2024?\u00a0 As this is being written, the first true winter-like weather is finally blanketing the Ontonagon area with enough snow to finally cover the mower lines still visible in neighboring yards.\u00a0 According to <\/span><i><span style=\"font-weight: 400;\">Keweenaw Reports<\/span><\/i><span style=\"font-weight: 400;\">, the last time the Copper Country had this little snow in January was back in 1931 &#8211; a winter with a decidedly below average snowfall of a little over 90 inches.\u00a0 What a difference a year can make.\u00a0 One only needs to remember that area churches were forced to cancel Christmas Services in 2022 due to a deadly blizzard that brought high winds and heavy snowfall.\u00a0 While the lack of snow has certainly been a downer for the tourist industry, the fleet of snowmobile plying the trails in the last weeks of January gives us hope they can make up for some of the lost revenue.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u00a0\u00a0\u00a0\u00a0\u00a0No matter what the weather is doing as January turns to February, the astronomical events for the month will not be canceled due to continued winter-like weather.\u00a0 We begin this month 41 days past the Winter Solstice meaning we have already gained back almost 23 percent of the daylight hours we were living without in December.\u00a0 Extended daylight hours and milder winter conditions are a sure way to help us get outdoors and avoid the seasonal blahs some experience during the longest nights of early winter.\u00a0 Being a Leap Year, the extra day tacked on to February also means we are starting the month only 50 days away from the Spring Equinox.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u00a0\u00a0\u00a0\u00a0\u00a0<\/span><b>Venus <\/b><span style=\"font-weight: 400;\">and <\/span><b>Mars <\/b><span style=\"font-weight: 400;\">will be visible low in the ESE sky one hour before sunrise.\u00a0 The Abrams Sky Calendar tells us binoculars may be useful for viewing them in the growing light of dawn.\u00a0 While Venus will still be bright (mag -3.9), Mars will be much dimmer (mag +1.3).\u00a0 Venus will continue to sink into the morning sky and soon have a close conjunction with Mars (on Feb 22) and Saturn (March 21).\u00a0 In early February, it may also be possible to see <\/span><b>Mercury<\/b><span style=\"font-weight: 400;\"> (mag -0.3) to the lower left of Mars in the bright twilight of morning.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u00a0\u00a0\u00a0\u00a0\u00a0<\/span><b>Jupiter<\/b><span style=\"font-weight: 400;\"> starts the evening high in the SW sky and its magnitude will decrease from -2.4 to -2.2 during the month (remember, the lower the number, the brighter the object).\u00a0 Clear cold nights this month make for excellent observing of Jupiter as it crosses the expanse of the sky during the night.\u00a0 <\/span><b>Uranus<\/b><span style=\"font-weight: 400;\"> (mag 5.7 to 5.8) will be tougher to locate to the upper left of our nearest Gas Giant, about10 degrees ENE of Jupiter.\u00a0 It may be easier to find by using the 4.3 magnitude star <\/span><b>Delta <\/b><span style=\"font-weight: 400;\">in<\/span><b> Aries the<\/b> <b>Ram.\u00a0 <\/b><span style=\"font-weight: 400;\">Uranus will be just below Delta Ari and on Feb 15, just to the left of the (almost) <\/span><b>First Quarter Moon<\/b><span style=\"font-weight: 400;\">.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<\/span><b>Saturn<\/b><span style=\"font-weight: 400;\"> is the only notable planet in the evening sky at present.\u00a0 It can be seen low in the WSW 40 minutes after sunset.\u00a0 The very <\/span><b>Young Crescent Moon <\/b><span style=\"font-weight: 400;\">\u00a0will be just below the Ringed Planet on February 10.\u00a0 Saturn will drop from our view on Feb 14 so our observing challenge for this month is to note which date you can last see Saturn before it disappears from view.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u00a0\u00a0\u00a0\u00a0\u00a0The <\/span><b>Last Quarter Moon<\/b><span style=\"font-weight: 400;\"> of the old cycle takes place on Feb 2 and the <\/span><b>New Moon <\/b><span style=\"font-weight: 400;\">of the new cycle happens on Feb 9.\u00a0 The <\/span><b>First Quarter Moon <\/b><span style=\"font-weight: 400;\">is slated for Feb16 and the <\/span><b>Full Moon<\/b><span style=\"font-weight: 400;\"> will grace our skies on February 24.\u00a0 The Moon will reach its apogee, or farthest distance from the <\/span><b>Earth<\/b><span style=\"font-weight: 400;\"> on Feb 25 when it will be 252,470 miles from our home world.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u00a0\u00a0\u00a0\u00a0\u00a0From February 27 to March 10, you may be able to observe the <\/span><b>zodiacal light<\/b><span style=\"font-weight: 400;\"> in the west just after the end of evening twilight.\u00a0 According to our friends at Wikipedia, \u201czodiacal light is a faint glow of diffuse sunlight scattered by interplanetary dust.\u00a0 It is brighter around the Sun and appears in a particularly dark night sky to extend from the Sun\u2019s direction in a roughly triangular shape along the zodiac.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u00a0\u00a0\u00a0\u00a0\u00a0Our historical event for this month might as center on the origin of this thing we call a <\/span><b>Leap Year <\/b><span style=\"font-weight: 400;\">(also known as an intercalary year or a bissextile year).\u00a0 A leap year is necessary to keep out calendars in step with the Earth\u2019s 365.25 day orbit.\u00a0 Without adjusting for the additional quarter day it takes the Earth to complete one orbit of the Sun, our calendar would slip one day out of sync every four years and an astounding 25 days every century.\u00a0 Intercalating (inserting) and additional leap day corrects the \u2018calendar drift\u2019 this physical property of our <\/span><b>Solar System<\/b><span style=\"font-weight: 400;\"> would impart on our dating system.\u00a0 A leap year occurs in each year that is evenly divisible by 100, but not by 400.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u00a0\u00a0\u00a0\u00a0\u00a0\u201cThe term \u2018leap year\u2019 probably comes from the fact that a fixed date in the Gregorian calendar normally advances one day of the week from one year to the next.\u00a0 The day of the week in the 12 months following the leap day (from March 1 through February 18 of the following year) will advance two days, thus \u2018leaping\u2019 over one day in the week.\u00a0 Christmas Day of 2023, for example, fell on a Monday while it came on a Sunday in 2022.\u00a0 In 2024, it will \u2018leap\u2019 over Tuesday thus putting December 25 on a Wednesday.\u201d\u00a0 Thank you (again) to Wikipedia for the above explanation.\u00a0 Don\u2019t forget that the Summer Olympics and United States Presidential elections also occur in leap years.\u00a0 We remain optimistic that world strife will not unhinge this Olympic cycle (it has happened) and the march of democracy in the United States (a hallmark of our great nation) will continue forward \u2018for our children\u2019s children\u2019s children\u2019 (yes, I borrowed this from the Moody Blues).<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u00a0\u00a0\u00a0<\/span><span
