Lunastro
Lunastro is a python library for calculating astronomical data, such as, but not limited to:
- RA of the sun
- Hour angle of the sun
- Declination of the sun
- Longitude of the Sun's Ascending Node (Omega)
- Solar Geometric mean Anomaly
- Solar Geometric mean Longitude
- True Solar Longitude
- Distance to the sun
- Local sidereal time (accurate to the second)
- Sun altitude
- Sun azimuth
- Moon Position
Usage
Lunastro's functions return objects of information. Here is a list of each function and what it returns:
Solar Data
latitude = 47.6101 # Bellevue WA latitude
solar_data = getSunData(latitude) # get the solar data
This returns:
| Attribute | Description |
|---|---|
| dec | current solar declination |
| hour_angle | current solar hour angle |
| ra | current solar right ascension |
| long_omega | Longitude of the Sun's ascending node |
| true_solar_anomaly | true solar anomaly |
| true_solar_longitude | true solar longitude |
| geo_anomaly | geometric mean anomaly of the sun |
| geo_long | geometric mean longitude of the sun |
| dist | distance to the sun in miles |
Altitude of the Sun
# lat and long are of Bellevue WA
latitude = 47.6101
longitude = -122
alt = altitude(latitude, longitude)
This returns the altitude of the sun in radians
Azimuth of the Sun
# lat and long are of Bellevue WA
latitude = 47.6101
longitude = -122
azi = azimuth(latitude, longitude)
This returns the azimuth of the sun in radians
Local Sidereal Time
# longitude
long = -122
time = localSiderealTime(long)
This returns the local sidereal time as an object:
| Attribute | Description |
|---|---|
| raw | raw sidereal time |
| hour | hours of sidereal time |
| minute | minutes of sidereal time |
| second | seconds of sidereal time |
Moon Positioning
# lat and long are of Bellevue WA
lat = 47.6101
long = -122
moon_pos = getMoonPosition(lat, long)
This returns the positioning of the moon as an object:
| Attribute | Description |
|---|---|
| azimuth | azimuth of the moon |
| altitude | altitude of the moon |
| distance | distance to the moon in KM |
| parallacticAngle | parallactic angle of the moon |
