Sun Angle Calculator - Hour by Hour Solar Position and Shadow ... - DQYDJ
Written by:PKNeed precise sun angle data for a specific date and location? Our sun angle calculator provides hour-by-hour solar altitude and azimuth angles, plus shadow length calculations for any object height. Also, find an interactive visual mode that shows the sun's complete path across the sky and some detailed angle calculations. Features of the sun angle calculatorThe sun angle calculator only requires a location and a date/time entry to start (which you can autofill, if you like!), but it has a few customization options:Hour-by-hour data: Complete 24-hour solar position table for any date. You can switch between 12h (AM/PM) and 24h time with the selector.Visual solar analysis: Click Visual to see the sun's complete daily journey as an interactive arc diagram with real-time sun positioning (when viewing today's date), compass grid, and elevation markers.Shadow calculations: Enter an object's height and the tool will return shadow lengths throughout the day. You can switch between feet & inches and meters with the dropdown. (For more detail, see the shadow length calculator)Location search: Find cities worldwide, or enter latitude and longitude coordinates directly in the field. You can also use device location by hitting the GPS button.Seasonal presets: Quickly hop to solstices and equinoxesDate picker: Any date from past to future - perfect for seasonal comparisonsExport ready: Hit the Export CSV button to download the data as a CSV to load into another program. Or, hey, to stare at a CSV - your call.When you change the Location field, hit the Go button (or hit enter or return) to recompute.Understanding the dataFor the header in Table mode, you can hover (tap on mobile) for a tooltip explaining the field or calculations. Here's a glossary of what you'll see:Altitude is the sun's angle above the horizon (0° = horizon, 90° = directly overhead).Azimuth shows compass direction (0° = North, 180° = South). Shadow length uses the simple formula: object height ÷ tan(altitude angle).Shadow Length is the length of the shadow cast by the object you enter in the Height field.Phase indicators show you visual sunrise/sunset/twilight classifications with emojis, per hour in the day.Air Mass Factor indicates how much atmosphere sunlight travels through (lower numbers mean more direct light).In Visual mode, the sun's current position appears as a colored dot: yellow for day, blue for twilight, gray for night. The diagram includes subtle grid lines for elevation an...

Solar Cycle Progression - NOAA / NWS Space Weather Prediction Center
The observed and predicted Solar Cycle is depicted in Sunspot Number in the top graph and F10.7cm Radio Flux in the bottom graph. The predicted progression for the current solar cycle (Cycle 25) is given by the magenta line, with associated uncertainties shown by the shaded regions. This prediction is based on a nonlinear curve fit to the observed monthly values for the sunspot number and F10 ...
