On April 28th and 29th, there will be an annular solar eclipse, when the Sun passes behind the Moon. Since the disk of the Moon will appear smaller than the disk of the Sun, it will create a “penny on nickel” effect, with a fiery ring of sunlight shining around the Moon’s dark silhouette, unlike a total solar eclipse, during which the entire Sun is hidden by the Moon.
Don’t dig out your eclipse glasses just yet, though. It is quite possible that only penguins will witness the annular (ring) phase of this eclipse, as it will occur within the uninhabited region of Wilkes Land in Antarctica. A partial eclipse will be visible only from Australia.
Because the axis of the Moon’s antumbral shadow misses the Earth and only its edge grazes Antarctica, an accurate prediction of the duration of annularity is all but impossible. This is the reason that the duration of annularity in the table below is given as 0 minutes and 00 seconds.
Partial Eclipse Begins: 11:53 p.m., April 28 – Annular Eclipse Begins: 1:58 a.m., April 29 – Greatest Eclipse: 2:03 a.m. – Annular Eclipse Ends: 2:09 a.m. – Partial Eclipse Ends: 4:14 a.m. – Maximum Duration of Annularity: 0m 00s
Though no one lives within the visibility zone for this eclipse, if you happen to be in Antarctica that night, the most important thing to keep in mind when viewing the Sun, including during the ring phase is to never look directly at even a portion of the Sun without proper viewing glasses.
