Sun speed is a function of the time of year. the sun will have an exact speed today, will be slightly slower tomorrow as the sun moves north a tiny bit. You could pick any day from a date picker and get the speed of the sun for that day.

As caused by the distance from Earth to sun changing around the equinoxes etc? I haven't looked into it too much, does the data change year on year? I assume you are wanting orbital circular velocity? If it changes year on year then the app would need to recover this data annually or manually perhaps. I will check it out and if it isn't a huge job I will try and get it in the update cycle in the next month or so

The calculation is currently based on sea level on a spheroid of r 3959 miles. The ability to enter your own formulas is something I have considered, but as the baseline that seems to be in dispute is the generally accepted one, i chose that. Of course it requires you either manually account for your own altitude or work at sea level.

Some have asked for a setting to enter the observer altitude.

@David, speed of the sun.. ok thats a possible one though I guess a more advanced function for people doing shorter range observations?

As I said, any suggestions welcome.


If there are any particular formulas that people use regularly they would like including in the App's setup I will be happy to publish an update.

Cheers

My brother asked me to make him an app to help him in his calculations whilst out and about. He was using Android, but I have also made one for iPhone and iPad.
It isn't a big download and requires no internet so is good for tablets with no network etc.

Android version is at https://play.google.com/store/apps/details?id=com.visicomscientific.scottforshaw.earthcurvecalculator&hl=en

and the Apple version is at  https://itunes.apple.com/us/app/earth-curve-calculator/id1071498458?mt=8

I hope it of use to anyone who is interested in this subject, if there are enough requests then updates/modification suggestions welcome.
