When you want to see the stars, find someplace dark
Exploring the cosmos
I missed the closest approach of Venus and Jupiter. Not for lack of trying. I had set up the telescope and camera in the driveway. A clear afternoon clouded over at sunset, leaving me only glimpses of the planets through a fleeting gap in the clouds. I had time to focus enough to see the crescent of Venus, which promptly faded from sight.
The next evening I am on the summit. No small telescope available, but I did have the camera to record a stunningly beautiful evening atop the mountain.
It has been over three months since the protest began. Three months of standoff with the protesters who would not see another telescope built on Mauna Kea.
It is with my handmade 18 inch telescope that I can truly gaze into the depths of space. This simple device of plywood and glass allows me to see galaxies millions of light years into the past. With this telescope I have seen hundreds of galaxies, giving me a glimpse of the indescribable vastness of space.
Often I would set up in the patio right at the Mauna Kea Visitor Information Station. The first couple hours spent talking with visitors, showing them the wonders our universe has to offer. After the VIS closes the visitors depart, driven back to their hotels by the cold mountain air. I have a heavy winter jacket, ski-pants, a thermos of hot tea, everything I need to be comfortable under the night sky. I would have the rest of the night to myself, just me, the mountain and the stars.
A reminder that this evening will see the close approach of Venus and Jupiter. Watching over the last week we have seen these two bright planets growing ever closer in the evening sky.
The closest approach will be about 0.3° tonight, June 30th at 16:14HST. They will be slightly further apart several hours later at sunset.
This is the best opportunity to see the pair at their closest for observer in Hawaiʻi. If you want to see the closest approach you can also try to observe the conjunction in the late afternoon sky. Both planets are bright enough to see in the daytime.
After this the pair will separate slowly and disappear into the sunset glow together.
At their closest the two will be easily close enough to bee seen together in the low power view of amateur telescopes. It makes a fascinating sight to see the two planets together in the eyepiece.
From all accounts it was a bit of crazy on the mountain today. I did not attempt to go up, even though I had originally been scheduled to do some training today for the summit crew. I have spoken with guys at HP and gotten fragmentary information here and there.
This is also the day I got called in to our HR manager’s office to discuss my blogging. It seems someone, who I will not name but is probably reading this, was not happy with my getting quoted on the BIVN website. Not that I gave David Corrigan the quote, he simply lifted it out of my Monday post about the ahu being constructed at the TMT site. Which is interesting as I was only noting the blindingly obvious fact that the protesters had assembled the ahu in the middle of the road as a dare to the construction crews. In response I simply noted that I had complied with observatory policy.
Today Mercury will be at maximum western elongation, as high in the morning sky as it will appear for this current apparition. After today the planet will slide back into the dawn, passing through superior conjunction on July 23rd to reappear in the evening sky in mid-August.
With the announcement the TMT will restart construction everything seems headed for a showdown on the mountain. The protesters are clearly preparing for action. The day is Wednesday. I was scheduled to do a training session for our crew this Wednesday, I have cancelled this. This sort of thing is common as the rest of the observatories consider how we will deal with a possible prolonged blockage of the road.
Dan confirms that the rocks were rounded boulders in mixed sizes. Rounded rock, as one would find in a stream bed, is particularly desirable in the building of a proper sacred structure such as an ahu or heiau. According to legend that the rock to build the great heiau at Puʻu Kohala was hauled all the way from Waipio Valley by a chain of men across the island.
Obviously they are daring the construction crews to dismantle the structure, then to be able to claim desecration when that happens. Whatever happens our crews will have a first hand view from our site overlooking the TMT site.
I hope for more updates as the situation evolves. With Wednesday cancelled I still hope to go up Friday to complete a few things, whether I do attempt to go up is a bit indeterminate at the moment. Will wait and see.
The dance of Jupiter and Venus continues in the evening sky. Over the next few days we will see the pair drawing closer. Currently an obvious pairing in the sky after sunset, the two are just 4.5° apart today. With Venus shining at -4.4 and Jupiter somewhat dimmer at magnitude -1.8 it is hard to miss the pair.
The closest approach will be about 0.3° on June 30th at 16:14HST. Thus the evening of June 30th will see the pair at their closest for observer in Hawaiʻi. If you want to see the closest approach you can also try to observe the conjunction in the late afternoon sky. Both planets are bright enough to see in the daytime.
After this the pair will separate slowly and disappear into the sunset glow together.
At their closest the two will be easily close enough to bee seen together in the low power view of amateur telescopes. It makes a fascinating sight to see the two planets together in the eyepiece.
