It can be found in the centre of the Winter Triangle of Betelgeuse, Procyon and Sirius. Monoceros is a relatively modern constellation. Its first certain appearance was on a globe created by the Dutch cartographer Petrus Plancius in 1612. Notable stars: Monocerotis – Beautiful triple star mags 4.7, 5.2 and 6.1 Mon – A lovely double mags 4.4 and 6.6, separation 12” V838 – Variable star that suddenly increased its brightness by a factor of 10,000 on 6th Jan 3002. The light echo was followed using the HST. Image Credit: Torsten Bronger Some Interesting Objects: M50 NGC 2323. Open cluster mag. 5.9. NGC 2264 The Christmas tree cluster, Cone nebula, Foxfur nebula region. NGC 2261 C46. Hubble’s variable nebula, mag 9-10. Changes due to movement of dust clouds. NGC 2238 The rosette nebula region, including the cluster NGC 2244 (C50). The Milky Way goes through Monoceros and the region contains many interesting dust and gas clouds, nebulae and star clusters. Lunar Feature of the Month Maurolycus The southern highland region of the moon can be a confusing tangle of thousands of craters, big and small, but one particular crater than stands out in this area, for me at least and excluding Clavius, is the crater Maurolycus. When you observe this crater its quite apparent that Maurolycus is overlapped by other ancient cra- ters which makes for a observing delight. The crater itself is approximately 4.7 km deep and has high terraced walls which make for fascinating viewing during sunrise and sunset over the crater. Maurolycus, just below centre, by David Scanlan, FRAS The Sun in February The Sun has shown continuing activity during February, particularly in the southern hemisphere, leading to the prospect of an approaching maximum. Of special interest this month is sunspot 1944, shown here on January 7, when it produced an earth-bound X class flare. It then went behind the western limb, only to re- turn again on January 28, when it was re-designated AR1967. It disappeared again around the western limb on February13. On February 24, most solar activity was coming from a location hidden behind the Sun's south-eastern limb (circled area). It is likely that this is sunspot AR1967, returning from a two-week transit across the far side of the Sun. The place to watch is circled. If this is AR1967, it will mark the third time the active region has crossed the visible face of the sun. Sun- spots seldom last more than two or three weeks; two or three months is remarkable. By now the returning spot is unlikely to be as powerful as previous passes. However, flares and CMEs appearing over the south- eastern limb hint at some remaining potency.

Public Star Party Follows at the It’s that time of year when obstacles appear in the sky. In particular, this year is Centennial Obs. loaded with fog. It got in the way of letting us see the dance of the Jovian moons late last month, and it’s hindered our views of other unique shows. Still, members Club Officers reported finding enough of a clear sky to let us see Comet Lovejoy, and some great photos by members are popping up on the Facebook page. Robert Mayer, President This month, however, is a great opportunity to see the benefit of something [email protected] getting in the way. Our own Chris Anderson of the Herrett Center has been using 208-312-1203 the Centennial Observatory’s scope to do work on occultation’s, particularly with asteroids. This month’s MVAS meeting on Feb. 14th will give him the stage to Terry Wofford, Vice President show us just how this all works. [email protected] The following weekend may also be the time the weather allows us to resume 208-308-1821 MVAS-only star parties. Feb. 21 is a great window for a possible star party; we’ll announce the location if the weather permits. However, if we don’t get that Gary Leavitt, Secretary window, we’ll fall back on what has become a MVAS tradition: Planetarium night [email protected] at the Herrett Center.
  • A Basic Requirement for Studying the Heavens Is Determining Where In

    A Basic Requirement for Studying the Heavens Is Determining Where In

    Abasic requirement for studying the heavens is determining where in the sky things are. To specify sky positions, astronomers have developed several coordinate systems. Each uses a coordinate grid projected on to the celestial sphere, in analogy to the geographic coordinate system used on the surface of the Earth. The coordinate systems differ only in their choice of the fundamental plane, which divides the sky into two equal hemispheres along a great circle (the fundamental plane of the geographic system is the Earth's equator) . Each coordinate system is named for its choice of fundamental plane. The equatorial coordinate system is probably the most widely used celestial coordinate system. It is also the one most closely related to the geographic coordinate system, because they use the same fun­ damental plane and the same poles. The projection of the Earth's equator onto the celestial sphere is called the celestial equator. Similarly, projecting the geographic poles on to the celest ial sphere defines the north and south celestial poles. However, there is an important difference between the equatorial and geographic coordinate systems: the geographic system is fixed to the Earth; it rotates as the Earth does . The equatorial system is fixed to the stars, so it appears to rotate across the sky with the stars, but of course it's really the Earth rotating under the fixed sky. The latitudinal (latitude-like) angle of the equatorial system is called declination (Dec for short) . It measures the angle of an object above or below the celestial equator. The longitud inal angle is called the right ascension (RA for short).

This book can be referenced as follows: Reipurth, B. 2016, http://ifa.hawaii.edu/SP1 i FOREWORD I first learned about George Herbig’s work when I was a teenager. I grew up in Denmark in the 1950s, a time when Europe was healing the wounds after the ravages of the Second World War. Already at the age of 7 I had fallen in love with astronomy, but information was very hard to come by in those days, so I scraped together what I could, mainly relying on the local library. At some point I was introduced to the magazine Sky and Telescope, and soon invested my pocket money in a subscription. Every month I would sit at our dining room table with a dictionary and work my way through the latest issue. In one issue I read about Herbig-Haro objects, and I was completely mesmerized that these objects could be signposts of the formation of stars, and I dreamt about some day being able to contribute to this field of study.
  • SAA 100 Club

    SAA 100 Club

    S.A.A. 100 Observing Club Raleigh Astronomy Club Version 1.2 07-AUG-2005 Introduction Welcome to the S.A.A. 100 Observing Club! This list started on the USENET newsgroup sci.astro.amateur when someone asked about everyone’s favorite, non-Messier objects for medium sized telescopes (8-12”). The members of the group nominated objects and voted for their favorites. The top 100 objects, by number of votes, were collected and ranked into a list that was published. This list is a good next step for someone who has observed all the objects on the Messier list. Since it includes objects in both the Northern and Southern Hemispheres (DEC +72 to -72), the award has two different levels to accommodate those observers who aren't able to travel. The first level, the Silver SAA 100 award requires 88 objects (all visible from North Carolina). The Gold SAA 100 Award requires all 100 objects to be observed. One further note, many of these objects are on other observing lists, especially Patrick Moore's Caldwell list. For convenience, there is a table mapping various SAA100 objects with their Caldwell counterparts. This will facilitate observers who are working or have worked on these lists of objects. We hope you enjoy looking at all the great objects recommended by other avid astronomers! Rules In order to earn the Silver certificate for the program, the applicant must meet the following qualifications: 1. Be a member in good standing of the Raleigh Astronomy Club. 2. Observe 80 Silver observations. 3. Record the time and date of each observation.

Next Meeting: March 26th Prelude to a Night of Observing by Sam Pitts and Jerry Oltion At our March meeting Sam Pitts will talk about the things a person should consider when getting ready for a night’s observing. He’ll also cover how to find what you’re looking for in the sky, and since March is the Messier month (when all 110 Messier objects are visible to dedicated all-nighters) he’ll discuss the best strategy for observing those as well. Since Jerry couldn’t make it to the February meeting, he will do his collimation and mirror cleaning demonstrations at the March meeting. We’ll also have a “What’s up” program on what else besides the Messier objects are visible in the March sky, and Jacob Strandlien will present the news in astronomy covering the last few months. And as always, we encourage the sharing of astronomy-related questions, news, or projects with other members of the club. Next First Quarter Friday: March 6th Our next First Quarter Friday star party will be March 6th. Bring your scope to the College Hill Reservoir (24th and Lawrence in Eugene) and share the view with whoever shows up. Here are the dates through December of 2009.
