What is this?

    AWI0002odb

    What is it?

    enter image description here

    I don't mean that object in the center of the image. I mean that object at the 11 o'clock position on the edge of the red circle. About this object aren't available any informations at all. I tried VizieR, SIMBAD and NED, but without success.

    If you try VizieR, you only get informations about the nearest object (which is object in the center of AWI0002odb ).

    This "strange" object appears violet in the 2MASS images, but It's not visible in DSS and WISE images.

    It's coordinates are 21:36:25.27 +59:18:34.8 (RA,DE)

    It appears, that this object is visible only in 1.24 μm, 1.66 μm and 2.16 μm, which are 2MASS images, so I hope that this is more then just some artifact in 2MASS images .

    Well, I figured out. I found more of them, and then I realize that they follow the path of diffraction spikes of bright stars. This means that they are some kind of ghost artifacts. They aren't always violet, they also green and blue. I sense that RGB color scheme play its role here. 😃
