 This object was measured for only about 20 minutes due to cloud cover.  The skies were "patchy" and I was working through the haze.

 Not a good night for observing.  A total of 30 - 30 second exposures were collected and then divided into three groups of ten for stacking.

 An object fainter than this would have been nearly impossible to image with the sky conditions.

Total CCD imaging time:  15 minutes over a period of 20 minutes

Total time spent on this object:  30 minutes

2002 TC9 (identified in black) shared the same FOV with asteroid 54444 (identified in white).

Both objects were comparable in magnitude.  17.4 - 17.6

Notice in the top image, asteroid 54444 is not clearly visible due to the image stacking techniques.
