COLE 153 Preface Preface This year, we start our second quarter century. Unlike a 25th anniversary being “silver,” we couldn’t find one for 26 years. So, we’ll take the liberty of calling this the “Silicon Anniversary” for the Society. Why Sili- con? Because so much of the work being done by amateurs and professionals relies on CCD cameras and com- puters, where silicon is the prime ingredient in the chips in both that make them do their magic. We have, indeed, entered a “golden” era for astronomy. Not for many years has amateur involvement been so critical to the advancement of at least this branch of science. Amateurs have capable resources and, most important, the time and flexibility of schedule that allows them observing opportunities not always available to professionals. Of course, on the other side of the coin, professionals have access to much more sophisticated equipment that can go fainter, deeper, and finer. The two groups working together are a very powerful force in unlocking the secrets of the Universe. The Symposium on Telescope Science, originally under the direction of the IAPPP and since 2003 by the Society for Astronomical Sciences, has been held in Southern California since 1982 but not always in its current location of Big Bear Lake, California. The timing and location of the meeting are not by chance. The Sympo- sium is meant to be a lead-in to one of the biggest star parties and astronomical swap meets in the world, the annual RTMC Astronomy Expo, held just a few miles from Big Bear on the weekend following the Sympo- sium. Through the three days of the Symposium on Telescope Science, the Society hopes to foster new friend- ships and new collaborations among amateur and professional astronomers. Our goals are the personal scientific advancement of Society members, the development of the amateur-professional community, and promoting research that increases our understanding of the Universe. It takes many people to have a successful conference, starting with the Conference Committee. This year the committee members are: Lee Snyder Robert Stephens Robert Gill Dave Kenyon Dale Mais Brian D. Warner Jerry Foote There are many others involved in a successful conference. The editors take time to note the many volun- teers who put in considerable time and resources. We also thank the staff and management of the Northwoods Resort in Big Bear Lake, CA, for their efforts at accommodating the Society and our activities. Membership dues alone do not cover the costs of the Society and annual conference. We owe a great debt of gratitude to our corporate sponsors: Sky and Telescope, Software Bisque, Santa Barbara Instruments Group, and Apogee Instruments, Inc. Finally, there would be no conference without our speakers and poster presenters. We thank them for mak- ing the time to prepare and present the results of their research. Brian D.

Over a 50-year ca- reer, he collected hundreds of thousands of photoelectric observations. This paper describes an ambitious pro- ject started by the AAVSO to digitize his observational archive. 1.

He worked with many of the notable astronomers over the last half of the 20th century, including Sandage, Lynden-Bell, Greenstein, Herbig and others. He was well known as a careful researcher, never observing unless it was perfectly clear, and always substantiating any claim he made in a paper. However, Eggen was not without contro- versy, having a gruff personality, always willing to voice his opinion on a topic, even resigning his membership in the IAU around 1970. We will leave his most famous episode, “the Neptune file,” for other historians to comment about! 2. Eggen's Legacy Eggen was well known as a proponent of small- telescope science. However, what the AAVSO is most interested in is that Eggen published only a small part of the enormous amount of data he col- Figure 1.

  • Early Observations of the Interstellar Comet 2I/Borisov
    geosciences Article Early Observations of the Interstellar Comet 2I/Borisov Chien-Hsiu Lee NSF’s National Optical-Infrared Astronomy Research Laboratory, Tucson, AZ 85719, USA; [email protected]; Tel.: +1-520-318-8368 Received: 26 November 2019; Accepted: 11 December 2019; Published: 17 December 2019 Abstract: 2I/Borisov is the second ever interstellar object (ISO). It is very different from the first ISO ’Oumuamua by showing cometary activities, and hence provides a unique opportunity to study comets that are formed around other stars. Here we present early imaging and spectroscopic follow-ups to study its properties, which reveal an (up to) 5.9 km comet with an extended coma and a short tail. Our spectroscopic data do not reveal any emission lines between 4000–9000 Angstrom; nevertheless, we are able to put an upper limit on the flux of the C2 emission line, suggesting modest cometary activities at early epochs. These properties are similar to comets in the solar system, and suggest that 2I/Borisov—while from another star—is not too different from its solar siblings. Keywords: comets: general; comets: individual (2I/Borisov); solar system: formation 1. Introduction 2I/Borisov was first seen by Gennady Borisov on 30 August 2019. As more observations were conducted in the next few days, there was growing evidence that this might be an interstellar object (ISO), especially its large orbital eccentricity. However, the first astrometric measurements do not have enough timespan and are not of same quality, hence the high eccentricity is yet to be confirmed. This had all changed by 11 September; where more than 100 astrometric measurements over 12 days, Ref [1] pinned down the orbit elements of 2I/Borisov, with an eccentricity of 3.15 ± 0.13, hence confirming the interstellar nature.

The near- 454 MATHESIS, 477 ITALIA, AND 2264 SABRINA perfect overlay of V- and R-band data show no evidence of color change as the asteroid rotates. This result replicates the lightcurve Robert K. Buchheim period reported by Harris et al. (1984), and matches the period and Altimira Observatory lightcurve shape reported by Behrend (2005) at his website. 18 Altimira, Coto de Caza, CA 92679 USA [email protected] (Received: 4 November Revised: 21 November) Photometric studies of asteroids 133 Cyrene, 454 Mathesis, 477 Italia and 2264 Sabrina are reported. The lightcurve period for Cyrene of 12.707±0.015 h (with amplitude 0.22 mag) confirms prior studies. The lightcurve period of 8.37784±0.00003 h (amplitude 0.32 mag) for Mathesis differs from previous studies. For Italia, color indices (B-V)=0.87±0.07, (V-R)=0.48±0.05, and phase curve parameters H=10.4, G=0.15 have been determined. For Sabrina, this study provides the first reported lightcurve period 43.41±0.02 h, with 0.30 mag amplitude. Altimira Observatory, located in southern California, is equipped with a 0.28-m Schmidt-Cassegrain telescope (Celestron NexStar- 454 Mathesis. DiMartino et al. (1994) reported a rotation period of 11 operating at F/6.3), and CCD imager (ST-8XE NABG, with 7.075 h with amplitude 0.28 mag for this asteroid, based on two Johnson-Cousins filters).

On leaving the planetarium, turn around and look northwards over the roof of the building. To your right is a group of stars like the outline of a saucepan standing up on it’s handle. This is the Plough (also called the Big Dipper) and is part of the constellation Ursa Major, the Great Bear. The top two stars are called the Pointers. Check with binoculars. Not all stars are white. The colour shows that Dubhe is cooler than Merak in the same way that red-hot is cooler than white-hot. 2. Use the Pointers to guide you to the left, to the next bright star. This is Polaris, the Pole (or North) Star. Note that it is not the brightest star in the sky, a common misconception. Below and to the right are two prominent but fainter stars. These are Kochab and Pherkad, the Guardians of the Pole. Look carefully and you will notice that Kochab is slightly orange when compared to Polaris.

It consists of a humorous 24-minute show and educator’s package. The Orion Educator’s Guide is designed for Planetarians, Teachers, and parents. The information is researched, organized, and laid out so that the educator need not spend hours coming up with lesson plans or labs. This has already been accomplished by certified educators. The guide is written to alleviate the fear of space and the night sky (that many elementary and middle school teachers have) when it comes to that section of the science lesson plan. It is an excellent tool that allows the parents to be a part of the learning experience. The guide is devised in such a way that there are plenty of visuals to assist the educator and student in finding the Winter constellations.
