The chart shows Hurricane Wilma stationary over the Yukatan Peninsula on 22th Oct 2005.

With version 1.03, the declination (height above/below earth equator) can be displayed in the inner ring of the chart.

To achieve a nice display, the declination angle is displayed as cycle. Declining declinations are placed into the 2nd and 3rd quadrant of the inner circle. This way, the declination cycle goes almost hand in hand with the ecliptical longitude.

The scale of the declination circle displays the angle from -30 to +30 degree. The Moon, for example climbs up to 28.5 degree (with the Moon Node at 0 Aries), and will then jump directly into the next quadrant.

Examples of usage:

• It shows that hurricanes remain stationary at their latitude position, whenever the Moon is at her maximum northern or southern declination. Most often this is when the hurricane hits land. This makes the maximum declination of the Moon alone a good indicator for the time of the probable landgoing of a hurricane.
• Ecliptical Aspects between two planets are anhanced, if the declination of both planets meets at equal or opposite equatorial heights (declination). So, even an exact conjunction may still have a gap in the declination.
