This tool helps you calculate the timing and visibility of upcoming solar or lunar eclipses in your location.
This eclipse estimator allows you to determine whether a solar or lunar eclipse will be visible from your location.
How to Use: Enter your latitude, longitude, altitude, and the date you wish to check for an eclipse. Click “Calculate” to get the result.
How It Calculates: The calculator uses spherical trigonometry to determine the positioning of the sun, moon, and earth relative to the given location and altitude. It determines if the sun or moon will be obscured.
Limitations: This estimator does not account for long-term orbital changes or atmospheric conditions that might affect visibility. Accuracy may decrease the further the selected date is from the present.
Use Cases for This Calculator
Calculate Eclipse Duration
Enter the start and end times of the eclipse along with your location to estimate how long the eclipse will last. The calculator will consider the duration based on the provided information.
Estimate Shadow Size
Input the distance between the observer and the object casting the shadow during the eclipse. The estimator will then determine the size of the shadow projected during the event based on the provided data.
Predict Path of Totality
Specify your location and the duration of the eclipse to predict the path of totality. The calculator will show you the area where the eclipse will be fully visible during its peak.
Calculate Magnitude of Eclipse
Enter the apparent diameter of the Sun and Moon, as well as their distances from Earth to calculate the magnitude of the eclipse. The estimator will provide a numerical value representing the eclipse’s intensity.
Estimate Eclipse Visibility
Provide your geographical coordinates and the eclipse details to estimate its visibility from your location. The algorithm will determine if the eclipse will be visible to you based on the input.
Calculate Contact Times
Input the start and end times of the eclipse to calculate the contact times of various eclipse phases like first contact, second contact, third contact, and fourth contact. The estimator will provide you with precise timings for each phase.
Estimate Eclipse Altitude
Specify the time, location, and eclipse details to estimate the altitude of the eclipse. The calculator will provide you with the angle at which the eclipse will be visible from your location.
Predict Eclipse Type
Input the characteristics of the eclipse such as annular, partial, or total, along with the position and time to predict the type of eclipse. The estimator will classify the eclipse based on the provided data.
Calculate Eclipse Velocity
Specify the distance the Moon travels during the eclipse and the duration to calculate the velocity of the eclipse. The calculator will provide you with the speed at which the eclipse shadow moves across the Earth’s surface.
Estimate Eclipse Intensity
Enter the luminosity of the Sun and the Moon to estimate the intensity of the eclipse. The estimator will calculate the brightness level of the eclipse based on the provided values.
