For example, a measurement given as 12.14 +/- 0.01 cm is more precise than one given as 12 +/- 1 cm. Higher precision does not necessarily imply higher accuracy. Statistical (random) Uncertainty: This is the inescapable fact that every time you repeat a measurement, you will get a slightly different value.
The earliest sunrise of the month at Athens Eleftherios Venizelos International Airport is 6:01 AM on June 13 and the latest sunrise is 4 minutes later at 6:04 AM on June 30. The earliest sunset is 8:40 PM on June 1 and the latest sunset is 10 minutes later at 8:50 PM on June 28.
By the way, a similar situation occurs at the summer solstice, for the same basic reason, though the effect is not as extreme. Solstice occurs around June 21, but at latitude 40Â° north the earliest sunrise occurs around June 14 and the latest sunset occurs around June 28.
