This Friday asteroid 2012 DA14 will go down in the record books as the closest approach of an object of its size since astronomers began keeping records a few decades ago.
Zipping past our planet closer than most orbiting communication and weather satellites, this office building sized chunk of rock should be visible to some lucky skywatchers in the Eastern Hemisphere.
When the asteroid is at its closest at 19:24 UTC (2:24 p.m. EST/11:24 a.m. PST) it will be flying over the eastern Indian Ocean, off Sumatra (approx. latitude: -6 deg . South / longitude: 97.5 deg. East), according to NASA.
Unfortunately for folks in the Western Hemisphere this means it will be daylight and so predictions are that the best chances of catching a view will be from places like Africa and Asia after local nightfall on the 15th.
According to Universe Today, the best views will be from western Indonesia and Australia when the asteroid will be crossing the overhead sky in the hours before dawn, while folks in Australia and eastern Asia may see it gliding across the heavens much like a fast-moving satellite in the low eastern sky the morning of the 16th.
Although it technically should be bright enough to be easily seen with binoculars (magnitude 7.4), a small telescope is really your best hope. Looking a lot like a faint satellite, what will make hunting down DA14 so tricky, is the fact that it’s moving crazy fast across local skies- covering the moon disk’s width in less than a minute.

NASA will have coverage using a telescope at NASA’s Marshall Space Flight Center in Huntsville, Ala. from 6 p.m. to 9 p.m. ET on Friday.
There will also be a video feed by Slooh Space Camera from their telescopes on the Canary islands, off the west coast of Africa and in Arizona starting at 9 pm EST.
