A sudden burst of light called a satellite flare will be visible in the sky in the early morning of March 30, 2014 (Sunday) as a satellite named Iridium 37 directs sunlight towards ground through one of its large reflective antennas. Even with just the naked eye, observers should see the satellite emerge from the northern horizon at around 5:16 am, slowly climb as it reaches overhead (zenith) at 5:23 am, and continue to brighten up as it moves southward reaching its peak brightness at around 5:24 am (Philippine Standard Time), positioned approximately 50 degrees above the southern horizon then eventually fade and disappear at around 5:30 am.

The illustration shows how the sky will look like on March 30, 2014 during a predicted sudden brightening (or flare) of a satellite (named Iridium 37) at around 5:24 am (Philippine Standard Time), approximately 50 degrees above the southern horizon. Satellite flares are caused by sunlight bouncing off a satellite’s reflective surface like antenna or solar panels acting as giant space mirrors directing sunlight towards the ground, with peak brightness lasting for several seconds. Map of the sky generated using Stellarium.

Aside from the satellite, naked-eye objects such as the Moon, Venus, and Mercury will also be visible in the eastern horizon, as well as Saturn and Mars in the western horizon. For a detailed map of the sky (generated by Heavens-Above) that shows the path of the satellite, click here.

The International Space Station (ISS) currently orbiting approximately 400 kilometers above the Earth’s surface will treat us with yet another spectacular sight on the early morning of November 11, 2012, as it zooms past, for the second time this week, above the Philippines.

The satellite will be visible to us because its solar panels will be geometrically well-placed to reflect sunlight towards the ground, acting like giant space mirrors. From the ground, it will look like a very bright flare coming from the southwestern horizon and then slowly (much like an airplane) move towards the north-northeastern horizon until it disappears from view. It will be visible for approximately 6 minutes, from 04:57:09 am to 05:05:49 am and will be visible to the naked eye. No special equipment is required to observe the satellite flyby. For previous ISS observations, click here.

Satellite flares are caused by the reflective surfaces on satellites like antennas and solar panels acting as a giant mirrors in space, reflecting sunlight directly towards the Earth,  seen from the ground as a bright “flare” that could last for a few seconds. More Iridium flare images here.
