Solar Eclipse of August 21


   I too have written some information about the solar eclipse, aka “The Great American Eclipse”, of August 21st. It is my attempt to compare two different views of the eclipse. One will be from within the path of totality where I will be, and the other in my hometown of Lee’s Summit Missouri just south of the path of totality by a few miles. As a result residents in Lee’s Summit, unless they drive north, will only see a partial eclipse with 99.986% of the Sun covered.

2017 June Solstice

21june-ecliptic   Northern hemisphere spring comes to an end and its summer begins on Wednesday day June 21st at 4:24 UT (11:24 pm CDT Tuesday June 20th) when the Sun ‘reaches’ the celestial coordinates of 23.5o north declination and 6 hours right ascension. With respect to the Earth’s surface the Sun is described as over the Tropic of Cancer, 23.5o, north latitude of the Earth’s equator. At this same time the Sun is just entering the boundaries of the astrological constellation Cancer the Crab. Interestingly about 11 hours later, June 21st at 15 UT (10 am CDT) the Sun will actually be entering the region of the Gemini Twins as it crosses the boundary between Gemini and Taurus.
Just had to include this!!
   According to the pseudoscience of astrology the Sun, at this date, would be entering the astrological sign of Cancer the Crab.

   We know that it is the Earth’s orbital motion around the Sun that causes the sun’s apparent eastward motion among the stars in the background. This is how the Sun ‘reaches’ a celestial coordinate, how it ‘crosses’ the boundaries between constellations, or how it is ‘in’ a constellation.

   With respect to the southern hemisphere this is the end of their summer and start of their fall season. So thinking globally my preference has been to use the name of the month to designate the season change. Hence the use of the term June Solstice rather than summer solstice.

Saturn at 2017 Opposition

saturn-opposition-ani
   Thursday June 15th the outer planet Saturn reaches its orbital position known as opposition. This is a position which has the faster moving Earth passing Saturn and at opposition is centered between the outer planet and the Sun. Picture the arrangement with the Moon at full phase; Sun – Earth – Moon, and that is similar to the arrangement for Saturn at opposition.

   When an outer planet, like Saturn, reaches opposition that planet rises around local time for sunset and is visible all night.

ISS Followed the Arc

   Last evening, Sunday June 11th the ISS, International Space Station orbited over my part of the world. The ISS appeared about 45o above the west-northwest horizon and followed a path that went below the bowl of the Big Dipper and in a straight line ‘followed the arc to Arcturus’ in the constellation Bootes the Herdsman. At its peak the ISS reached nearly the zenith and at its brightest had to be at least -3.0 in apparent magnitude. After a several minutes the ISS moved out of sunlight and faded from view above the southeastern horizon.
Camera settings were 18mm; ISO 800; F4.0; 2 sec.
   One dependable and accurate source of viewing information for the ISS is at NASA’s ISS Sightings web site. Here you may learn the time and direction the ISS will appear, its duration of visibility, and its time and direction it will stop being visible.

   In a similar manner the Heavens Above web site will also provide viewing information for the ISS but in addition it will display a star map showing the path across the sky. This sample graphic shows the ISS path for June 12th.

   Want to see what the Earth looks like from the ISS? Click on this link to go to the ISS HD Earth Viewing web site for a view from one of several cameras mounted on the ISS as this screen capture shows. There are two additional maps that show the current position and orbital path of the ISS.

Neptune at Western Quadrature

orbital-positions   On Sunday June 4th the position of the planet Neptune with respect to the Earth and the Sun places this ringed planet at what is called western quadrature. At that orbital position Neptune, and actually any outer planet, is at a 90 degree angle from us as this graphic shows. Think third quarter Moon as that is a fair comparison of the relative positions. At this position Neptune leads the Sun across the sky from east to west as the Earth is rotating, meaning that Neptune rises before the Sun and also sets before the Sun.

click on graphic to see it larger   Neptune currently is within the boundaries of the constellation Aquarius the Water Bearer. At around 7th magnitude Neptune is too dim to see with the naked-eye but easily seen with a telescope or binoculars. In 7×50 binoculars Neptune may be visible near the 4th magnitude Lambda Aquarii, and just below the point of a small triangle arrangement of 6th magnitude stars.

   This is a short video clip from a much longer video that I made as part of a live musical performance called “Orbit” at the Gottleib Planetarium in Kansas City Missouri during May 2011.

Climate Change and Bees


   
So why the bee pictures? It’s all about climate change and the significance of these little residents that we share our planet with. A point is that climate change will certainly have an impact on the human population but perhaps even more serious will be the harm it does to Earth inhabitants like the Bee and its important work of pollinating plants.

   Here is an interesting an informative video from NASA about Bees, pollination, and how the Bees are used in a study about climate change effects..

   Keep informed about climate change with these smartphone apps from NASA.

Remember: Earth is our home, our only home.

Don’t Panic, It’s Only A Towel!


   Thursday May 25th, or any day that is May 25th we celebrate, in our own way, (yes we do) the Book,
Hitchhiker’s Guide to the Galaxy
, by Douglas Adams. What is the significance of the towel? Click on the graphic to enlarge it to a readable size to find out.
   So be a hoopy frood and click on this link to visit the Towel Day web site.

   Overheard on Jeopardy: “42.”
And the answer is: “What is the meaning of life?”
