Dear X-Air, Felix, and WeatherCat observers of the heavens,
So called SuperMoon tonight, Edouard.
I'm a bit puzzled by all this fuss over "Super Moons." That the Moon is around 10% larger doesn't seem very exciting to me and the additional brightness would only be of value for people trying to perform outdoor activities by moonlight. The phrase doesn't appear to be particularly old. When I first got into Astronomy many decades ago there wasn't a name for a full Moon at the perigee. Why this phrase came into common usage and why it is hyped up by using the adjective "super" ? . . . . . Well, I'll let the facts speak for themselves . . .
Of greater concern are the also hyped up "King tides."
https://en.wikipedia.org/wiki/King_tideBetween rising sea levels, deferred maintenance, and dubious building practices, these extra high tides are leading to flooding that harms people. We are having calm weather for this king tide and that appears to be the situation along every seaboard of the United States. So the tides today aren't likely to do much harm. However, there are two additional King tides in January. If the weather isn't so benign, there could be trouble in coastal regions.
Cheers, Edouard
