v3.0.1

Compare Source

Patch release: correct moon phase timing. No API changes.

• Fixed MoonIllumination.Phase and Waxing near new and full moon. The phase was timed by right ascension and could pass 0 / 0.5 up to about 3 hours away from the real new or full moon, enough to put a full moon on the wrong calendar day in some time zones. It is now derived from the Moon–Sun difference in ecliptic longitude, so 0, 0.25, 0.5 and 0.75 match the USNO phase times, and Waxing flips exactly at the full moon. Port of SunCalc JS v2.1.1 (https://github.com/mourner/suncalc/releases/tag/v2.1.1).
  Resolves: mourner/suncalc#190

148 USNO phases, 2000–2050	3.0.0	3.0.1
Mean error	60.5 min	0.55 min
Worst case	over 3 h	1.83 min

Fraction and Angle are unchanged. Phase values can shift slightly near the phase boundaries; for example 2013-03-05 00:00 UTC is now 0.75320 instead of 0.75280.

v3.0.0

Compare Source

3.0.0 is a breaking release. Sun and moon phases now work in the observer's local calendar day and return local times, so you no longer have to convert UTC results or worry about which day you get near midnight. See Migrating to 3.0.

// 2.x: UTC in, UTC out, and late-evening inputs could return tomorrow
SunCalc.GetSunPhases(new DateTime(2013, 3, 5, 0, 0, 0, DateTimeKind.Utc), 50.5, 30.5);   // Sunrise 04:33 (UTC)

// 3.0: any time on the day, results at the same offset
SunCalc.GetSunPhases(new DateTimeOffset(2013, 3, 5, 18, 30, 0, TimeSpan.FromHours(2)), 50.5, 30.5);   // Sunrise 06:33 +02:00

• Breaking: GetSunPhases and GetMoonPhase now take a DateTimeOffset and return the observer's local calendar day at that date's own UTC offset, whatever its time of day. Every returned time comes back at the same offset, so no manual conversion is needed. Port of SunCalc JS v2.1.0 (https://github.com/mourner/suncalc/releases/tag/v2.1.0) day handling.

• Breaking: SunPhase.PhaseTime and MoonPhase.Rise, Set, Transit and LowerTransit are now DateTimeOffset. Calls passing a DateTime to GetSunPhases or GetMoonPhase no longer compile (CS0619) and point to the migration guide, so every place that needs a decision is flagged rather than silently changing behaviour.
• Added TimeZoneInfo overloads of GetSunPhases and GetMoonPhase that handle daylight saving days correctly: they cover the whole 23 or 25 hour local day and report each time at the zone's offset at that moment.
• Added moon Transit and LowerTransit (highest and lowest point of the moon) to MoonPhase, reported even when the moon is below the horizon. Port of SunCalc JS v2.1.0 (https://github.com/mourner/suncalc/releases/tag/v2.1.0).
  Resolves: mourner/suncalc#72
• GetMoonPhase now scans the full local day, including evening moonrises west of Greenwich that the UTC-day scan used to miss.
• GetSunPosition, GetMoonPosition and GetMoonIllumination now take a DateTimeOffset; existing DateTime arguments still compile and give the same results.

v2.0.1

Compare Source

• Fixed GetMoonPhase reporting AlwaysDown on days the moon never sets: the no-crossing flag is now decided from the highest moon height sampled over the whole day. Port of SunCalc JS v2.0.1 (https://github.com/mourner/suncalc/releases/tag/v2.0.1).
  Resolves: mourner/suncalc#186
• Fixed GetSunPhases returning the previous day's events for longitudes just west of the antimeridian. Sun phases now come from the local solar day containing the given date; for early-morning inputs, pass a time near local noon. Port of SunCalc JS v2.0.2 (https://github.com/mourner/suncalc/releases/tag/v2.0.2).
  Resolves: mourner/suncalc#187
