🔥 Analemma calculator – time and sun equation
shared
Use with us Illima Calculator To visualize the annual shape of Figure 8 of the sun and calculation Time equation For any day of the year. Generating sun correction schedules, exploring seasonal differences, and see how monitoring time affects the direction of the pattern.
Using a alteemma calculator
Follow these steps to analyze the differences of the solar position:
- Select: Choose from this year ± 5 years to explore previous or future patterns
- Take time today: A slice from 6 am to 6 pm to see how the monitoring time affects the direction of Elima
- Transfer according to today: Use the scrolling bar today or animation controls to track the annual sun trip
- Export data: Download CSV Summary, CSV Sundial, SVG graphics for Analemma, or time plan equation from the drop -down menu
The calculator shows simultaneous visible: the classic figure Figure 8 (Solar energy deviation Opposite Time equation) And separation Time equation The graph throughout the year. The yellow sun marks follow your position on both charts by date.
Analemma tool features
The interactive screen includes seasonal signs of moderation and coup.
At the presentation of the current year, the green “Today” index shows your position on the annual cycle of the land. to hit He plays A button to move the entire year – Watch how the sun goes near rock bottom (Early January) and slows down near Avenueon (Early July).
the The time of today Slider reveals how Analemma changes based on observation time. At noon, you see the classic vertical shape 8. The morning hours are tilt east, in the afternoon in the west. This reflects Clock – Your view perspective in relation to the long long line.
Sun corrections
Sundayals displays solar energy time, not an hour time. The time equation tells you about the number of minutes that must be added or put up to get a delicate time from the hour from Sundial. In mid -November, Sundayals runs 14.7 minutes quickly. In mid -February, slowly 14.6 minutes.
export Sun correction table For monthly reference values. CSV includes instructions: The positive equation of time means that Sundial is slow (add -on), which means that it is fast (put the minutes).
Data export options
It serves three different needs export formats:
- CSV data: The daily equation of time and the values ​​of deviation for the entire year
- Sun correction tableMonthly corrections with application instructions
- SVG graphicsExporting either the visualization entitled Wrong and Design
Illima understand
the Ilima Effects where the sun appears when filmed at the same time daily throughout the year, and reveal how Solar time It varies from the time of the hour – sometimes more than 16 minutes (in early November). Here are some other major terms.
Main definitions
Time equationThe difference between the apparent solar time and the average solar time, ranges between about +16 to -14 minutes. This difference affects sunlight, Solar panelsAnd astronomical notes.
Solar energy deviation: The corner distance of the sun north or the south from the celestial equator, from +23.5 degrees at the summer overthrow to -23.5 degrees at the winter coup.
Solar time: Time is based on the actual position of the sun. Solar noon It occurs when the sun crosses your local length line (its highest point for today).
Clock: The corner distance of the sun from the local length line, measured west. Every hour represents 15 degrees of Earth’s rotation.
rock bottom: The point is in the orbit of a celestial body when it is Close To the sun. For Earth, the bottom occurs around January 3 of each year, when we are closer to the sun and move faster in our orbit.
Avenueon: The point is in the orbit of a celestial body when it is far From the sun. The Earth reaches APHELION around 4 July of each year, when we are more than the sun and move slower.
Analemma dilemma: Why style Figure 8?
A feature of the Earth’s orbit creates altimma:
Oval: The Earth rushes when it is closer to the sun (be present) and slows down when it farther (Aveliion). This variable tropical speed means that the solar days are not exactly 24 hours – they are slightly longer or shorter depending on the time of the year.
A central tilt of 23.5 degreesTilt the Earth changes the speed of the sun shown across the sky. Near the coup, the movement of the sun is mostly east and west. Close to moderation, it has a stronger component than the north and the south.
Without the elliptical orbit, Altimma will be a straight line from the north and south. Without the pivotal inclination, it will be the east and west. Mash ‘Em and got the elegant shape 8, with transit points on April 15 and September 1.
Does Alticmma change depending on your place?
No, healemma is identical everywhere on the floor. What are the changes with the site is only the trend of al stlemma in the sky and any parts that appear above the horizon. On the columns, you will only see half the style. In the equator, you see it stand vertically.
So on the ground, whether you are in Bostonand BeijingOr Buenos AiresFigure 8 looks itself. (Nevertheless Sons It will look different!)
Methodology and technical notes
The calculator does implement The approximation formula for the time equation:
E = 9.87 sin(2B) - 7.53 cos(B) - 1.5 sin(B)
where:
- E: Time equation in minutes
- for: A fracture year in the Radi, calculated that it is B = 2Ï€ (N-81)/364
- NA day of the year (1-365/366)
