11/27/2014 – Ephemeris – The voyage of the Mayflower

November 27, 2014 Comments off

Ephemeris for Thanksgiving Day, Thursday, November 27th.  The sun will rise at 7:54.  It’ll be up for 9 hours and 10 minutes, setting at 5:05.   The moon, 2 days before first quarter, will set at 10:51 this evening.

We are regaled with stories of the first Thanksgiving dinner between the Native Americans and the Pilgrims.  The Mayflower was headed for the Virginia Colony but were diverted by a storm.  Their first landfall in the New World was Newfoundland, where they picked up supplies.  Fulling intending to head south to Virginia, the passage became too hazardous, so they put into Cape Cod and there they stayed.  Back in those days the ship’s position was determined rather crudely.  Latitude was measured by the height of the north star and the sun at noon.  Distance and speed were measured with a log thrown overboard with a rope with knots in it.  The knots counted over a period of time gave the ship’s speed.

Times are for the Traverse City/Interlochen area of Michigan.  They may be different for your location.

Ephemeris for Tuesday, November 26th.  The sun will rise at 7:53.  It’ll be up for 9 hours and 12 minutes, setting at 5:05.   The moon, 1 day past last quarter, will rise at 1:42 tomorrow morning.

Comet ISON is now invisible from the earth, being too close to the direction of the sun to be seen.  However it is and will be in view of NASA’s fleet of solar observation spacecraft at least until the end of the month.  The comet is already in view of the STEREO Ahead spacecraft, looking back toward the Earth and Mercury.  Later tonight of early tomorrow it will be in the view of the Solar and Heliospheric Observatory or SOHO parked a million miles sun-ward from the earth.  It will appear on the LASCO C3 imager first.  Thursday it will also be visible to the Solar Dynamics Observatory or SDO.  On the Internet go to spaceweather.com at the page bottom click on STEREO, then click on Latest Images, or go to bobmoler.wordpress.com.
