Verna took this photo of the moon and Jupiter this evening. Although the pair are not as close as last month’s Lunar/Jovian conjunction, they are within a few degrees of each other. Click on the image to enlarge.

Helene – A Trojan Moon of Saturn in 3D
APOD published this nice image of Helene, one of Saturn’s Trojan Moons. The moon does not orbit the planet, but rather orbits ahead of the planet at one of the Lagrange points leading Saturn in orbit. Both Jupiter and Saturn are known to have these Trojan moons.
Of course, you will need your free pair of 3D glasses to view the anaglyph image. Click on the image to enlarge.

What a Difference Six Months Makes
A few years ago, I wrote the code for a sidebar widget that prints the solar ephemerides (daybreak, sunrise, transit, sunset, nightfall and the length of daylight hours) out on our website. Since yesterday was the shortest day of the year, I wondered how the data compare for the longest day of the year.
I took a screenshot of yesterday’s data and saved it as an image. Then, I monkeyed with my code to make the widget think it is June, 21, 2013, the longest day of the coming year. I got a screenshot of that data and merged it with the shortest day into the image above. The length of the day changes from just under ten hours to almost fourteen and a half hours – a net delta of 4 hours and 32 minutes.
We like our mild winters here but we love the summertime even more. We like the heat and the absence of the snowbird population that clogs the roads and supermarket aisles in the wintertime.
Scorpion Glow
I apologize for posting this out-of-focus picture of a dead scorpion on the RV drive, but the lighting conditions weren’t too good to avoid a slight camera motion that blurred the image. At any rate, I just wanted to show how these little beasties show up if you put ultraviolet light (a.k.a. black light) on them.

A while back, we bought little hand held flash lights with UV LEDs just for the purpose of detecting scorpions. Cabela found this one on the patio (thank goodness it was already dead) and I found a couple in the garage the other night using the UV flashlight.
Sunspots
After looking at the SpaceWeather.com website this morning, I want to the courtyard and took several images of the sun. There are three large sunspots visible in this image and several smaller ones that can’t be seen because of my my crude method of solar photography.
These three spots are not currently flaring, but they are capable of producing flares that hurl particles and radiation into space. If the flare comes toward Earth, it could affect power grids and communications.

Guns3
The FLASH™ tool I use came out with a new component; it’s a 3D photo cube. Move the mouse cursor over or near the cube to start it spinning. The position of the mouse cursor influences the speed and direction of spin.
I collected a few of the gun pictures previously seen on the other blog and loaded them into the parameters list for the cube object. It was surprisingly easy to use and I had the animation going in just a few minutes.
