Solar Eclipse | Protect Your Eyes

The first time I viewed a total solar eclipse was in 1999. We traveled to London, took the trains to Edinburgh, Glasgow, then Oban. Rode the ferry to the island of Barra for a few days. We came back to London and then to Dover for a couple of days. We boarded the high speed train to Paris. It went through the Chunnel and emerged in France going 185 mph. Another train from Paris got us to Stuttgart Germany in time for the total eclipse.

You need to have proper eye protection leading up to and following the total eclipse on August 21 in the United States. During the minute or two of totality, it is ok to view without eye protection. But, not before or after. Inexpensive viewers are available from many sources. Talk to a person from your local astronomy club. They will be happy to help.

Strawberry Moon | Micromoon | 9 Jun 2017

Moonrise for me last evening was 8:42 pm. I went out at 9:10 to see if the sky to the east was clear giving a view. Saturn was supposed to be positioned close to the right of the Moon. It was very hazy. The Moon was not bright and Saturn was not visible to me. I went back in the house for the camera and tripod. These two photos are at 9:20 and 9:21 with the Moon framed by some trees low to the horizon.

I went back inside to wait for the Moon to rise above some of the haze. When I returned at 9:59, the conditions were better. There was still a hazy glow near the Moon. I liked the effect. How about you?

9:59 pm CDT

Timing is everything, so I’ve heard. This moon coincides with the ripening of strawberries. Hence the name Strawberry Moon.

Much has been written in recent years about super-moons. That occurs when the Moon is at its nearest distance from Earth at full moon. This time, the Moon was at its farthest from Earth when full. The term mini-moon or micro-moon has been applied by some for this event. For more information about this full-moon, follow this link to Space.com. The following image compares a super to a micro moon. See this link for details.

Venus | Morning View | 24 Mar 2017

I got my first morning view of Venus this spring at 6:45. There was a layer of high clouds to the east dimming the view quite a lot. Binoculars helped locate it for a photograph. Thanks to Scott at Scott’s Sky Watch for pointing out Venus is now visible both in the evening and the morning if the sky is clear enough. He called it a double dose of Venus.

Looking slightly north of east through high clouds.

Clouds made the image a little hazy.

There was another bonus this morning. Looking to the southeast, the waning crescent Moon shined through a clear break in the clouds.

Occultation | Aldebaran Hidden Again

Once more, the Moon occulted the bright star Aldebaran in the constellation Taurus. Previous three posts are found here describing earlier occultations. I stepped out early to see if the sky was clear and got this image at 9:24 pm CST. My phone said the occultation occurred a few seconds past 9:52.

Aldebaran disappeared from view about 6 seconds into the video. I looked again at 10:33 pm and saw it had reemerged into view at the upper right of the Moon.

 

Earlier in the evening at 6:38 pm, I captured this slim crescent of Venus. It will quickly descend toward the Sun during the next two weeks and show a thinner crescent. On about 25 March, it will be aligned with the Sun and not in view. Early in April, it will emerge as a thin crescent before dawn.

Moon | Diffraction Grating View

I headed home after attending the public lecture on aurorae by University of Iowa professor Craig Kletzing. One part of his talk included a demo of color emissions from the element oxygen. It is responsible for nearly all the colors associated with aurorae. We needed diffraction grating glasses to see the demo effect such as these.

As I drove home, I noticed the bright crescent Moon. I stopped the car to look through my grating glasses. Once home I set up the camera with the grating over the lens. It was a nice way to end the day.
