Please bring a side dish, only for 3-4 people/person, and let us know ASAP what you are bringing. Thank you.

6:00 PM Speaker: Dave Cotterell, North York Astronomical Association, Ontario, Canada
Program: A Guide to Double Star Observing

Dave has been in amateur astronomy for over 50 years, and has owned refractors, Newtonians and Catadioptrics
from 2" to 20" diameter. Though he has always been an observer of all types of objects, his first love
continues to be double stars. Recently he has been doing high-resolution imaging of doubles with a 202mm Maksutov.
His goal is to be able to make scientifically valid measurements of the separations and position angles of double stars.


7:00 PM Dark Sky Star Gaze
Focus on Double Stars: Alberio, Almaak, Mizar/Alcor, and more. . .

Please arrive before dark. Park with your headlights toward the road.
Bring what you have of planisphere, binoculars, telescope.
Wear socks, shoes, hat, layered clothing.




ACA Meeting
November 07, Friday, 7:00 PM at
GRU The Public is invited!

Program: AGN = Active Galactic Nuclei
or "Radial Distances of Dust Sources in Low Ionization Broad Absorption Line Quasars"
Recent studies of very unique quasars (FeLoBALs) have shown that these objects have the potential
to shape both super massive black holes and their host galaxies.
Unfortunately, these objects tend to be extremely reddened due to dust.
This dust poses a large problem for FeLoBAL (and LoBAL) studies that attempt to determine the energies of these quasars.
Our search through objects in the Sloan Digital Sky Survey's vast database has uncovered a set of these FeLoBALs
that has shed light upon the locations of dust sources and potentially their nature.

Speaker: Jay Dunn,
2007 PhD GA State University, 2008-10 Post Doctoral Researcher, VA Polytechnic Institute and State University,
2010-11 Temporary Associate Professor, ASU (GRU) Since 2012 _________ at Perimeter College near Atlanta, teaching _____
Jay has mentored at least eight ? college students in research that lead to published papers.
His research focuses on Spectral Analysis of FeLoBAL Quasars and Ultraviolet Studies of Active Galactic Nuclei. http://www.jstor.org/stable/10.1086/500961.
Jay presented a program to our club in 2011 about Outflows in Active Galactic Nuclei, and in 2012 Interstellar Medium.
He is a member of our club, and sometimes comes to help us on Astronomy Night &/or at SEED.
We are pleased to welcome him back again, and look forward to his contributions and keeping in touch.

Refreshments:
Lunar Observing after the meeting

Wear layered clothing.



Beginners to experts can benefit
from the abundance of knowledge, skill, and enthusiasm
at our local meetings and star parties.
Astronomy is not a simple sport. Get help to get good.
