Shadow on Shadow

I had a plan for this eclipse.

Partially eclipsed Moon rising above the shadow of Mauna Kea
A partially eclipsed Moon rises just above the shadow of Mauna Kea on January 20th, 2019.

I needed a quiet day to work on some code in the Keck 2 dome control PLC. One problem, every time I load code the dome lights go out. Guys working in the dome tend to object to the lights going out randomly.

Answer? Go up on a weekend when there as only a couple guys on duty and not a lot of work going on. I can have the whole telescope and dome to myself most of the day.

There is also a total lunar eclipse.

Many references state that the eclipse will occur on January 21st, and it will, in time zones further east than us here in Hawaii. We are ten hours behind UT, thus it will be the evening of the 20th when the eclipse occurs in the islands.

Witnessing a Total Solar Eclipse

By the time this is posted, by the time you read this, the eclipse will be long over. You will have been flooded by images and descriptions of this event from thousands of sources. However, this blog is a personal diary, I will put down my thoughts and memories before they grow dim, post my photos, and preserve the experience for myself.

Our plan was simple, camp out well ahead of time in a site that had been carefully selected and scouted. Jody and Larry camped along side this little pretty meadow earlier in the summer, noting that it would serve quite well. They also arrived first, five days before the eclipse, and minutes ahead of others that sought this same place.

The plan worked, and worked well. In the days leading up to the eclipse dozens of vehicles came past, each looking with envy at those who had arrived early to claim the best spots. The stream of vehicles continued late into Sunday eve, no matter, this forest offers room for all.
