Rare phenomenon: Mercury will transit the Sun Nov 11. Visibility in Greece

A rare phenomenon visible in Greece: the innermost planet of our solar system, the Mercury will transit the sun on Monday, November 11, 2019.  Mercury will pass directly in front of the sun and be visible through telescopes with solar filters as a small black dot crossing the sun’s face.

It’ll be visible in part from most of Earth’s globe. The entire transit is visible from South America, eastern North America, and far-western Africa.

The last transit of Mercury was in 2016. The next one won’t be until 2032.

Visibility in Greece:

Mercury will come into view on the sun’s face at 02:35 p.m. local time and its transit journey will last 5 and a half hours. It will exit the sun’s face at 08:04 p.m.

Its visibility in Greece ends at 05:20 p.m short before the sunset.

 

According to earthsky.org, You need a telescope and solar filters to view the transit. Mercury’s diameter is only 1/194th of that of the sun, as seen from Earth. That’s why the eclipse master Fred Espenak recommends using a telescope with a magnification of 50 to 100 times for witnessing the event.

Unless you are well-versed with the telescope and how to properly use solar filters, we advise you to seek out a public program via a nearby observatory or astronomy club. Never look at the sun through a telescope.

Worldwide map of where the Mercury transit is visible.

What part of Earth will see the November 11 transit of Mercury? As shown on the worldwide chart above, the transit will be visible (at least in part) from most of the globe, with the exception of the shaded-out portion (Indonesia, most of Asia, and Australia). Mercury takes some 5 1/2 hours to cross the sun’s disk, and this transit of Mercury is entirely visible (given clear skies) from eastern North America, South America, the southern tip of Greenland, and far-western Africa.

For North America, the transit begins in the early morning hours on November 11. The eastern part of North America sees the start of the transit after sunrise November 11, whereas the western part sees the transit already in progress as the sun rises on November 11.

As for the world’s Eastern Hemisphere – Africa, Europe, and the Middle East – the transit starts in the early afternoon November 11 in the westernmost parts of Africa and Europe, and in the late afternoon November 11 in eastern Europe and the Middle East. In New Zealand, the transit is in process as the sun rises on November 12.
