Radio clock analogue display showing times of solar and lunar events

摘要

The clock has a conventional dial with hour, minute and perhaps seconds hands with additional display elements for presenting the rising and setting times of the Sun and Moon and time of max. elevation of the Sun from received radio signals. The additional electronic display elements are marks or digits predominantly in fixed spatial or temporal relation to the hour and minute symbols. Sunrise (a), sun highest position (c) and sunset (b) are indicated in red on an inner ring. Moonrise (d) and moonset (e) are indicted in blue in an outer ring, and the phase of the Moon (f) is an inset.
