Total Lunar Eclipse Times

Written by The Night Sky Guy on December 9, 2011 – 6:14 pm -

Early Saturday morning, Dec.10th the last total eclipse of the Moon of 2011 and the last one until April 2014 will grace Earthly skies. All of western North America will have front row seats to the show as the Moon slips into Earth’s shadow and turns orange-red in colour. My advice is to get outside by 4:50 PST and look towards the western sky for a full moon and be patient as the partial eclipse gets underway and totality begins at 6:06 am PST- lasting a full 51 minutes.

Folks in Eastern Canada are out of luck this time as the moon will already have set below the horizon by the time the eclipse gets underway.

Check out my lunar eclipse story for National Geographic here – you will find a link to a LIVE telescope view of event too!

Here is a timetable for the lunar eclipse phases for different timezones (courtesy of Sky & Telescope magazine):

    Lessons from observing the lunar eclipse

    Here are four lessons I learned from getting up early this morning to view the lunar eclipse:

    Sloppy is okay
    Sleep is bad
    Don’t breathe
    Back up

    SLOPPY IS OKAY
    I got up at 4:30am MST to set up my telescope. I had it outside covered all night, but now I had to get it aligned and ready. I didn’t bother trying to center either of the two alignment stars, choosing to accept wherever the telescope pointed. That worked out fine. The telescope tracked the moon perfectly, at least for visual observing.

    SLEEP IS BAD
    I knew I wasn’t going to see any of the total eclipse. “Red Mountain Observatory” is a significant exaggeration of the term “observatory.” It’s just my telescope on wheels that I roll out to view. But Red Mountain is no figment of my imagination. It looms large in the west. As a result, I knew I would not see any of the totality. And I knew it was going to be cold, okay – cool (26 degrees f and 47% humidity). So I was considering sleeping through it.

    That would have been a mistake. I got to experience almost an hour of the eclipse, starting at about 5:49am when the earth’s shadow first hit the moon. Red Mountain didn’t interfere at all until 6:37am. Those 48 minutes at the telescope were well worth a little lost sleep. And, in a way, the best was yet to come. Between 6:37am and 6:40, when the moon slipped completely below the mountain, the view was stunning. I had not expected to enjoy seeing the mountain interfere with the eclipse, but it was amazing seeing the moon being rapidly swallowed by the rocky cliffs.

    DON’T BREATHE
    I was worried about dew, but thought it would not be much if any of a problem. Even so, I attached my dew shield and I wished I had ordered a heater months ago (I ordered a DewBuster from Ron Keating a few days ago, but it won’t be here for a few weeks). The end result was there was nothing to worry about. The telescope didn’t attract moisture. But my eyepiece did. I was spending a lot of time looking through it and either my body heat or breathe was fogging up the eyepiece and then freezing. It was easy to wipe off but it kept happening until I started holding my breathe whenever I was looking through the eyepiece. That worked.

    BACK UP
    I have not spent much time looking at the moon, and almost no time looking at the full moon. I knew my 40mm eyepiece had a wide enough field of view to take in the whole moon. But it didn’t have much more room than that. It would have been nice to frame the moon with a little more sky around it. If I could just back up five feet. Oh wait, that only works when taking family photos. So I need to look into either an eyepiece with a wider true field of view or a focal reducer.
