The February Night Sky

The sky is not a painting, it's a movie. Stars pulse, flare, some explode as supernova, asteroids whiz by the earth, new comets appear in the sky, Aurora sets the northern skies ablaze and meteors streak through Earth's atmosphere.

The Full Moon for February

The Full Snow Moon – February. Since the heaviest snow usually falls during this month, native tribes of the north and east most often called February’s full Moon the Full Snow Moon. Some tribes also referred to this Moon as the Full Hunger Moon, since harsh weather conditions in their areas made hunting very difficult.. Courtesy: Farmers Almanac.

February Visible Lunar Highlights

February 10, penumbral eclipse of the Moon, February 11, Regulus 0°.8 N. of Moon, After sunrise, February 20, Saturn 4° S. of Moon.

 

Faint penumbral eclipse of the Moon

February 10, 2017 the Full Moon occurs at 7:33 pm when the penumbral eclipse begins as the Moon cuts into the Earths shadow at 7:33 pm. At 7:43 pm maximum eclipse occurs and ends when the Moon leaves leaves the penumbra at 9:55 pm. Look closely and you may notice a a dark gray shading to the Moon’s northern limb. This is a subtle event and will not be easy to see the slight darkening of a portion of the Moon by the Earths shadow. This event is visible around sunset or early evening for most of the Americas.

COMETS

45P/Honda-Mrkos-Pajdusakova (2016)

The comet raveling at 51,000 mph, makes its closest approach to Earth at 3:00 am February 11th, 2017. The comet at 3:00 am will be about 25 degrees above the eastern horizon. Motion of the comet through a telescope is very obvious. The closest approach to Earth is on February 11th when the comet passes about 8 million (7818135.17930287) miles from Earth. The comet should be visible with binoculars. In a telescope it appears as a fuzzy object at about 7.9 magnitude.

See image below for position of comet on February11th at 3:00 am at RA: 16h 35m 55s Dec: +25°01'54". 

 

 The comet reached perihelion December 31, 2016. Comet 45P, was discovered by Minoru Honda in December 1948. This comet is a periodic comet and orbits the Sun once every 5.25 years.

The Sun

Real time solar wind dials are linked live to the ACE Spacecraft.

 If the dial on the left (Magnetic Field) has dipped below zero, the speed is high and the dial dynamic pressure is in the yellow/red, be alert for Aurora. Anytime the gauges are in the Red and the dial on the left, the Magnetic Field BZ has dipped to the yellow-red... Aurora will be occurring in our area. See link to solar wind gauge here: REAL TIME SOLAR WIND
