Potential satellite?

  • JG1987 by JG1987

    First, turn the view to black-hot (invert). Next, look at the largest star nearly centered in the picture (slightly left of center, but VERY slightly; also a hairsbreadth above the horizontal mid-line). There is a small star on the upper-right portion of the star; I am NOT talking about that. On the first frame, at the center-bottom of the star, there is some sort of small body. On the second frame, you will see the small body disappear from the center-bottom and reappear on the center-top. The position again changes back to the center-bottom on frame three, and it again changes back to the top on frame 4. Any idea what that could be? I am not sure where in the sky this is looking, nor do I know any sort of distance but, it would seem like some sort of satellite to the large star. Maybe another planet or a moon. Mainly, I am just wondering if this is trick of the camera or if that object exists and is legitimately orbiting that star.

    Are only sensor pixels saturated by the brightness of the star

    the star you are talking about is tycho 2 226-290-1 its to the right at 90.23 degrees of hydra.

    its exact location is Center (RA, Dec): (137.418, 2.172)

    Center (RA, hms): 09h 09m 40.293s

    Center (Dec, dms): +02° 10' 19.272"

    Size: 10.7 x 10.7 arcmin

    Radius: 0.126 deg

    Pixel scale: 2.51 arcsec/pixel

    Orientation: Up is 180 degrees E of N

    at 2.51 pixels its quite large so could well a little bleeding on the camera which is causing the lumps on the star.
