APRIL 2004 Chiamavi 'l cielo e'ntorno vi si gira, mostrandovi le sue bellezze etterne* Welcome to the Celestial Navigation Net! Celestial Navigation is the art and science of finding your way by the sun, moon, stars, and planets, and, in one form or another, is one of the oldest practices in human history. This webpage is an attempt to bring together all of the best Celestial Navigation resources on the internet, with pointers to other resources as well. Find out why we should study Celestial navigation in the age of GPS; get an introduction to Celestial Navigation's history, then take a look at the navigational astronomy page as a background for the theory and practice; teachers, discover how celestial navigation can enliven the classroom, whether your field is earth science, astronomy, math, history, or literature, with special links about Vikings; learn about navigational instruments, including sextants, astrolabes, nocturnals, and planispheres; learn about nonwestern, noninstrument Polynesian starpaths and Wayfinding; read quotations about navigation; check out some schools; or just go directly to the list of resources which lists the sources from the other pages. Other links of interest are here. *The heavens call to you and circle about you, displaying to you their eternal splendors...."

He wrote, "This nautical poem by Mr. E. Plumstead, an ardent defender of lunar observations, was taken from a popular old English navigation book titled Wrinkles by S.T.S. Lecky, master mariner, it being the 2oth edition...This book was given to me nearly fifty years ago by a cousin, Captain Tom Kelley, of West Tremont, on Mount Desert Island, Maine." There was a time when Parallax and dear old Mrs. Moon Were understood by seamen, and esteemed a precious boon. Then Wrinkles came; Edition Nine burst forth mid jubilation, Waxed fat and kicked, and then ensued the following conversation: "Pack up! Clear out!" said Wrinkles, "Take notice now, and mind, Both Parallax and you to Coventry we've consigned." "Who's We?" retorted Mrs. Moon, "I've never heard such fudge; Are you the We? Have I no friends? Are you the only judge?" "You've hit it off," said Wrinkles, "I am the We, far famed: You've lost your ancient following, of your conduct they're ashamed, Except a few 'Old Timers,' who from sundry dark recesses Sing your praises in the papers, have no names, give no addresses." "That's rather neat," replied the Moon, "But will you have the kindness Just to state the cause of this revolt, and why this modern blindness To the virtues that I still possess? Explain the situation. What has blighted all my virtues? Who has spoiled my reputation?" "Where have you been? What have you learned?" said Wrinkles, "Don't you know What happened here - it must be near a century ago? You've heard of Sextant, Compass, Log, Mercurial Barometer; Tremble! a goddess has been born. We've christened her Chronometer. "Behold my love, is she not fair? so strong, so plump, so pliable." "All Tommy Rot," replied the Moon, "I'll bet she's not reliable." "Alas!" said Wrinkles, "I know that; for has it not been noted, http://www.celestialnavigation.net/wrinkles.htm (1 of 2) [9/6/2004 12:50:46 PM] July To her most eccentric conduct my best chapter's been devoted? "Had you but read what I have said on her merits and demerits In Chapter Four, not for one hour would you maintain your spirits; Could I but show you Wrinkles your appearance would cease, You'd for ever hide your 'bloomin' cheek,' for ever hold your peace." "Of Wrinkles, sir," replied the Moon, "we've several copies here; But the chapter headed Lunars is the one we hold most dear. With equal care we've read them both; compared our notes and reckoned. No mortal who believed the first could understand the second. "Tis just about twelve months ago, I said to some inquirers, 'You had no power to banish me, I still had some admirers.' Adieu! dear boy. I'm off. Good night. To Coventry? No! Never! Let 'Wrinkles' come, Chronometers go, but I go on for ever." • Home • Why Celestial Navigation? • History • Navigational Astronomy• The Theory • The Practice • Celnav in the Classroom • Vikings • Navigational Instruments • Wayfinding • Schools • Quotations • Resources • Dante • Other Links • Webmistress • http://www.celestialnavigation.net/wrinkles.htm (2 of 2) [9/6/2004 12:50:46 PM] Recent Additions Recent Additions NEW!!!

Put in the "at" symbol for the word "at." obviously! People have been getting emails with viruses attached that APPEAR to be from me, but I am actually the victim of a return address highjack. This kind of virus goes on to someone's system, then sends emails that appear to be FROM someone who is in their address book. So someone out there with the original webmistress address needs to update their virus software ASAP! SECOND: It is with great sorrow that I report that Captain Ted Spurling Sr., to whom this site is dedicated and without whom it would not have existed, died earlier this year. It is he who gave me the poem in defense of lunars, "Wrinkles." Captain Spurling was the kindest and most interesting man on the Maine island I call my second home, with many, many years of experience in celestial navigation.

Moon Observations The months as we know them (January, February, etc.) are solar, based on how many days it takes the earth to revolve around the sun, roughly divided by twelve. A moon-th, or lunar (moon) month, is based on how long it takes the moon to orbit around the earth. The phases (shapes) of the moon change according to its cycle as it rotates around the earth, and the position of the moon with respect to the rising or setting sun. This cycle lasts about 29 ½ days. A (moon) month starts on “day one” with a new moon. The sun and the moon are in the same position and rise and set together. We can’t see the new moon. New Moon The moon rises and sets roughly 50 minutes later each day. The moon appears to “grow” or it waxes each day from a new moon to a full moon. The waxing moon’s bright side points at the setting Waxing sun and can be seen in the late afternoon on a clear day. Crescent A crescent moon is between new and half (less than half full), and may be waxing or waning. First Quarter The half-moon waxing or first quarter moon occurs about a week after the new moon.

  • Moons Phases and Tides
    Moon’s Phases and Tides Moon Phases Half of the Moon is always lit up by the sun. As the Moon orbits the Earth, we see different parts of the lighted area. From Earth, the lit portion we see of the moon waxes (grows) and wanes (shrinks). The revolution of the Moon around the Earth makes the Moon look as if it is changing shape in the sky The Moon passes through four major shapes during a cycle that repeats itself every 29.5 days. The phases always follow one another in the same order: New moon Waxing Crescent First quarter Waxing Gibbous Full moon Waning Gibbous Third (last) Quarter Waning Crescent • IF LIT FROM THE RIGHT, IT IS WAXING OR GROWING • IF DARKENING FROM THE RIGHT, IT IS WANING (SHRINKING) Tides • The Moon's gravitational pull on the Earth cause the seas and oceans to rise and fall in an endless cycle of low and high tides. • Much of the Earth's shoreline life depends on the tides. – Crabs, starfish, mussels, barnacles, etc. – Tides caused by the Moon • The Earth's tides are caused by the gravitational pull of the Moon. • The Earth bulges slightly both toward and away from the Moon. -As the Earth rotates daily, the bulges move across the Earth. • The moon pulls strongly on the water on the side of Earth closest to the moon, causing the water to bulge. • It also pulls less strongly on Earth and on the water on the far side of Earth, which results in tides. What causes tides? • Tides are the rise and fall of ocean water.

Doe (White Rock, B.C., Canada) 1. Introduction. Captain George Vancouver's survey of the North Pacific coast of America has been characterized as being among the most distinguished work of its kind ever done. For three summers, he and his men worked from dawn to dusk, exploring the many inlets of the coastal mountains, any one of which, according to the theoretical geographers of the time, might have provided a long-sought-for passage to the Atlantic Ocean. Vancouver returned to England in poor health,1 but with the help of his brother John, he managed to complete his charts and most of the book describing his voyage before he died in 1798.2 He was not popular with the British Establishment, and after his death, all of his notes and personal papers were lost, as were the logs and journals of several of his officers. Vancouver's voyage came at an interesting time of transition in the technology for determining longitude at sea.3 Even though he had died sixteen years earlier, John Harrison's long struggle to convince the Board of Longitude that marine chronometers were the answer was not quite over.

  • BOAT CREW HANDBOOK – Boat Operations
    BOAT CREW HANDBOOK – Boat Operations Sumner I. Kimball, USLSS BCH16114.1 December 2017 Sumner Increase Kimball, USLSS A young lawyer from Maine, Sumner I. Kimball was appointed as the chief of the Treasury Department's Revenue Marine Division in 1871. He had joined the Treasury Department as a clerk 10 years earlier and had proven his abilities as a manager. Using his hard-earned political know-how, and a good dose of Yankee common sense, Kimball proceeded to completely overhaul the Revenue Marine and the hodge-podge system of lifesaving stations along the nation's coast that were also under the control of the Revenue Marine Division. His impact on both organizations would prove to be immeasurable. After the Civil War, the Revenue Marine, and the executive branch agencies generally, came under intense Congressional scrutiny. Economy was the name of the game during this time and expenditures were scrutinized across the board. Hence, Kimball decided to order the construction of new cutters not with iron hulls, which entailed considerable expense, but with proven wood hulls. The total number of petty officers and enlisted men was substantially cut and their pay reduced. Kimball also carried out a vigorous "housecleaning" of incompetent Revenue Marine officers and saw to it that discipline was tightened. A special object of his censure was the use of cutters as personal yachts by local Custom officials, a wide-spread abuse during that time. Kimball also put into effect a merit system to determine promotions. He also made one other great contribution to the quality of the Revenue Marine by establishing, in 1877, a School of Instruction, to train young officers.

  • Direction In
    What is meant by Direction ? Direction is the information contained in the relative position of one point with respect to another point without the distance information. Directions may be either relative to some indicated reference, or absolute . Direction is often indicated manually by an extended index finger or written as an arrow. On a vertically oriented sign representing a horizontal plane, such as a road sign, "forward" is usually indicated by an upward arrow. ASKING FOR ? DIRECTIONS How do I get to...? How can I get to...?
