will be a total eclipse of the sun on August 21. It will be
visible in a 70 mile-wide band that stretches from Oregon to South
Carolina. Here on Hatteras Island, we will have a partial
eclipse. The moon will cover 89% of the sun. The moon will start
to block the sun at 1:30 p.m. The peak of the eclipse will be at
2:51 p.m. and the event will end at 4:10 p.m. If you want to see the
total eclipse, you should plan on traveling to South Carolina or
western North Carolina. If you plan on traveling to see the eclipse,
get there early and plan on staying late. There are estimates that as
many as 20 million people might drive to see this once-in-a-lifetime
you, your family, or any of your friends intend to view the eclipse,
you should purchase special sunglasses that have an ISO12312-2
certification. Apparently, there are “solar viewers” being sold
that are not in compliance with this standard! That means using
them to view the eclipse could result in severe damage to your eyes,
American Astronomical Society has verified that solar viewers and
eclipse glasses from American Paper Optics, Baader Planetarium
(AstroSolar Silver/Gold film only), Rainbow Symphony, Thousand Oaks
Optical and TSE 17 comply with an ISO12312-2 certification. You can
find most of these products on Amazon and they are pretty
inexpensive! So take the time to order a 5- or 10-pack today and
protect your eyes!

other monthly astronomical events, Jupiter starts the month visible in
the SW at dusk. By the end of August, it will start getting
close to the western horizon and only be visible for about an hour.
Saturn will start the month in the SSE. It will be visible in the evening skies throughout August.
will be visible near the Eastern horizon in the early morning hours.
Throughout the month, it will rise just around 4:00 a.m.
Mercury will be visible near the Western horizon just after sundown for the first week of the month.
Neptune will rise in the East just after 9:00 p.m. on August 1.
will rise at 11:30 p.m. Normally, I don’t recommend looking for it
with the naked eye, but given the current state of emergency and
reduction of light pollution, there is a chance you might spot it on a
very clear night.
Pluto will be in the night skies for all of August too, but don’t expect to see it.
Perseids Meteor shower will peak the night of August 11-12. This
meteor shower is known to have up to 100 shooting stars per hour.
It is also famous for its fireballs. Best viewing will be between
midnight and dawn.
is M 27, the Dumbbell Nebula. It is also known as the Apple Core
Nebula. It is about 1400 light years away and has a visual
magnitude of +7.1. Charles Messier discovered it in 1764.
In 1784, William Herschel thought the circular shape was similar to his
recently discovered planet, Uranus, and dubbed M 27 a “Planetary
Nebula,” creating a new class of deep sky objects. There are about
2,000 known Planetary Nebula.
