Template:Infobox lunar eclipse/sandbox

Template documentation[view] [edit] [history] [purge]

{{Infobox lunar eclipse}} is an {{Infobox}}-based template that acts as a summary of information for an article on a specific lunar eclipse. It is largely designed to present the most relevant information on an eclipse to a casual astronomer, and intentionally omits highly specific details such as geocentric coordinates and delta T to avoid information bloating and keeping the infobox as short as reasonably possible. This infobox is designed with a subheading parameter, two image parameters, one caption parameter, sixteen cell parameters and two succession link parameters. Its syntax makes use of a collapsible list, two {{#if:}}, and two {{#ifexist:}} parser functions, along with a hCalendar microformat.

Parameters

Parameter(s)	Description
type	Specifies in the infobox headline what type of eclipse the event was. This parameter has three defined inputs, all of which correspond to a subheader style. The input total can be used for a total eclipse, partial for a partial eclipse, and penumbral for penumbral eclipses.
image	This first image parameter displays an image thumbnail at the size of the user's preferences as specified in their settings. This parameter is intended to be used to display a photograph of the lunar eclipse, preferably in a tight square crop filled with a full disc view of the moon. This image would be an example of the kind intended to be displayed in this parameter. Omit the File: prefix in the filename when pasting it as an input to this parameter.
alt	This image alt caption parameter allows for the input of an alt caption, which displays a description of the image when it fails to load. A simple description such as "A dark-red coloured Moon" should suffice.
caption	This image caption parameter is intended to describe the photograph used in the image parameter above it, formatted as follows: the point during the eclipse it was taken, the location on Earth it was taken from, and the time it was taken in UTC. For example, "Totality from Wollongong, New South Wales, 09:48 UTC"
date	This parameter is used to display the date of the eclipse in Coordinated Universal Time (UTC), formatted in day-month-year. If the eclipse's penumbral stages occur across two dates in UTC, input only the date in which greatest eclipse occurs. For example, the July 2019 lunar eclipse occurs over 16–17 July 2019, though greatest eclipse occurs on 21:30:45 UTC on 16 July. Therefore, "16 July 2019" should be the input for the date.
gamma	This parameter is used to display the gamma value of an eclipse, with positive values written as a decimal number and negative values written with a minus sign (−) as a prefix. For example, the gamma of the May 2022 lunar eclipse is written as "-0.2532", and the gamma value for the May 2021 lunar eclipse is written as "0.4774".
magnitude	This parameter is used to display either the penumbral or umbral magnitude of the eclipse. If an eclipse is partial or total, the umbral magnitude is written in this parameter, while the penumbral magnitude is written in this parameter for penumbral eclipses.
saros_ser, saros_no	These parameters are used to display both the saros series that a lunar eclipse belongs to, and which entry in the series it represents in parentheses. The first use is achieved using the saros_ser parameter, which uses the {{#ifexist:}} parser function to check if a wikipedia article about a particular series exists. If it does, it automatically creates a wikilink to that article, and if not it simply displays the input as normal text. The second use is achieved using the saros_no parameter, where both the entry number the eclipse represents is displayed along the total amount of eclipses in the series, preferably conjoined with the preposition "of". For example, the June 2010 lunar eclipse is described in this parameter as "58 of 84" in Lunar Saros 120.
totality, partiality, penumbral	These parameters are used to display the amount of time each phase of the eclipse lasted, intended to be formatted in worded minutes and seconds. For example, 102 minutes, 50 seconds. totality is used to display how long the totality phase of the eclipse lasted, partiality for the partiality phase, and penumbral for the penumbral phase. Omit the totality parameter completely if it is only a partial eclipse, and omit both totality and partiality if it is a penumbral eclipse.
p1, u1, u2, greatest, u3, u4, p4	These parameters that form part of the collapsed "Contacts" section of the infobox are used to detail the exact times, in Coordinated Universal Time (UTC), the various contact points of the eclipse. For example, u1 and u2 correspond to the points where the moon first enters the umbra (U1 contact) and is completely enveloped by it (U2). The greatest parameter corresponds to the point at which the moon is at its greatest eclipse. If an eclipse occurs over two dates, be sure to note the date that is not represented in the date parameter. For example, u4 for the July 2019 lunar eclipse should be set to "00:17:36 (17 July)"
previous, next	These succession parameters at the bottom of the infobox are used to display the previous and next eclipse in chronological order and regardless of eclipse type, relative to the current one being detailed. The {{#ifexist:}} parser function is used in this parameter to automatically create a wikilink if a wikipedia article on the previous and/or next eclipse exists. For example, setting either parameter to January 2018 will set the wikilink to January 2018 lunar eclipse.

Microformat

The HTML markup produced by this template includes an hCalendar microformat, which makes the event details parsable by computers, either acting automatically to catalogue article across Wikipedia, or via a browser tool operated by a person, to (for example) add the subject to a calendar or diary application. Within the hCalendar is a Geo microformat, which additionally makes the coordinates (latitude & longitude) parsable, so that they can be, say, looked up on a map, or downloaded to a GPS unit. For more information about the use of microformats on Wikipedia, please see the microformat project.

Dates will only be included if you use {{Start date}} or {{End date}} (use the former for single dates, but do not use any of these if the date is before 1583 CE). {{End date}} requires that a time be specified, but display of this time may be suppressed by adding |nodate=yes to the end.

To include a URL, use {{URL}}.

hCalendar uses HTML classes including:

• attendee
• dtend
• dtstart
• location
• summary
• url
• vevent

Geo is produced by calling {{coord}}, and uses HTML classes:

• geo
• latitude
• longitude

Please do not rename or remove these classes nor collapse nested elements which use them.
Also, when giving coordinates, please don't be overly precise.
