  Airmass & Scintillation Calculator

This calculator will give you an approximation for airmass and scintillation (for small and modest aperture telescopes).

Date of Observation

JD or yyyy/mm/dd/hh/mm/ss (UT)

Observer Latitude

dd.ddd. North is positive, South is negative

Observer Longitude

dd.ddd or dd mm ss.
West is - or W, East is + or E (12.123E or +12.123)

Target RA

degrees or hh:mm:ss or hh mm ss

Target Dec.

degrees or dd:mm:ss or dd mm ss

Aperture

cm (optional - only required for scintillation)

Integration Time

seconds (optional - only required for scintillation)

Note: This calculator uses cookies to optionally remember your Latitude, Longitude and Aperture settings. If you do not have cookies enabled it will still function.

Also check out Airmass Calc, a Windows-based airmass calculator with a GUI, which is available here.
