Item 163: Lunar eclipse November 8

Entered by wh on Sun Nov 9 00:07:25 2003:

There is a total lunar eclipse this evening from about 800 to 830 pm 
EST. The moon is already about half covered.

Souther Lower Michigan is clear enought to see it! 
37 responses total.

Wow!  Read this item just in the nick of time.  Eclipse clearly
visible here.  Thanks, Bill.

Doesn't look like it'll be total, though.  One edge stayed uncovered, and it
looks like the moon is coming out of the eclipse now.

I missed totality, saw near totality and a few other points from 
Maryland.

I had forgotten about this until I was driving earlier this evening
and saw the moon looking odd.  I knew there was a full moon recently,
so seeing it darkened on the left side was wrong; the moon wanes from
the right.  Plus, the shape of the shadow was wrong.


#5 of 37 by jep on Sun Nov 9 05:08:58 2003:

I'd forgotten about it until the football game I was watching showed 
it.  I sat outside for about 45 minutes, watching the shadow cover 
most of the Moon.  It got pretty cold but I enjoyed it.

I then got out my telescope, but I'm not very good at using it, and 
didn't see much through it.

It is a total eclipse geometrically, but not total in terms of
illumination, as refraction of light by the earth's atmosphere
still illuminates the moon. 


#7 of 37 by gelinas on Sun Nov 9 05:51:24 2003:

I dunno; there was a sliver along the eastern edge (the bottom, looking east)
that was still reflecting the Sun's light, not the Earth's.


#8 of 37 by rcurl on Sun Nov 9 06:01:02 2003:

I should have written that it *cold* be a total eclipse geometrically
but not for illumination. I think the earth is big enough that the 
umbra of the earth can totally cover the moon. I'm not sure, however,
how much light would still reach the moon by *diffraction* around the
earth even if the earth had no atmosphere. 


#9 of 37 by sj2 on Sun Nov 9 06:02:13 2003:

Any copper/red moon viewings??


#10 of 37 by gelinas on Sun Nov 9 06:02:54 2003:

Yes, a total eclipse is possible; I've seen them before.  Just not tonight.


#11 of 37 by remmers on Sun Nov 9 16:36:08 2003:

Re #9:  The moon looked distinctly red when I viewed it during the
eclipse.


#12 of 37 by jep on Sun Nov 9 17:33:23 2003:

How often do lunar eclipses happen?


#13 of 37 by jep on Sun Nov 9 17:34:06 2003:

Also, do lunar eclipses always occur during a full moon?


#14 of 37 by gelinas on Sun Nov 9 18:02:16 2003:

I, too, saw the Moon as red during the eclipse.

Yes, lunar ecplises can only occur when the Moon is full.  Just as solar
eclipses can only occur when the Moon is new.


#15 of 37 by rcurl on Sun Nov 9 18:13:03 2003:

I saw an observation that the color of the moon during a total lunar
eclipse depends on the amount of dust and clouds in the earth's
atmosphere, so it is the refraction in the earth's atmosphere that is
responsible for the moon's illumination. 



#16 of 37 by bru on Sun Nov 9 19:26:49 2003:

they happen about twice a year.


#17 of 37 by slynne on Mon Nov 10 00:05:58 2003:

I saw it as it was almost finished as I was leaving the movies. It was 
cool. 


#18 of 37 by naftee on Mon Nov 10 01:21:08 2003:

I missed it, and I saw its beginnings.  Darn.


#19 of 37 by sno on Mon Nov 10 01:30:36 2003:

I didn't know about this, but when I was in the car and the moon 
started with a small chunk out of the upper left corner I got very
suspicious.  Checking space.com confirmed the event much to my 
absolute joy.  It was great.



#20 of 37 by other on Mon Nov 10 05:14:29 2003:

Saw it just beginning as I went in for the John McCutcheon concert 
in Royal Oak, and caught near totality for a moment during the 
intermission, which McCutcheon claimed to have timed specifically so 
we could catch it.  I cynically suspect he was merely taking good-
natured advantage of fortuitous timing.


#21 of 37 by anderyn on Mon Nov 10 14:58:34 2003:

We managed to watch it, and took out the binoculars/telescope to do so better.
The neighbor kids all came out and watched with us. It was very fun.


#22 of 37 by djf on Tue Nov 11 20:50:34 2003:

For those curious what the eclipse looked like, I took some pictures
as the eclipse progressed over Grand Traverse Bay, MI and created a
collage.  The coppery tinge of the eclipsed moon is clearly visible.

You can see the collage at:

There are 800x600 and 1600x1200 versions.  You are welcome to use the
images for your own personal computer background if you like, but any
other use, display, distribution, etc. is prohibited.  Thanks and
enjoy...

Is it possible to purchase a print from you? That is breath taking.  
Augusta, GA was severely overcast, and we didn't even get to see a 
twinkle of a star that night.

Awesome photos, djf!  Thanks for sharing!


#26 of 37 by slynne on Tue Nov 11 22:52:26 2003:

Wow, those photos are great!


#27 of 37 by aruba on Wed Nov 12 00:00:21 2003:

djf - can you tell us about how you took those pictures?  I have a digital
camera, and would love to learn to take stuff like that, but I have no
training in photography.


#28 of 37 by bhoward on Wed Nov 12 00:16:59 2003:

Wow.  Nice photographs, David.

What kind of camera, lense and settings did you use?  


#29 of 37 by mcnally on Wed Nov 12 02:07:26 2003:

  Very nice..  Great editing job.


#30 of 37 by jaklumen on Wed Nov 12 03:47:33 2003:

Sweet.

Thanks very much for the positive feedback.

I had been disappointed by the overcast conditions here during
the geomagnetic storms of the last few weeks.  But the sky
cleared after an afternoon of rain only minutes before the
eclipse started and I had my tripod ready...

The base images were taken with an Olympus CM-2100.  This is a
2.1-megapixel digital camera with a non-exchangable 10x
optical zoom lens.  While the raw resolution is not that high,
the powerful optical zoom and LCD viewfinder make it possible
to flexibly and accurately frame images, avoiding excessive
cropping after the fact.  This camera was discontinued a year
or two ago, but Olympus has continued the line with
increasingly compact designs, higher resolutions, and lower
prices -- a similar current model being the C-750.

The background photo of branches silhouetted on moonlit water was
taken at F2.8, 0.5 seconds, ISO400 and around 5x optical zoom.  This
is a 35mm film focal length equivalent of around 250-300mm, I think.
The moon "close-ups" were taken at F8, 0.5-6.0 seconds, ISO100, 10x
optical+2.7x digital zoom (~1200-1350mm).  The exposure times were
varied to account for changing light and sky conditions.

The raw images were edited and combined using the GNU Image
Manipulation Program (www.gimp.org) under Linux.

I did not intend to use this venue in a commercial way,
however if people are interested in prints I can investigate
the matter.  Please contact me via email.

kewl shots .. i also use the 2100 .. amazing camera for digital stuff

Ditto all the kudos.  If you are so inclined, "enter it in a contest", or
consider investigating publishing in a magazine.


#35 of 37 by jep on Wed Nov 12 22:36:04 2003:

I enjoyed the pictures as well.  So did my 7 year old.  Very nice job!


#36 of 37 by willcome on Thu Nov 27 09:34:47 2003:

I like pictures of whores.

unfortunately, I was stuck in a theatre in Pittsburgh that night.  I was stuck
in a certain theatre in Pittsburgh a lot of nights in November. . .
