Corrections

Astronomical Calendar 2013:
Page 2, top right: the small calendar for 2012 was inadvertently retained, though the version for 2013 had been plotted and is shown here. If you wish to have this illustration on paper and cannot print it yourself the author is willing to print and mail it to you.
64, charts for Comets C/2012 F6 Lemmon and C/2011 L4 PANSTARRS: constellation label “Sagittarius” should be “Aquarius.”
Page 72, occultations, Table I, line 3, Jan. 22: for “Europe, N America” read “S America.”

Astronomical Calendar 2012:
Pages 8-28 (left-hand pages): the running heads at the tops of these pages incorrectly read “Astronomical Calendar 2011”. The material on the pages, however, is correct for 2012
Page 37: the “Strip-chart of the Moon” for 2011 was accidentally retained. The 2012 chart can be found here. (This is a PDF document.) You can obtain a free print of the correct page from CustomerService@UniversalWorkshop.com

Psge 75: the last cross-heading should read “Lookahead to 2012”.

Astronomical Calendar 2010
Page 27: the lines for November 22-30 were dropped. The corrected page can be found here. (This is a PDF document.)

The Thousand-Yard Model
Page 11: the 3rd paragrapj, truncated in printing, should read:
“Since pecans, pinheads, peanuts and especially peppercorns cannot always be readily found when another demonstration is called for, I keep at least one planetary system on hand, in one of the small canisters in which 35-millimeter film is sold.”
Page 18: the last paragraph of section “The emptiness of space” should have a final line:
“important gravitational influence on the Earth.”
