Most current schedules run out in December but clubs commonly can not set up next year's events. Their hosts are on holiday or are short-staffed until January. If your anticipated event is in the '???' or 'SPR' section, please ask at the contact for latest news. Recall that many events were killed by summer and autumn floods and winds. Winter weather, with cold and ice, can continue this interdiction. Inquire at event contact for last-minute cancellations and be aware of adverse road/rail conditions. I moved Vasssar and Wesleyan observatory public nights to the 'SPR' section. Both colleges enter their winter breaks and intersessions during December and into January, The could be a last session in early December which you may inquire after at the contact. Instt Study Anct Wld has lectures at various hours, as it did in November 2018. The caution note against each lecture in the November NYC Events confused some readers, I omitted these nots to let you treat each entry for its hour. This year's Holiday Train has a new route, no longer doing local stops in 6th Av and turning at Queens Pz. it's an express, like route D trains, turning at 125 St/8 Av. Riders on the early runs after Thanksgiving report that the train may continue one more stop to 145 St/StN to berth in its center track. See under Dec 2nd. Several event contacts were updated. Most were furnished by clubs taking part in the NYSkies Observer's Handbook offer. With the fever about bright comet wirtamen, astronomy centers may add extra starviewings for it. These may be set up on short notice. Inquire at your local astronomy center for latest news. City news ------- I got several good comments for my new piece on Einstein's equation. Most noted the wording in the 'spin-off features' was klunky. I revisited this section and made minor changes elsewhere. The upgraded article is at www.nyskies.org/articles/pazmino/emc2.htm Some remote readers voiced vivid interest to apply E=mc2 to a local factory or industry that derives energy. from heat. The Observer's Handbook offer is still alive. Barely. We are receiving a steady flow of requests, running down our stock. If you or your club has pending need for the OH, your request just MUST get to NYSkies TODAY. What happens if we run out when we get your request? No problem. We return your unbanked check with the stomach-churning 'SORRY!' letter. You know soonest you see the envelope in your letter box. It's a flat business-size one, not the hefty thick one with the book inside. NYSkies Astronomy Seminar on 2 November 2018 studied several kinds of trajectory for spaceflight. We learned that serious discussion about flying to other planets began in the 19-ohs. Hohmann worked out the minimum-energy flightpath between planets during WWI but held it secret for fear of military use. He published his calculations in 1925. We saw that a Hohmann path is an ellipse tangent to the home and target planet orbits. The spacecraft leaves the home planet such it arrives at the other end of the ellipse when the target planet also arrives there. The only fuel needed is to adjust the speed of the craft to match the planet's. In 1928 vanPirquet proposed a compromise path lasting 2/3 the Hohmann path but needs speed adjustment radially from the Sun.The realization of interplanetary flight came in the 1960s when USSR and US were fielding probes to Venus, Moon, Mars. These followed Hohmann or vanPirquet trajectories.To reach the farther planets NASA developed the gravity assist method of modifying a craft's speed and direction by passing near an intermediate planet. The planet's gravity diverts the craft toward its target. According as the flight plan the bypass may either increase or decrease the probe's speed. For the Pioneer and Voyager flights the flyby of planets for gravity assist was also a chance to examine the orbs. Gravity assist is used for the exploration of Jupiter and farther planets. We learned that gravity assist is used for shifting the orbit plane of the probe, like for Ulysses and Juno. The former was put into a polar orbit around the Sun via Jupiter. Juno was shifted into a polar orbit around Jupiter. We examined the use of Lagrange points in the Earth-sun and Earth-Moon systems. These are places around the two bodies where a probe can coorbit with the Moon or Earth. In nature two points, L4 and L5 in the Jupiter-sun system are abodes of the Trojan asteroids. These pace Jupiter in his orbit, staying 60 degrees ahead and behind him. Points L1 and L2 are used to station Earth-orbiting probes to maintain the same position relative to Sun or Moon. Genesis and SOHO were sent to L1, 1.5 million kilometers toward the Sun. WMAP Planck, and Herschel were at L2,, 1.5 million kilometers opposite from the Sun. The Lagrange points behave like virtual gravity centers, allowing probes to do small orbits around them, sometimes called a 'halo orbt'. The Trrojan asteroids orbit around their L4/L5 centers. Takeaways were diagrams of many spacecraft trajectoris,historical pictures of early spaceflight articles, path of Dawn via Hohmann and ion-engine propulsion, Hohmann round-trip flight to mars, gravity assist vector triangle diagram, lunar assist to speed a probe but resist to slow the rocket for return to Earth, graphical explanation of Lagrange L1 and L2 points. on 16 November 2018 Intl Comte on Wts and Mwasrs set fixed permanent values for several physical constants and redefined the kilogram. Constants, previously measured quantities, now have exact values no longer experimentally determined. The kilogram is defined from Planck constant, with its new fixed value, as (mass) = (Planck) * (frequency) / ((lightspeed) ^ 2). New constants are ------------------------------------ Planck = 6.62607015e-24 kg.m2/s ('big-h'= 2*pi*'small-h') electron charge = 1.602176634e-19 A.s (A.s is the Coulomb) Avogadro = 6.02214076e23 atom/mole (gram mass = atomic mass) water triple point = 273.16 K (liq-sol-vap interface) Boltzmann = 1.3801649e-23 kg.m2/K.s2 --------------------------------------------------------------- Other units derived from these constants are jiggered into new values. New scheme takes effect on 20 May 2019. Until then the kilogram is the mass of actual metal plug in care of Comte in France. - The New York Wheel project was cancelled on 23 October 2018. it proposed a 192m tall Ferris wheel facing manhattan on Staten Is north shore.Ride would be one revolution per two hours, some with light snacks in the cabin. Finances ran out and concern increased about toppling in storms. project featured shopping and commuter parking, which continue building. NYSkies Astronomy Seminar on Friday 16 November 2018 showed how Einstein's E=mc2 applies to our daily life. We also learned how heat behaves in producing energy. The dialog centered on my new piece on the Einstein formula, supplemented by pictures of electric utility equipment. We recalled that humans extract useful work from both heat and other prime sources of energy. Water mills, chemical batteries, helioelectric cells are examples of nonthermal energy. For humans there is so far only one source of continuous, economical, reliable, abundant energy, that from heat. machines extract energy from a high temperature, produced by combustion of fuel, and reject some heat at a lower temperature. We learned that when steam machines were new in the late 1700s it was assumed they threw away heat because of mechanical losses. In time far more input heat would go into work. Carnot in early 1800s found there is a maximum limit for extracting work from heat, based on the high and low temperatures. No machine running between these temperatures can get a greater work output than the Carnot limit. We learned that all energy, hear or otherwise, comes from conversion of mass into that energy. The amount of converted mass in ordinary life is so tiny it is usually undetectable. The rule was that mass is constant in a given situation with no gain or loss. Energy was treated as a content of the mass that is released by suitable process. We took a close look at statistics from Con Edison's generating stations, from data collected for previous astronomy discussions in the 1980s. The company spent, in 1987, over $600 million for petroleum, natural methane, and uranium. Of the heat released in the power plants, only about 36% got into electric. The rest was discharged into the surrounds as waste energy. This annoyingly large amount is mostly due to the Carnot limit between the temperature of steam leaving the boiler and condensed steam returning to the boiler. We then inquired for the mass equivalent of the electric, finding it to be barely one kilogram. It took a few seconds for the fact to absorb, but if there was some device that turns mass completely into energy, one kilo could yield all the electric produced by immense quantities of oil, gas, and uranium. and almost all, but for a kilo, were hauled or exhausted away as sludge, smoke, soot. We compared Con Edison's efficiency of energy with that from a typical nuclear power plant. We studied the uranium fission process and figured that it yielded a seemingly small amount of energy. Scaling the amount from a single uranium nucleus to a full kilo, the fission energy is an incredible TWO MILLION times more than from combustion of coal. We then looked at the main example studied by home astronomers, the hydrogen-helium process of the Sun. We reviewed the interaction of protons and helium nuclei and some alternative names for subatomic particles. The energy from a single H->he is small but in aggregate it delivers the observed total energy output of the Sun. The ratio of total solar output to single reaction output yields a mass loss of some 4 million tons peer second. We noted that this was until this year an undetectable amount based on the astrometry of planet orbits. In spring 2018 analysis of astrometry of Mercury from the MESSENGER probe showed that Mercury's orbit is enlarging from the Sun's declining gravity, answering to losing mass of 4 million tons per second.. We followed up with figuring out the lifetime of the Sun by dividing the total hydrogen mass loss by the loss per second, finding a life of some 8.2 billion years. The caution is that this method works only for Main Sequence stars, not any star away from the MS, because it is based on the H->He energy process.. We wrapped up by estimating the lifetime of other MS stars by proportion from the Sun. Sirius has twice the total mass loss as the Sun and 25 times faster mass loss. its lifetime is about 650 million years. The rest of the meeting was spent studying pictures of electric power plant equipment, such as Con Edison power plants, coal and nuclear boilers, hyperbolic towers, turbines, transmission lines, subsations. Some of us never knew that the walled-in lot they pass by is a Con Edison substation. Takeaways were diagrams of heat cycles, Carnot limit, uranium fission chain reaction, proton-proton solar energy CYcle, power plant water- steam flow, historical Con Edison stations, assorted interior views of facilities. NYC Transit cautions that for balanced running some N and M trains are sent uptown into 2nd Av line. N normally works Astoria line; M, Queens Bv. Be sure of train route before boarding. On 2018 Nov 15 Lund University reported on a missing piece of the Antikythera Machine. Undersea archaeologists exploring the original ship wreck off of Antikythera island in 2017 found a 6-7 cm diameter bronze disc that could be part of the machine. it has cogs, four pointer arms, and an engraved picture of Taurus. It seems to fit into a broken section of the mechanism. Amazon Inc on 13 november 2018 announced it will build its East Coast HQ in both Long island City QN and Crystal City VA. The LIC site is near Queensbridge houses and Ravenswood power plant, with four subway stations, ferry station, and LIRR. Amazon also takes space in Citicorp Annex, moving a thousand employees into it during 2019. Most of site is occupied by city agencies, wo will relocate else where. Amazon will build new 800,000m2 campus by 2023. Sky news ------ The first round of Globe at Night was mixed with many cloudy nights and a few clear ones. The next round is November 29 thru December 8. The essential failure of many readers to obtain good readings is the lack of night vision. You MUST get some night vision before inspecting Orion. Stay in a shaded spot or dark room for a couple minutes and then do the sky assessment. Else you'll record abysmal values. As at 27 Nov 2018 there were no sightings of Milky Way from within the City. Even the clear nights were too hazy for MW, but allowed for other good observing. Season ends November 30th, next spring's season opens on May 1st. Geminid meteors fall in mid December during pass of comet Wirtamen and, uh, large Moon. In this century the Geminids generally grew to equal the activity of the Perseids. Geminids, altho occurring in winter, are observable from late night rather than only from owl hours. First major snowfall of 2018-19 fell in NYSkies on 2018 November 14. On Manhattan granular snow began ~13h EST, then fully formed flakes by 15h. Cover reached 13-15cm in Central Pk by sunset. Rain mixed with snow at nightfall, becoming all rain in late night. N & W NYSkies sectors got 20-25cm cover; LI, 5-8cm. 22018 November 22 was City's 2nd coldest Thanksgiving Day at -6C under sunny windy sky. Parade balloons were held close to ground to avoid buffeting by wind. Day tied previous coldest Thanksgiving in 1901, also at -6C, The 2018 day had City's coldest PARADE because the parades didn't begin until 1924. With the longer nights of winter and earlier nightfall, do keep an eye for aurorae. While solar activity is low and City is far from magnetic pole, we do get northern lights. For background see www.nyskies.org/articles/pazmino/arourany.htm Intl Earth Rotation Svc reminds that there is NO loeapsecond added at end of December 2018. The final minute of year has normal 60 seconds. The offset (UTC - RAI) remains -37 seconds until further notice.
