In celebration of the AAVSO Centennial, we have created A Century of Variable Star Observing: 1911-2010, a 13-month, full-color calendar that showcases the AAVSO and the people who have made it the dynamic institution it is today. Give it as a gift to yourself, the AAVSO'er or variable star observer or amateur astronomer in your life, the history of astronomy or science fan you know, the student of women in science...

The AAVSO Centennial Calendar is full of images - nearly 200 of them! - and includes artwork pages on:
 ► members, observers, and friends of the AAVSO
 ► observers and their observing equipment and observatories
 ► women in the AAVSO
 ► Directors and Recorders
 ► staff members and volunteers
 ► AAVSO Headquarters locations
 ► AAVSO charts
 ► AAVSO reports, showing how submitting observations has evolved
 ► the AAVSO logo

There are too many photographs of people in the calendar to include identifications of everyone there. Thus, we have created files of identifications and placed them on the AAVSO website for your reference (perhaps to download, print, and keep near the calendar).

The date page for each month includes:
 ► Julian Dates
 ► UT dates and times of lunar phases
 ► standard civil and religious holidays
 ► 2011 AAVSO meeting dates
 ► AAVSO historical tidbits - lots and lots of them!

What is the remarkable coincidence about all of the AAVSO Recorders and Directors?  Exactly when did the AAVSO leave Harvard College Observatory and where did it go? When did HCO approve of the AAVSO's use of blueprint finding charts? Just what is the "projected star logo"? When did Leslie Peltier make his first observation (and what star did he observe)? Danie Overbeek? John Bortle? Who made the 10 millionth AAVSO observation and when? The who's, what's, where's, and when's of much AAVSO history is given on these pages.

The front cover shown above highlights the formal AAVSO organization meeting held in 1917. Below are two additional samples from the calendar - the date page for October 2011 and the back cover.

The date page shows how each month's information is arranged and gives you an idea of the AAVSO history covered - October has always been a busy month for the AAVSO!
