Close Approach of Asteroid 2014 SC324

The asteroid 2014 SC324 was discovered (at ~ magnitude +21.4) on 2014, September 30.2 by Mt. Lemmon Survey (MPC code G96) with a 1.5-m reflector + CCD. 

2014 SC324 has an estimated size of 40 m - 90 m (based on the object's absolute magnitude H=24.1) and it will have a close approach with Earth at about 1.5 LD (Lunar Distances = ~384,000 kilometers) or 0.0038 AU (1 AU = ~150 million kilometers) at 1921 UT on 2014, October 24. This asteroid will reach the peak magnitude about +13.6 at close approach.

We performed some follow-up measurements of this object on 2014, October 24.3 remotely from the H06 iTelescope network (New Mexico, Mayhill) through a 0.25-m f/3.4 astrograph + CCD and a 0.1-m f/5.0 astrograph + CCD. Below you can see our image taken with the asteroid at about magnitude +13.6 and moving at ~ 135 "/min (the asteroid is trailed in the image due to its fast speed). At the moment of its close approach on Oct 24 at 1921 UT, 2014 SC324 will move at ~ 221 "/min. Click on the image below to see a bigger version. North is up, East is to the left.
