In the Sky This Month - March 2021 - Rick Wagner

01 Mar - bright Mars passes several degrees south of
the Pleiades star cluster. Mars makes a very
photogenic pass between the Pleiades and the Hyades
clusters over the ~10 days. Perfect chance to sketch
the motion for the Orbital Motion requirement of the
Explore the Universe certificate.

01-15 Mar - Zodiacal light is visible in the west
towards the end of evening twilight as a faint and hazy
triangular pillar of light extending upwards from the
western horizon towards the Pleiades.


04 Mar - asteroid 4 Vesta at opposition in the hindquarters
of Leo the lion. At magnitude 6.0 it might be
barely visible to the naked eye for the more eagle-eyed
of us. Vesta is the only minor planet which is ever
visible to the naked eye for most people.


04 Mar - Algol at minimum about 20:10


05 Mar - Mercury (mag 0) is less than a degree north
of Jupiter (mag -2) very low in the ESE sky starting
about 45 minutes before sunrise. At the same time all
4 Galilean moons of Jupiter will be in a line on the
west side of the planet - visible in carefully held
binoculars and small telescopes. Saturn (mag 1) is 9
degrees to the upper right of Jupiter.


06 Mar - Last quarter Moon


06 Mar - Mercury at greatest elongation west low in
the eastern sky in morning twilight


09-11 Mar - crescent Moon passes about 4d south of
Saturn then Jupiter and then Mercury low in the
eastern sky in morning twilight

13 Mar - William Herschel discovered Uranus 240 yrs
ago today - take your binoculars or telescope out to
look at it after evening twilight and celebrate the
anniversary!


14 Mar - 0200 Daylight saving time begins, clocks
spring ahead


18 Mar - Mars and the Moon are near the Hyades and
Pleiades star clusters.

overhead at the equator and we get (roughly) equal
hours of daytime and nighttime.

and devices and get out to look at the sky!
