AstroUtilitiesAlmanac Method

public static void Almanac(
	EventType typeOfEvent,
	int year,
	double siteLatitude,
	double siteLongitude,
	double siteTimeZone,
	ILogger almanacLogger
)

Public Shared Sub Almanac ( 
	typeOfEvent As EventType,
	year As Integer,
	siteLatitude As Double,
	siteLongitude As Double,
	siteTimeZone As Double,
	almanacLogger As ILogger
)

Parameters

typeOfEvent  EventType

The rise-set or twilight times event that the almanac will describe.

year  Int32

Year of the almanac.

siteLatitude  Double

Latitude of the site for which the almanac is required (-90.0 to +90.0). North positive, south negative.

siteLongitude  Double

Longitude of the site for which the almanac is required (-180.0 to +180.0 ). East positive, west negative

siteTimeZone  Double

Time zone of the site for which the almanac is required (-12.0 to +14.0). East positive, west negative

almanacLogger  ILogger

An ILogger component to which the almanac will be written.

At latitudes greater than 60N or 60S it is possible for there to be two rises or sets in a given 24 hour day, hence results are aggregated into two EventTime lines. If, for a given day, all months have only 0 or 1 event only the first event times line is included. If any day has two events then the second event times line is included with the same day number as the first event times line.

The following symbols are used in the almanac:

• **** - Visible at all times - risen all day.
• ---- - Never visible - set all day.
• //// - Lighter than the twilight threshold all day long.
• ==== - Darker than the twilight threshold all day long.
• Blank space indicates no events on this day.

The expected output for Moon rising / setting using the parameters: Year=2012, Latitude=75N, Longitude=75W, TimeZone=-5h is given at the end of this example.
