ASTRO TIPS Lunar and Monthly Calendars By Thad Floryan This edition of the ATT Astro Tip represents a bit of a departure from its normal tip fare. Friend of the magazine, Thad Floryan, has posted a collection of excellent calendars on ATT’s forum, http://tech. groups.yahoo.com/group/astronomytechn ologytoday/ and we thought we’d share them with you here. Downloadable PDFs can be found in the files section of the ATT group. Thad has also added links to the calendars at the AstronomyHacks forum, http://tech.groups.yahoo.com/group/astro nomyhacks/, source of more than a few of the tips that have been shared in these pages recent years. About the calendars, Thad humbly notes: “They’re not actually ‘my’ calendars other than the fact I ran two programs that were authored by another person to create the specific calendars I posted. In other words, the only credit I can take is that of an operator of the two programs. :-)” “Here are the present author’s pages for the C versions of the programs: (1) http://pcal.sourceforge.net/ (PCAL and Submit Your Astro Tip! Astronomy Technology Today regularly features tips, tricks, and other novel solutions. To submit your tip, trick, or novel solution, email the following information: • A Microsoft Word document detailing your tip, trick or novel solution. • A hi-resolution digital image in jpeg format (if available). Please send your information to tips@astronomytechnologytoday.com tips, tricks and novel solutions LCAL PostScript Calendar Programs), which page can be considered to be the ‘manual’ for both the PCAL and LCAL programs, and the page also has some examples of the output of both programs; and (2) http://sourceforge.net/projects/ pcal/ for the downloads. Both the source code in a UNIX tar file and executables of PCAL and LCAL for Windows are available at the later URL.” “Again, please note both programs were originally written on and for UNIX systems and subsequently have been ported to Linux, MacOS and Windows.” With lunar-phase apps just a few swipes away via the smartphones and tablets that are becoming so integral to our daily lives, it’s easy to forget just how handy it is to have a printed calendar posted nearby – a calendar that tell us at a glance precisely what the Moon is about, no swiping needed. Thanks, Thad! 72 Astronomy TECHNOLOGY TODAY
