A visual solar-geometry playground
Look At The Sun (SAFELY)
Watch the Sun rise over the South Bay ridgeline.
A visual model of the Sun and the ridge—not a personal exposure assessment.

Where does the Sun clear the named skyline?
The ridge layers change with the selected date. This is a visual seasonal model, not a surveyed terrain obstruction calculation.

How haze changes a simple three-color direct-beam model
This is a transparent toy spectrum: relative direct-beam transmission at 450, 550, and 650 nm using air mass plus adjustable aerosol optical depth. It shows why the composition changes near the horizon; it is not a weather observation or a personal exposure calculation.
Method & sources
The Sun follows the NOAA solar-position approximation. The named peak anchors use public coordinates and elevations, then calculate their bearing and apparent elevation from a default Bay Area viewpoint. This is a summit-sightline model, not yet a full terrain DEM: an east-facing panorama from your actual spot is the next thing needed to make every ridge and gap pixel-accurate.
