present:\u00a0 As of January 1, we have now regained 6 percent of our lost daylight hours.\u00a0 We won\u2019t really notice the \u2018extra daylight\u2019 for a couple of weeks, but rest assured, the Sun is inching higher in the sky each day and in less than three months, we will already be halfway to the traditional beginning of Summer.\u00a0 The twelve hours of daylight and darkness we will see on the Vernal (or Spring) Equinox gives us hope of warmer weather to come, but perhaps not so much a happy event for the Winter sports lovers out there.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u00a0\u00a0\u00a0\u00a0\u00a0We begin our planetary viewing this month with brilliant <\/span><b>Venus<\/b><span style=\"font-weight: 400;\"> which will occupy the SW to WSW horizon for about 1.3 hours early in the month to 2.0 hours by the end of January.\u00a0 Shining at magnitude -3.9, it will be very easy to locate.\u00a0 The next brightest planet, <\/span><b>Jupiter<\/b><span style=\"font-weight: 400;\">, will stand at -2.4 to -2.2 well up in the S to SW sky at dusk where it can be seen for nearly seven hours before it sets.\u00a0 Next in magnitude will be -1.2 <\/span><b>Mars<\/b><span style=\"font-weight: 400;\">.\u00a0 The <\/span><b>Red Planet<\/b><span style=\"font-weight: 400;\"> begins the new year in the east and will ascend to a higher point in the ESE by Jan 31.\u00a0 <\/span><b>Saturn<\/b><span style=\"font-weight: 400;\"> will rank fourth in brightness in January at +0.8.\u00a0 The <\/span><b>Ringed Planet<\/b><span style=\"font-weight: 400;\"> begins the month 24 degrees (or two and one half closed fists) to the upper left of Venus but it will will close one degree per day so by Jan 22, they will only be 21 arcminutes apart (about one third of a degree).\u00a0 Saturn will then be situated to the right of Venus after it passes by and continues to sink closer to the horizon with it setting 1.1 hours after sunset on Jan 31.\u00a0 A good observing challenge for early in the new year would be to see on what date you will be able to observe Saturn before it slips from view.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u00a0\u00a0\u00a0\u00a0\u00a0As for the faint planets at nightfall (<\/span><b>Neptune <\/b><span style=\"font-weight: 400;\">and <\/span><b>Uranus)<\/b><span style=\"font-weight: 400;\">, more information can be found by visiting the Sky Calendar extras page at <\/span><i><span style=\"font-weight: 400;\">abramsplanetarium.org\/msta\/ .\u00a0 <\/span><\/i><b>Mercury<\/b><span style=\"font-weight: 400;\"> will pass inferior conjunction on Jan 7 and brighten to mag +1.1 by Jan 15 and 0.0 on Jan 22.\u00a0 Mercury will be the highest in the ESE to SE morning twilight around Jan 24 and will reach its greatest elongation of 25 degrees from the Sun on Jan 30.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u00a0\u00a0\u00a0\u00a0\u00a0The first <\/span><b>Full Moon <\/b><span style=\"font-weight: 400;\">of 2023 will take place on Jan 6 with the <\/span><b>Last Quarter <\/b><span style=\"font-weight: 400;\">following on Jan 14.\u00a0 With the <\/span><b>New Moon<\/b><span style=\"font-weight: 400;\"> ending one Lunar Cycle and beginning the next on Jan 21, the first <\/span><b>Young Crescent Moon<\/b><span style=\"font-weight: 400;\"> will peek from low in the SW to WSW horizon 40 minutes after sunset on Jan 22 with Jan 28 marking the <\/span><b>First Quarter Moon.\u00a0 <\/b><span style=\"font-weight: 400;\">During the times when the Crescent Moon can be seen in areas with good dark sky viewing conditions, it may be possible to see a phenomenon known as <\/span><b>Earthshine.<\/b><span style=\"font-weight: 400;\">\u00a0 Earthshine can be observed when Sunlight reflecting off the Earth illuminates the darkened side of the Moon.\u00a0 It normally takes light about 9 minutes to travel the 93 million miles from the Sun to the Earth, but the light we see during Earthshine adds nearly 500,000 miles to the light we see shining off the dark side of the Moon.\u00a0 Those readers with a mathematical bent should be able to figure how much longer Earthshine light takes to finish its journey.\u00a0\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u00a0\u00a0\u00a0\u00a0\u00a0On Jan 30-31, observers along the southern states will see an <\/span><b>occultation <\/b><span style=\"font-weight: 400;\">of Mars by the Moon (in other words the Moon will pass between the Earth and Mars).\u00a0 Farther north, viewers will see the Moon pass just south of Mars.\u00a0 For the Great Lakes region, the closest point between the two bodies will take place between 12:38 a.m. and 1:27 a.m. EST<\/span><b>.\u00a0 <\/b><span style=\"font-weight: 400;\">A U.S. map and timetable for additional viewing sites can be found on the extra content page mentioned earlier.\u00a0\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u00a0\u00a0\u00a0\u00a0\u00a0Let us take a couple of moments this month to remember the announcement of Miss Mitchell\u2019s Comet.\u00a0 Maria (pronounced muh <\/span><i><span style=\"font-weight: 400;\">rye<\/span><\/i><span style=\"font-weight: 400;\"> ah) Mitchell discovered her comet in October of 1847 and the find was released in <\/span><i><span style=\"font-weight: 400;\">Sillman\u2019s Journal<\/span><\/i><span style=\"font-weight: 400;\"> in January 1848 under her father\u2019s name.\u00a0 The following month, she submitted the calculations of the comet\u2019s orbit under her own name.\u00a0 The disparity of opportunities for women astronomers (and scientists in general) led Miss Mitchell to become a staunch advocate for women&#8217;s rights.\u00a0 She was the first American and first woman to be awarded a gold medal prize as the \u2018first discoverer\u2019 of a comet by King Christian VIII of Denmark.\u00a0 Miss Mitchell\u2019s Comet was independently discovered by Francesco de Vico two days after Mitchell discovered it, but he reported it to European authorities.\u00a0 When the data was compared to the American report, Mitchell was verified as the first discoverer and awarded the gold medal.\u00a0 Mitchell\u2019s was the third cometary find attributed to a woman after Carloline Herschel and Maria Margarethe Kirch.\u00a0 Until next time, enjoy the extended early sky observing offered by our long January nights.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u00a0\u00a0\u00a0<\/span><span style=\"font-weight: 400;\">Compiled by
