The Midnight Sky: Familiar Notes on the Stars and Planets, Edward Durkin, July 15, 1869 a Good Way to Start – Find North
The expression "dog days" refers to the period from July 3 through Aug. 11 when our brightest night star, SIRIUS (aka the dog star), rises in conjunction* with the sun. Conjunction, in astronomy, is defined as the apparent meeting or passing of two celestial bodies. TAAS Fabulous Fifty A program for those new to astronomy Friday Evening, July 20, 2018, 8:00 pm All TAAS and other new and not so new astronomers are welcome. What is the TAAS Fabulous 50 Program? It is a set of 4 meetings spread across a calendar year in which a beginner to astronomy learns to locate 50 of the most prominent night sky objects visible to the naked eye. These include stars, constellations, asterisms, and Messier objects. Methodology 1. Meeting dates for each season in year 2018 Winter Jan 19 Spring Apr 20 Summer Jul 20 Fall Oct 19 2.

Popular Names of Deep Sky (Galaxies,Nebulae and Clusters) Viciana’S List
POPULAR NAMES OF DEEP SKY (GALAXIES,NEBULAE AND CLUSTERS) VICIANA’S LIST 2ª version August 2014 There isn’t any astronomical guide or star chart without a list of popular names of deep sky objects. Given the huge amount of celestial bodies labeled only with a number, the popular names given to them serve as a friendly anchor in a broad and complicated science such as Astronomy The origin of these names is varied. Some of them come from mythology (Pleiades); others from their discoverer; some describe their shape or singularities; (for instance, a rotten egg, because of its odor); and others belong to a constellation (Great Orion Nebula); etc. The real popular names of celestial bodies are those that for some special characteristic, have been inspired by the imagination of astronomers and amateurs. The most complete list is proposed by SEDS (Students for the Exploration and Development of Space). Other sources that have been used to produce this illustrated dictionary are AstroSurf, Wikipedia, Astronomy Picture of the Day, Skymap computer program, Cartes du ciel and a large bibliography of THE NAMES OF THE UNIVERSE. If you know other name of popular deep sky objects and you think it is important to include them in the popular names’ list, please send it to [email protected] with at least three references from different websites. If you have a good photo of some of the deep sky objects, please send it with standard technical specifications and an optional comment. It will be published in the names of the Universe blog. It could also be included in the ILLUSTRATED DICTIONARY OF POPULAR NAMES OF DEEP SKY. -

The Planetary Nebula Club Objects by Month (As Posted by Ted Forte On
The Planetary Nebula Club objects by month (As posted by Ted Forte on “backbayastro”) August Planetaries As most of you know, I am the coordinator of the Astronomical League’s Planetary Nebula Club. Several members of the BBAA helped me create the Planetary Nebula Club by serving on the object selection committee, serving on the rules committee, providing images, or by authoring parts of the observing manual. The Planetary Nebula Club creation was truly a BBAA effort. I think it’s a shame, therefore, that more BBAA’ers haven’t completed the program and earned the pin. So if you are looking for an observing program to complete, why not our very own? There was never a better time to start. More than half the list is visible right now and no less than 31 of our 110 PNe are optimally placed in August. Hence the title of this epistle. It is my intention to spark an interest in the program and suggest the objects that might be bagged in the coming weeks. Many of you have no doubt observed these objects already, so please chime in and share your impressions of them. As is true of the entire list, our August selection contains both well-known showpieces and some seldom mentioned objects that you might not consider tracking down if not for this program. There are no less than 17 of the 31 August objects that I would describe as “stellar”. I must confess that I am not the biggest fan of these tiny objects and had I been the sole arbiter of the list it would have contained far fewer of these. -

Sticking with our vision of bring- ing simplicity to cloud management, this release comes with improvements in the recently added Cloud View portal, designed for end users. One significant advantage of the new portal is the ability to control flows, groups of intercon- nected Virtual Machines that conform a service. Based on this Cloud View, a Virtual Datacenter administrators view has been included (VDCAdmin View), which enables VDC admins to easily manage the VDC users and resources. An important highlight in this release is a vast improvement to the hybrid model. Support for two new public cloud providers have been added, widening the range of possibilities to offload VMs in case the local infrastructure is 1 OpenNebula 4.8 Release Notes, Release 4.8 saturated. The hybrid model in OpenNebula enables a centralized management of both local and remote resources for the cloud administrator, and a transparent consumption of these resources for the end user.
