Imaging on Jan 18, 2003
at Jan 21 Coordinates

I took 6 * 20 minutes images tonight for Jan 21 coordinates, 3 hours of telescope time. I shifted the coordinates a little bit for each frame so the stars don’t register on the same spot on the CCD twice. This should help in determining if a certain anomaly is CCD related or something else. Imaging times are UT:

Frame1 5:55:26
Frame2 6:29:27
Frame3 6:56:23
Frame4 7:23:06
Frame5 7:53:06
Frame6 8:18:46

 

Actual coordinates used are in this picture showing the random locations that I chose.

Frame1: RA 4.36007 Dec 12.11875, or RA 4 21 36.252 Dec 12 07 07.5 (Jan 21, 2003 Coordinates)
Frame2: RA 4.360555 Dec 12.110555, or RA 4 21 38 Dec 12 06 38
Frame3: Ra 4.3624897 Dec 12.11345833, or RA 4 21 44.963 Dec 12 06 48.45
Frame4: RA 4.36117138 Dec 12.10981111, or RA 4 21 40.217 Dec 12 06 35.32
Frame5: RA 4.3597183 Dec 12.1307777, or RA 4 21 34.986 Dec 12 07 50.80
Frame6: RA 4.36252777 Dec 12.11681666, or RA 4 21 45.1 Dec 12 07 00.54

 

Planet X has no excuse to dance with the camera this time.

Naji, you did the right way! (Taking each frame with a little shift.)

Once again, these are FITS files, which means one must use a FITS viewer which can be downloaded from a Harvard site. The files are dated Jan 18th, taken in the clear skies of Arizona. The Coordinates for Jan 21, 2003 have been Converted. Use Pierre's Precise Finder or Naji's Direction Guide to locate the coordinates in reference to neighboring stars, including the large SAO star used for orientation on the Sep 21, 2002 imaging.
