Typical settings for (RefLink[AltitudeMethod, paclet:ref/AltitudeMethod]) include:

The typical default setting for (RefLink[AltitudeMethod, paclet:ref/AltitudeMethod]) is "TrueAltitude".

Allow for atmospheric refraction when computing the altitude:

SunPosition[LinguisticAssistant,DateObject[{2014,9,4,19,5},TimeZone->-5],AltitudeMethod->"ApparentAltitude"]

MoonPosition[LinguisticAssistant,DateObject[{2014,9,4,19,5},TimeZone->-5],AltitudeMethod->"ApparentAltitude"]

The default setting for (RefLink[AltitudeMethod, paclet:ref/AltitudeMethod]) simulates no atmospheric refraction:

SunPosition[LinguisticAssistant,DateObject[{2014,9,4,19,5},TimeZone->-5]]

MoonPosition[LinguisticAssistant,DateObject[{2014,9,4,19,5},TimeZone->-5]]
