Moon’s cycle of lighted shapes (phases) lasts 29.53 E. days, as the phases also depend on direction of sun (appears to move 30 degrees eastward each month along zodiac). The moon is seen about 13 days growing in the evening from a slender crescent ( ) ) to Full, followed by an equal time shrinking (mainly seen in the a.m. sky) and then 3 days hidden in sun’s glare. Key Moon Phases (D) moon ½ full in evening (best for crater & mountain viewing ) & (O) full moon (see all lava plains) (Dec. ’14, 6 -O, 28 – D)) // (Jan. ’15, 4 - O, 26 - D), // (Feb. ’15, 3 – O, 25 - D) // (Mar. 5 – O, 27 – D) (Apr. 4 – O, 25 – D), // ( May 3 – O, 25 - D) // (Jun., 2- O, 27 – D)) // (Jul., 1 – O, 24 –D, 31 –O (Blue Moon)) (Aug., 22 – D, 29 – O) // (Sep., 20 – D, 27 – O (Harvest Moon)) // (Oct. 20 – D, 27 – O (Hunters’ Moon)) // (Nov., 19 – D, 25 – O) // (Dec., 18 – D, 25 – O (Long Night Moon)) (D = ½ full, O = full) THE 5 BRIGHT PLANETS (Mercury, Venus, Mars, Jupiter & Saturn): Uranus, Neptune are much dimmer.

The Blue Hours Dusk, Early September, Just Beneath the Arctic
The Blue Hours Dusk, early September, just beneath the Arctic Circle, by a tideline glacier in East Greenland. The cusp of the seasons, the cusp of the globe, the cusp of the land, and the day’s cusp too: twilight, the blue hours. At this latitude, at this time of year, dusk lasts for two or three hours. We have returned from a long mountain day: pitched climbing up steep slabs and over snow slopes to a towered summit, from which height we could see the great inland ice-cap itself. Then down, late in the day, the darkness thickening around us, and the sun dropping fast behind the western peaks. So we sit together back at camp as the last light gathers on the water of the fjord, on icebergs, on the quartz seams in the white boulder-field above our tents. Twilight specifies the landscape in this way – but it also disperses it. Relations between objects are loosened, such that shape-shifts occur. Just before full night falls, and the aurora borealis begins, a powerful hallucination occurs. My tired eyes start to see every pale stone around our tent not as boulder but as bear, polar bear, pure bear, crouched for the spring. Across the Northern hemisphere, twilight is known as the trickster-time: breeder of delusion, feeder of fantasies, zone of becomings. In Greek, dusk is called lykophos, ‘wolf-light’. In Austria, too, it is Wolflicht. In French it is the phase entre chien et loup, ‘between dog and wolf’: the time when, as Chrystel Lebas has written, ‘it is nearly impossible to tell the difference between the howling sound coming from the two animals, when the domestic and familiar transform into the wild.’ I do not know the Greenlandic word for dusk, but perhaps it would translate as ‘bear-light’. -

Roadmap #84 Hardly Any Light ⏤ Which Means Much Slower Shutter Speeds As Well
BREAKFAST STOCK CLUB PREMIUM CHALLENGE #84 SEQUOIA CLUB Blue Hour By Marilyn Nieves Also known as the blue hour, twilight is what I call the magical hour of the day. As winter settles in and we experience shorter days, it’s the perfect time to have some fun with night photography. The blue hour comes twice a day. It’s called the blue “hour” but in reality, the average time frame is about 30 minutes, depending on your location. It happens just before sunrise and then again right after sunset. I typically go out to capture it in the evening as the sky’s blue deepens and you see hints of purple and magenta. As city lights turn on, their golden hues seem even more vibrant and eye- catching in contrast with the sky. No matter where you are, there’s just something wonderful and magical in blue hour images. It’s a sliver of the day that transforms everything we see. Twilight Images as Stock Blue hour images are not only eye- catching but they can create a mood of wonder, mystery, and exploration among viewers. Think of destinations from the perspective of the traveler and what would feel inviting and make you want to explore that place. Blue hour light can create some stunning stock images useful for travel related advertising projects. From a slightly more abstract point of view, with the aperture wide open to give you just a hint of the city, this image can be used in so many ways. For example, other than as a travel concept it can also be used as a broader conceptual business theme about looking towards the future and unlimited possibilities. -
When Does Sabbath Start &
WHEN DOES SABBATH START & END? Leviticus 23:32 “It shall be unto you a sabbath of rest, and ye shall afflict your souls: in the ninth day of the month at even, from even unto even, shall ye celebrate your sabbath.” ● Weekly Sabbath, New Moons, & High Sabbaths ALL START AT EVENING AND ENDS THE NEXT EVENING. HOW DO I KNOW WHEN IT IS EVENING? Genesis 1:5 “And God called the light Day, and the darkness he called Night. And the evening and the morning were the first day.” ● The daytime is when there is still light out. ● Evening is NIGHT TIME WHEN IT IS COMPLETELY DARK EXCEPT FOR THE MOON & STARS. ● The sun, moon, and stars were not created till Day 4 of creation see Genesis 1:14-19. SUNSET IS NOT WHEN SABBATH STARTS. SUNSET IS NOT WHEN NIGHT/DARKNESS STARTS. IT IS NOT COMPLETELY DARK TILL AFTER ASTRONOMICAL TWILIGHT WHEN THE SUN IS 18 DEGREES BELOW THE HORIZON WHICH IS KNOWN AS ASTRONOMICAL DUSK. ● Twilight is the time between day and night when there is light outside, but the Sun is below the horizon. There are three stages of twilight before it is NIGHT/DARK. 1. Civil Twilight, Dawn, and Dusk: Civil twilight occurs when the Sun is less than 6 degrees below the horizon. In the morning, civil twilight begins when the Sun is 6 degrees below the horizon and ends at sunrise. In the evening, it begins at sunset and ends when the Sun reaches 6 degrees below the horizon. ■ Civil dawn is the moment when the center of the Sun is 6 degrees below the horizon in the morning. -

The Above Are Lyrics Taken from the Tune Sunrise, Sunset —A Well-Known Song from the Theatrical Production Fiddler on the Roof
Yard and Garden - 02-02-2013 - Ted Griess / Extension Horticulture Assistant Sunrise, sunset Sunrise, sunset Swiftly flow the days. Seedlings turn overnight to sunflowers Blossoming even as we gaze. The above are lyrics taken from the tune Sunrise, Sunset —a well-known song from the theatrical production Fiddler on the Roof. Of late these lyrics have been bouncing around in my head, not because I’ve recently attended the theater; but, rather, I have been passionately observing the remarkable production Mother Nature has been providing us. I am reasonably sure this keen awareness is due to my dislike for winter and a longing for spring when I can again garden. As I arise in the dark each morning, I usually walk into my home office and check our outdoor thermometer. Observing how cold the outdoors temperature is, I generally utter a shivering “B-r-r” and head directly to our living room to light a fire in our fireplace. By the time a nice flame is flickering, Rita joins me with a hot cup of coffee and there we sit, enjoying the warmth, chatting and planning our day. Later, as the morning sun begins to rise above the horizon, I frequently find myself gazing out our windows to the east, marveling at the beautiful red and orange colors that streak across the gray-blue dawning sky. Sunrise in my backyard What a breath- taking sight it is, and how awe-struck I am. Fortunately, this amazing display often repeats itself near the end of the day— a miraculous spectacle we call sunset.
