The asteroid designated 2003 UV11 was discovered on October 21, 2003 by B. Skiff during the LONEOS survey with a 0.59-m Schmidt. According to its absolute magnitude (H=19.3) this object has an estimated diameter of roughly 400-500 meters, so it is a relatively large near-Earth asteroid. 2003 UV11 will have a close approach with Earth on 2010 October 30 when it will be within 0.013 AU (~5 lunar distances). The asteroid will reach a magnitude around 12 over the next few days (28/30 October 2010), becoming an easy target for small-medium sized telescopes + ccd.We have been able to follow-up 2003 UV11 on October 28 at 07:00UT (01:00am local time) through the GRAS network, using a scope located in Mayhill (NM).
