Planetary Post March 2017 ISSUE # 118 Planetary Post March 2017 As is known, March is a “light” month since BRAS’ annual star party draws ASTRONEWS personnel away from HRPO for a week. Patrons will hardly notice—the first attempt of the year to view the most elusive planet, Mercury, is this month; Dr. Michoud Assembly Facility Struck Juhan Frank gives an outline of star birth and death to prepare the public for by Tornado <> Uranus Distances the upcoming presentation of information about Tabby’s Star; our latest twilight Itself from Zeta Piscium <> Jupiter viewing session is scheduled; and Dr. Juana Moreno and her students return Enters Evening Sky <> with their annual nanotechnology event, suitable for most ages of the family. Penumbral Lunar Eclipse Views One more surprise—the Skygazing Tip section will return in April with all new Hindered by Clouds <> general suggestions and a suggested object to view! Attendance for HRPO Solar Viewing Doubles in 2017 <> Geomagnetic Storm Activity Calendar of events Predicted for Early March <> 30th Anniversary of Supernova 1987A Discovery <> TRAPPIST­1 has HRPO will be closed on 22, 23 and 24 March for the Hodges Gardens Multiple Planets Orbiting Star Party. FRIDAY NIGHT LECTURE SERIES No admission fee. For ages fourteen and older. Fridays at 7:30pm 3 March: “Stellar Evolution” A star’s life is very dependent on its initial mass. The unaided­eye stars that we see nightly are at different stages in their development. Some are young and blue, some middle­aged and yellow, some elderly and red. LSU physics professor Juhan Frank will condense the lives of stars to one hour! 20/20 VISION CAMPAIGN 17 March: “Mercury and Venus” One zips around the Sun in eighty­eight Earth days and one has a hellish atmosphere of temperature and pressure. From our vantage point, each can go through phases! Why are Mercury and GLOBE at Night Venus so different? Can we view these planets from our homes? Measurements: 20 to 29 March. 31 March: “NASA Spinoff Technology” HRPO Center Supervisor Tom Northrop gives the audience an overview of the fascinating objects and technology that developed as a direct result of the American Space Program.

For all ages. Binoculars recommended. It’s not light, it’s not dark. It’s that special time called twilight, and HRPO wants to introduce you to it! Are all sections of the sky the same shade of blue? Which stars are seen first? Are Mercury and Venus or the Moon out? Is that moving object a plane, a satellite or space debris? How much actual darkness should I expect in a light­polluted city when twilight has passed? There is no other time like twilight. Bring it into your life! NOTE: This program pre­empts the Friday Night Lecture Series on the last Friday in March before Daylight Time begins, and on the first Friday in November after Daylight Time ends. LIGHT POLLUTION COMMITTEE MEETING Monday 13 March from 6:15pm to 7pm No admission fee. For ages fourteen and older. Are you a local skygazer, homeowner, business owner, science teacher or stakeholder interested reclaiming a natural sky above HRPO and its surrounding while simultaneously saving money and energy, and making driving safer? Please join us for this monthly discussion; no RSVP is necessary! BATON ROUGE ASTRONOMICAL SOCIETY MEETING Monday 13 March from 7pm to 9pm No admission fee. For ages fourteen and older. Speakers and Topics: various For over thirty years BRAS has educated countless numbers of citizens in the joys of planetary and deep­sky gazing, and factors to consider when buying a pair of binoculars or a telescope. BRAS members have published in Astronomy, Sky & Telescope and Scientific American. BRAS members have constructed their own telescopes and photographic platforms. BRAS members have entered robotics competitions, imaged comets, earned observing certificates and discovered asteroids. BRAS members have been interviewed by local media and the National Geographic Society. Anyone interested in learning more about BRAS is invited to attend. PLANET TIME: MERCURY Saturday, 18 March from 3:45pm to 5:45pm (first attempt) No admission fee. For all ages. Weather permitting, viewing of Mercury☿ through one or more telescopes will take place. During this time the planet will be in a gibbous phase, shining at magnitude ­1.3 with a maximum altitude of 53°. Please keep headlights off while parking and leaving, and drive slowly! NOTE: The second of these viewing attempts will take place on 1 July. NANODAYS Saturday 25 March from 2pm to 6pm / No admission fee. For ages six and older. For the eighth consecutive year at HRPO, big things in the Universe take a backseat to all things tiny. Children and adults alike will­­­ ­­­be able to see how big they are compared to nanoscale objects. ­­­understand how a Scanning Probe Microscope explores the nanoworld. ­­­try to pour water out of a nano­cup. ­­­learn about nanomaterials use in constructing stain­free clothes. ­­­have a chance to build models of nanoscale structures. ­­­play with liquid crystals. ­­­make fluids part in the middle by applying magnets to them. Solar viewing will take place from 2pm to 4pm, and lunar viewing from 4:30pm to 6pm! 11TH ANNUAL INTERNATIONAL ASTRONOMY DAY Saturday 29 April from 3pm to 11pm / No admission fee. For all ages. It’s back—the greatest IAD event in the area returns for its tenth anniversary. Once again, HRPO will host visitors from the Baton Rouge Amateur Radio Club, the Baton Rouge Gem and Mineral Society, the Baton Rouge Metropolitan Airport, the Bluebonnet Swamp Nature Center, the Civil Air Patrol, the East Baton Rouge Parish Library and LIGO. A Scope­on­a­Rope session and a chemistry demonstration will also take place. There will be viewing (weather permitting) of the Sun, the Moon, Mars, Jupiter, Saturn and Omega Centauri. Also, this will be the fourth year that the IAD event will host multiple robots from local U.S. First Robotics high school teams! There will be a dry slide and spacewalk for the kids, as well as a bonus ride. The hugely popular Adventure Quest game will return. Delicious food and drink from Louisiana Lemonade and City Gelato and others will fill your stomach. There will be raffle drawings for prizes totaling over $600. Mark your calendar and don’t miss it!

The nights are starting earlier and earlier as the weather becomes more and more comfortable and all of our old favorites of the fall and winter skies really start finding their places right where they belong. October was a busy month for us, with several big functions at the Observatory, including two oppositions and two more all night celebrations. By comparison, November is looking fairly calm, the big focus there is going to be our third annual Natural Sky Conference on the 13th, which I’m encouraging people who care about the state of light pollution in our city and the surrounding area to get involved in.

  • Jupiter Calendar
    Principle of Jupiter calendar “A further refinement of the calendar was the introduction into dating of the place of a year according to its position in relation to the orbital revolution of the planet Jupiter, called brhaspati in Sanskrit. Jupiter has a sidereal period (its movement with respect to the “fixed” stars) of 11 years, 314 days, and 839 minutes, so in nearly 12 years it is back into conjunction with those stars from which it began its orbit. Its synodic period brings it into conjunction with the Sun every 398 days and 88 minutes, a little more than a year. Thus, Jupiter in a period of almost 12 years passes about the same series of nakshatras that the Sun passes in one year and, in a year, about the same nakshatras as the Sun in a month. A year then can be dated as the month of a 12-year cycle of Jupiter, and the date is given as, for example, grand month of Caitra. This is extended to a unit of five cycles, or the 60-year cycle of Jupiter (brhaspaticakra), and a “century” of 60 years is formed. This system is known from the 6th century AD onward.” From: "calendar." Encyclopædia Britannica. Encyclopædia Britannica 2009 Ultimate Reference Suite. Chicago: Encyclopædia Britannica, 2009. The 60-years cycle mentioned in the excerpt from “Britannica” was used to measure the precession’s rate. The following table shows the advance of the tropical Jupiter calendar with respect to the sidereal Jupiter calendar. This advance is a measurement of the precession’s rate.
