This plugin displays data of interest to amateur astronomers. It is calculated from user-provided location and date information. 
The plugin is called from a WordPress shortcode, and the parameters are specified in the shortcode. The following parameters are 
required, in any order:
<ul>
<li>lat : Lattitude of location in fractional degrees (e.g. 30.8910). Positive is north, negative is south of equator</li>
<li>long : Longitude of location in fractional degrees (e.g.-98.4265). Positive is east, negative is west of the UTC line</li>
<li>timezone : Timezone name, must be value recognized by PHP. See <a href="http://php.net/manual/en/timezones.php" rel="nofollow ugc">http://php.net/manual/en/timezones.php</a></li>
</ul>
These parameters are optional:
<ul>
<li>name : The name of the location to be calculated</li>
<li>days : The number of days of data to display. Must be a value from 1 to 10. Defaults to 3 if not specified. </li>
</ul>
Shortcode Examples:
<ul>
<li>stars-at-night name=Chennai lat=13.08 long=80.26 timezone=Asia/Kolkata days=1</li>
<li>stars-at-night name=”COE Observing Field” lat=30.891 long=-97.4265 timezone=America/Chicago days=10</li>
</ul>
You can also display the individual data tables via more specific shortcodes:
<ul>
<li>stars-at-night-sun-moon name=”Mount Kilimanjaro” lat=-2.55 long=37.55 timezone=Africa/Nairobi</li>
<li>stars-at-night-planets name=”Ushuaia” lat=-54.8 long=-68.33 timezone=America/Argentina/Ushuaia</li>
<li>stars-at-night-iss name=”Mount Burnett Observatory” lat=-37.9 long=145.4 timezone=Australia/Melbourne days=7</li>
</ul>
The output consists of simple HTML tables:
<ul>
<li>Sun/Moon table: The times for sunrise, sunset, moonrise, moonset, morning astronomical twilight, and evening astronomical twilight for the specified days (max 10 days).</li>
<li>Planets table: The times and visibility for the planets, for the current day.</li>
<li>ISS table: The times and directions for visible ISS passes over the specified days (max 10 days).</li>
<li>(REMOVED) Iridium flares table: The times and directions for visible Iridium flares over the specified days (max 7 days).</li>
</ul>
