It looks like you got it, but the situation is not as simple as it looks. At the time of your picture, 2003 EL61 (mag 17.5) was almost exactly at the location of a slightly brighter mag 17.1 star- the separation is only about 4". But the time of your CdC screen capture is about 1 hour later, by which time 2003 EL61 was so close to the star that the asteroid symbol in CdC covers the star. You might also need to use the "show more stars" icon to show the fainter stars.
Look closely at the image and you'll see two objects at the location indicated by CdC. The slightly brighter object on the left is the star. 2003 EL61 is fainter, a few pixels to the right and slightly up. If you "show more stars" in CdC, you'll also notice a mag 17.7 star barely showing in your image about 38" north and slightly east (left) of 2003 EL61 and the first star. -John --- Robert Vanderbei <[EMAIL PROTECTED]> wrote: > My understanding is that one of the 3 new planets announced a week or > two ago is designated > 2003EL61.
