Third Contact

[Whitters]

When observing and making manual timings from the web cam image I came with a figure of 11:04:32 UT but when I had time to review the CCD images it was obvious that I was way off, more then 28 seconds later than the time as recorded by the CCD image. (Image times are automaticaly recorded in the FITS header of the CCD image) Unsing the Open2 calculator a 3rd contact of 11:04:32UT gives an AU of 157.8 million km while the CCD timing of 12:04:04UT gives a distance of 149.94 million km.
