Now is the winter of our discontent

Would you believe today is the first day of winter. If you're in the northern hemisphere, you might be thinking: "Do not be a fool Noah, the sun is shining. Summer is about to start." Those of you who know we're in New Zealand might be thinking something like: "One would think winter starts on June 21st...you fool." Hey, quit trying to spread your American Imperialist ideas down here. Winter starts today, and that's final. Also, I'm really cold.

In astronomical reckoning, the solstices and equinoxes ought to be the middle of the respective seasons, but, because of thermal lag, regions with a continental climate often consider these four dates to be the start of the seasons as in the diagram, with the cross-quarter days considered seasonal midpoints. The length of these seasons is not uniform because of the elliptical orbit of the earth and its different speeds along that orbit.

From the March equinox it takes 92.75 days until the June solstice, then 93.65 days until the September equinox, 89.85 days until the December solstice and finally 88.99 days until the March equinox. In Canada and the United States, the mass media consider the astronomical seasons "official" over all other reckonings, but no legal basis exists for this designation.

Because of the differences in the Northern and Southern Hemispheres, it is no longer considered appropriate to use the northern-seasonal designations for the astronomical quarter days. The modern convention for them is: March Equinox, June Solstice, September Equinox and December Solstice. The oceanic climate of the Southern Hemisphere produces a shorter temperature lag, so the start of each season is usually considered to be several weeks before the respective solstice or equinox in this hemisphere, in other countries with oceanic climates, and in cultures with Celtic roots.

And Jupiter aligns with Mars

View from our window this morning. Sorry it's a little out of focus...if anyone would like to send me a tripod that will support a rather heavy camera, I would be most grateful. This link tells me I'm looking at Mercury, Venus, Mars, and Jupiter.


In other news, visitor #3 (or possibly #5, depending on how you count) has recently returned home. We miss you Nam. For some reason, my camera did not like focusing on you...but here you are with some of the locals.


Here you are amongst some local colour.


And here you near the top of the world.


Here's Nico amongst the giants.


It rained a whole lot, so I did not have the camera with me very often...but we did manage to see a few new sights, including the National Wildlife Centre.

They had this neat parrot thing that I cannot remember the name of.


And an almost sunset.

Why I don't blog every day

[Because every post would look like this:]

It stopped raining, so I mowed the lawn. The lawn was really long because it had been raining all week. After I finished mowing the lawn, we took a walk to the Bluff Hill Lookout. When we first got to Napier, this was one of the first places we went; for some reason Nico had not been back since.

Here's Nico above the Port.


The Port is one of the few places in Napier that is open 24/7. Even on a Sunday night, you can watch timber being loaded onto giant ships. Apparently it goes to China, then we buy it back as furniture. [Note: I get told a lot to recycle paper to "save a tree". If you want to save a tree, stop sending all of them to China.]


Westshore and Ahuriri in the other direction.
