This asteroid was discovered by LINEAR in Dec 9 1999.
Last night Oct 21 I got a few images of this asteroid.
The setup used was my remote observatory's 30cm SCT from Meade and the imager a SBIG ST-10XME with a resolution of 0.83"/px.
The asteroid was easily visible in the 300s exposure images in L filter.
In astrometrica we can see there is a small difference between the predicted red square and the true position in magenta.
From CoLiTec I got this nice animation of the asteroid.
Below we see the trail of the asteroid. I tried to stack the images in the asteroid position but unfortunately the asteroid was hidden behind a star trail.
