July’s full moon is now visible. Here’s what to look for : NPR

The third supermoon of 2022 will grace the night sky on Wednesday.

It's also known as a buck moon because it falls in July. The name doesn't come from its appearance — you won't see the shape of a buck on the moon's surface or anything. Instead, it refers to something that's happening in nature.

"The full Moon in July is called the Buck Moon because the antlers of male deer (bucks) are in full-growth mode at this time," as The Old Farmer's Almanac says. "Bucks shed and regrow their antlers each year, producing a larger and more impressive set as the years go by."

The Sundial Primer – Azimuthal or Azimuth Sundial

The azimuthal dial indicates the time by the sun's direction. The dial must be designed for a particular latitude. Figure 1 illustrates a dial that is designed to indicate Local Apparent Time (LAT). The hour lines appear as curved lines on the horizontal dial plate amongst the circular date lines. The gnomon is a vertical pin located at the centre of the dial. The dial must be positioned on a horizontal surface and orientated in the north-south direction as shown in the figure. The time is read by noting the hour line that the gnomon's shadow intersects for a particular day.

Remote Sensing as Art 🎨

Remote Sensing is the use of things like satellites 🛰 and aerial photography ✈ to take pictures of the land below. Nowadays with so much data easily available it’s wonderful not just from a scientific perspective but also to look at land and the patterns it represents from an artistic perspective.

In furtherance of artistic goals, I actually added a new feature to the internals of the blog, that allow me to modify the brightness, saturation, and color of any satellite image to make it look even prettier or capture a certain artistic effect on the blog live. 🎨

‘Wobble’ in moon to cause severe flooding in US coastal cities in 2030s – syracuse.com

The moon is currently in the “tide-amplifying part of its cycle,” according to NASA, but by mid-2030, when this intensified series returns, people living in coastal cities may be dealing with severe floods “every day or two.” Why? This natural yet amplified lunar cycle will be coupled with higher sea levels caused by global warming, triggering a decade of dramatic surges in the number of days with high-tide flooding on nearly all mainland coastlines in the U.S., Hawaii and Guam. High-tide flooding, also known as “nuisance” or “sunny day” floods, is projected to exceed thresholds across the nation more often and occur in clusters that last a month or longer, the NASA Sea Level Change Science Team of the University of Hawaii said. Their study was published last month in the journal Nature Climate Change.
