[Diagram]
This diagram shows the close passage of 2004 BL86 on January 26, 2015.
The view is nearly edge-on to the Earth's orbit; the Moon's nearly circular
orbit is highly foreshortened from this viewpoint. The asteroid moves
from the south to the north, from below the Earth's orbit to above. The
indicated times are Universal Time. Closest approach occurs at about 16:19
UTC, or about 11:19 EST. The roughly 500-meter (1500-foot) asteroid approaches
to within 1.2 million kilometers (750,000 miles) of Earth, or about 3.1
times the distance of the Moon.

The track of asteroid 2004 BL86 as viewed from the Earth, plotted on a
star chart with an equatorial coordinate grid. The asteroid location is
shown at four-hour intervals from January 26 to 28. The indicated times
are Universal Time; subtract 5 hours for Eastern Standard Time (EST),
6 hours for CST, and 8 hours for PST. On January 26, the asteroid will
pass within 11 degrees of Jupiter, now shining brightly in the east in
the evening sky.

This view shows the two-day track of 2004 BL86 relative to a local horizon
at 9 pm in the evening, as seen from locations in the contiguous United
States. On the evening of January 26, the asteroid will pass near a brightly
shining Jupiter in the eastern sky, about 11 degrees higher relative to
the eastern horizon. Cardinal directions are given along the bottom. The
times given on the asteroid track are in Universal Time; subtract 5 hours
to obtain Eastern Standard Time (EST), 6 hours for CST, 8 hours for PST.
