Ever wanted to know exactly when the sun is due to rise or set, when the moon will make an early evening appearence when its still light, or where a planet such as jupiter might be visible.
The Sundroid Sunrise Sunset app for android devices is all that and more.. I was really impressed by the level of detail that is available in an app. Whilst there is a free version, I plumped for the pro version at GBP 1.99.
It is extrmely useful for many reasons, however my main reason is photogrpahy. It allows me to know when to get to a good spot at the right time. I had never realised before now that there is a Golden Hour after sunrise and before sunset when the sun is at an optimal angle for good photos.
It has many other great features including:
- Sunrise and sunset times with azimuths
- Civil, nautical and astronomical twilight times
- Solar noon with elevation
- Golden hours
- Length of daylight
- Rise, set and transit times for the moon, Mercury, Venus, Mars, Jupiter, Saturn, Uranus and Neptune
- Lunar phase and illuminated fraction
- Track the azimuth and elevation of the sun, moon and planets individually or together
- Solar and lunar eclipses 2000-2020
- Solstices and equinoxes 2000-2020
- Earth aphelion and perihelion 2000-2020
Most of the above I will probably never use.. but interesting non-the less.
