Note:

 When DST is in affect the forecast station will need to receive the WWVB time signal to make the 

adjustment for DST. The WWVB signal includes an embedded bit to tell the station to adjust for DST. Until that 
signal is received the first time, the sunrise/sunset times will be one hour off. 
 

Tide 

 

The tides reflected on this station are based on the ebb and neap tides of the lunar month rather than the daily 
high and low tides.  When the sun, moon and earth are lined up at new and full phases of the moon, tides will be 
higher. When the moon is at right angles to the sun and Earth at the first and last quarter, the tides are weaker.

Moon Phase 

 
The LCD Moon phase is divided by 6 
sections, showing a total of 12 phases of 
the moon. 

Note:

 With the moon shown against a 

light colored background, the phases will 
show opposite to a paper calendar. The 
segments that are highlighted portray the 
part of the moon that is lit. For instance, 
the moon will be blank during a new 
moon and dark during a full moon. 
 

 

 

New Moon

 occurs when the moon is between the earth and sun so the illuminated portion of the moon is on 

the back side facing the sun and we cannot see it. After a new moon, the illuminated (visible) portion will 
increase or wax until the full moon occurs. 

 

Full Moon

 occurs when the earth, moon and sun are in approximate alignment, with the moon and the sun 

on opposite sides of the earth. The illuminated portion of the moon faces the earth, giving us complete 
visibility of one side of the entire moon. After a full moon, the illuminated portion will decrease or wane until 
the new moon occurs. 

 

First Quarter

 and 

Last Quarter

 moons occur when the moon is at a 90 degree angle to the earth and sun. 

So we see half of the moon illuminated and half is in shadow.  

 

Waxing

 means growing or expanding illumination and happens after a new moon. 

 

Waning

 means decreasing illumination and occurs after a full moon. 

 

Crescent

 refers to the moon being less than half illuminated. Crescents can be waning or waxing. 

 

Gibbous

 describes a moon phase when more than half is illuminated. Gibbous can be waxing or waning.
