Sunset Time Incorrect
« on: November 10, 2018, 04:56:59 PM »
I just noticed that the sunset time for my station page (https://www.wunderground.com/weather/us/pa/sadsburyville/KPAPARKE2) is two minutes or so late.  I wouldn't have noticed except that my wife looks at the same station data using the "old" version of the sation page (http://maps.wunderground.com/weather/us/pa/sadsburyville/KPAPARKE2?cm_ven=pwsdash_cityforecast) and the sunset time is two minutes earlier and is correct based on another site (https://sunrise-sunset.org/calendar).  The sunRISE time appears correct.

Has anyone else noticed this for their station page?

I see the same error. Hmmmm, I have no idea why that would be. I'll just call it a software bug.

I too see the same problem but it looks like the new WU page is the correct one. For me the new WU page matches my exact location according to this neat web map tool. Move the red marker to your location, then read results in box on the right.

Maybe the old WU page is not precise enough and is just going by a general area. Or the difference may be on how each site defines sunset. For example is sunset time reported when sunset starts or when the sun fully sets? So maybe neither are wrong, as one is reporting sunset start and the other is reporting when the sun sets completely.

Sun/moon rise/set times are based on the upper edge of the disc meeting the horizon.
