Supermoon and Perseid Meteor Shower

August 10th, 2014 at 12:30 am by under Bill's Blog, Weather

supermoon    First check out this short video.  We’ve been enjoying the full moon this weekend.  The full moon of August is called the Sturgeon Moon.  This full moon is special, it’s  what’s called a “supermoon“.   The distance between the Earth and the Moon averages 238,855 miles.  However, because the moon’s orbit is an oval and not a perfect circle, that distance can vary from 221, 460 miles to 252, 700 miles.   Sometimes the full moon occurs when the moon is close to the earth and sometimes it occurs when the moon is farther away from the Earth.  The full moon on Sunday will be the closest full moon to Earth until 2034.  The exact time of full moon is 2:09 pm EDT (when it’ll be midday here and the moon will be shining on the other side of the Earth.   At that time Sunday, the moon will be approx. 221,765 miles from Earth.  This full moon will be approx. 14% bigger and 30% brighter than a full moon that occurs when the moon is farthest from Earth.  When the moon is closest to earth each month, that’s called perigee and when it’s farthest away, that’s called apogee.   The full moon is always in the opposite direction from the sun.  The sun sets now to the WNW, so look for the moon to rise Sunday evening in the ESE at around 8:37 pm.  The moon appears to look bigger at moonrise and moonset (it really isn’t) and it can have a yellowish or pinkish tint as the moon is shining through a larger layer of air.  We still have an occasional thin layer of smoke from wildfires in Canada and the Pacific NW that makes our sky look a little whitish during the day, instead of bright blue and can give the sun a yellow-orange appearance at sunrise and sunset.

The full moon will make it more difficult to see the best meteor show of the year, the Perseids, which peak in the early morning of August 11-13.   However, the Perseids usually produce a few bright meteors called “fireballs” and they should still be able to be seen despite the full moon.  Here’s this weeks Sky at a Glance.   The planets Venus and Jupiter can be seen in the early morning twilight in the eastern sky.  Mars and Saturn are to the SW shortly after sunset.  Look for the bright stars Vega, high overhead in the evening and Arcturus is to the west.  Vega will look white and Arcturus will look yellow or even yellow-orange.  Here’s when you can see the Intl. Space Station fly by.

Quick note on weather:  We are in the General T-storm Outlook for Monday – no severe weather is likely at this point.  The European model gives G.R. 0.34″ of rain for Monday/Monday night…the NAM has .05″ for Sun. night and 0.51″ for Monday PM and Monday night…the GFS-plot has 0.24″ Sun. night and 0.13″ Monday PM.   All three models have rain for pretty much all locations.  Also:  Parts of Kochi Prefecture in Shikoku, Japan have had 70-80 inches (1800+ mm) of rain in last 10 days (from Anthony Sagliani).

    I can see the smoke from the western Canadian fires from Alaska mountains. Pretty darn early here this morning as I’m use to getting up 5/6 in the morning and its 2:30 here now. I’m going back to bed anyway but very neat to hear the cry of the wolfs/coyotes out hear in the wild. My friends (I brought up here with us from Canada) and wife and I have really enjoyed the amazing scenery up here. The weather is fantastic and just a very quiet and beautiful state. Hope all is well back in the states haven’t even thought of Michigan. Have a good day. :)

      You have no idea how jealous we are of you. Hope you compile some highlight pics and share them with us. Enjoy and be safe (BEARS).

      Sounds awesome up there. Someday we really want to go there after the kids finish school and have moved out of the house.

  2. Nathan (Forest Hills) says:

    Another above average day here again. August is definitely a slow month for thunderstorms though… can’t wait for September.

    1. fixxxer says:

      Our storm chances are pretty low after july.

      1. Last year, I got over my average amount for September by Sept. 9

        As a matter of fact, the morning of September 9 I got 5″ of rain in 2 hours. My school was partly flooded as well as numerous roads (including a puddle as deep as halfway up you car door in front of my house!)

    87 my rear today.

  4. John drury says:

    Can anyone explain to me why we have been having an east wind for several days now, even though there have not been any storm systems in the area?

    1. Michael g (se GR) says:

      Clockwise flow around a high pressure centered to our north and east.

    Hoping for a good soaking here later tomorrow!

    1. Downtown has not got much rain since Mid July. Not sure what the exact total is but it is much needed in your area

  6. Its funny, on Fox 17′s interative rainfall total map it shows 10″ of rain for SE Michigan. Obviously that is overdone, but you get the gist some heavy rain is on the way.

    Downtown could use some rain along with lakeshore areas. Looks like the whole area will get rain tomorrow, NWS seems to side with 0.50″ for us here and 1″ for SE Michigan as of the earlier update, but it is still not clear yet as the GFS, Canadian GEM, NAM, and EMCWF are still all over the place where the deformation zone will set-up.

  7. John (Norton Shores) says:

    Of course the rain outlook from WPC has the lakeshore areas with the least rain over the next 7 days, with only about 1/4″ of rain in the next week. Meanwhile it has the rest of West Michigan getting between .5-1″ of rain, seriously what is it going to take to get rain in the lakeshore areas?

    1. Once you enter dry patterns its hard to get out it seems. You will get rain tomorrow without a doubt, so that’s at least good news instead of Sunny and Mid 80′s, right?

      1. John (Norton Shores) says:

        Indeed it’s very hard to get out of dry patterns, I sure hope we get at least some rain tomorrow. I will be happy with what ever we get, but could use a couple inches to really help ease this dry pattern. We need to get some rain before next weekend, because next weekend is looking like another warm and dry weekend.

          I came home from up north to water my parched plants. It helps to get native plants, but they need some rain. Forget the grass–it’s too late.

    Att nephew indy, either your ol uncle sparkee has smoked way to much pot this week or your MIA on the ol blog. I need you to bring some extra large baggies! Your ol aunty Edna used the last one I had to freeze fish.

  9. Jerry Hoag says:

    I am praying that I will be out of state before the first SNOWFLAKES fall here in West Michigan!!!!!!!! Also, Hopefully no snow in any of the areas that the wife and I will be visiting before the total move…….Here to the countdown to my BIG MOVE!!!!!!!!

    The Projected Date of leaving Michigan is November 3rd. Subject to change, to an earlier date.

    Will keep you all updated….

      I hope that get absolutely hammered with SNOW this winter!

    The beach at Holland was perfect today with a light breeze and refreshing water temps.

  11. Rocky (Rockford) says:

    The BEST SUMMER EVER lives on, except at fixxxers house! He had been whining and complaining all year long! What a life! Imagine that!

  12. Rocky (Rockford) says:

    I am ready for another polar vortex! Bring it!

  13. Sandy (Hudsonville) says:

    I was just out with the dog & the moon was shining thru some clouds. It was still pretty warm outside too. No breeze either. A very warm August night. We had a beautiful day today.
