AAVSO and/or BAA-VSS. - posted in Observational Astrophysics: This topic is likely to be of interest primarily to Brits (if anyone at all) but contributions from everyone are most welcome. To set the scene, I was a keen VS observer some years ago, purely visual in those days, who submitted my observations to the British Astronomical Association - Variable Star Section, aka BAA-VSS, and.

Abstract. The American Association of Variable Stars (AAVSO) is an international organization that coordinates, collects, evaluates, and archives variable star observations, analyzes and publishes variable star data, and makes them available to the astronomical by: 4.

Instead, this book tells the story of how an organization composed mostly of amateurs, the American Association of Variable Star Observers (AAVSO), grew to become a major source of information on stars that pulsate, explode, or otherwise change in brightness.5/5(4).

The American Association of Variable Star Observers - better known as the AAVSO - has masses of variable star results in it on-line database. The question is. This fascinating portrait of an amateur astronomy movement tells the story of how Charles Olivier recruited a hard-working cadre of citizen scientists to rehabilitate the study of meteors.

ByOlivier and members of his American Meteor Society had succeeded in disproving an erroneous idea about meteor showers. Using careful observations, they restored the public’s trust in predictions. Last Observation Received: 2 min 31 sec ago by SPP - Philip Sullivan (US) TT CRB May B.

Now, it has evolved into an International Organization with members and observers from both the professional and non-professional astronomical community, contributing photometry to a public photometric database of ab variable objects, and using it for.

Automation isn't easy though, and depends largely on the quality of your mount. AAVSO and VSS observations of eta Car don’t go back anywhere near that far, so our input there will be very significant. Our historical observations are those of John Tebbutt (). He observed R and eta Car for 15 or so years in the late 19th century.

Classical Cepheids (also known as Population I Cepheids, Type I Cepheids, or Delta Cepheid variables) are a type of Cepheid variable are population I variable stars that exhibit regular radial pulsations with periods of a few days to a few weeks and visual amplitudes from a few tenths of a magnitude to about 2 magnitudes.

There exists a well-defined relationship between a classical. Observing Variable Stars The study of the heavens, at some point, brings one to the realization that the sky is not constant. The moon crosses the sky in its monthly pilgrimage, changing its appearence daily. Comets appear, brighten and fade away.

Meteors zip across the sky to the delight of most. Characteristics. Covering square degrees, Pegasus is the seventh-largest of the 88 constellations. Pegasus is bordered by Andromeda to the north and east, Lacerta to the north, Cygnus to the northwest, Vulpecula, Delphinus and Equuleus to the west, Aquarius to the south and Pisces to the south and east.

You now have a choice to star hop by either using the finder (if you have one) or by using a low power eyepiece in the main scope. A good finder scope (8x50 and larger) will show many of the stars on the AAVSO atlas.

One advantage of using the main scope is that you can get the. Founded inthe AAVSO boasts over members and observers and is the world's largest non-profit organization dedicated to variable star observation.
