found in this field.
They are the nebulous objects in the lower half of this image.
An optical infrared study of this region (Strom et al. 1985) was able to
identify the powering source of the outflow, of which HH 1 & 2 are the
visible manifestations, as the cm wavelength VLA source discovered by
Pravdo et al. (1985). A water maser source, detected by both the VLA and
IRAS also lies within this field as do numerous other extremely young
objects as shown by the luminosity function derived for the region by
Strom, Strom and Merrill in their infrared imaging study of
This image was made with an optical CCD with a broad band filter centered
at a wavelength near 4300 Å. While the images are not exactly aligned, you
can easily see that not much remains visible at this wavelength.
