It is the first day of fall (by some, but not all, reckonings; see June 25, 2013) and the weather shows it.  It was rainy and blustery last night, cool and damp this morning.  The frogs, apparently in denial, still swim around the pool but with grimaces on their faces.  The water is cold.  It has been too cold for me lately, too.

There are many, many cherry tomatoes on the Sungold and Black Cherry vines, most of them green.  And most of them have been falling off with each raw gust of wind.  The Sungolds in particular do not enjoy this cooler weather.  Even the tomatoes that turn the characteristic brilliant shade of yellow are about half the diameter of their peak-season counterparts.

In fact, I’m a bit worried about the Sungold vines.  They seem to be infected with some type of disease.  First the leaves, then the stems, and finally the tomatoes themselves turn a sickly shade of brown.  It is an eerie effect, not unlike the moon eclipsing the sun and casting the daytime world into a gloomy twilight.  Unfortunately, it is not a condition that is likely to pass as quickly (or at all).

I’m beginning to think that the Perseid meteor shower is nothing but a hoax, an elaborate practical joke pulled off by astronomers to keep all of us awake all night.

Based on the promise of as many as 90 shooting stars per hour, Rachel and I stayed up well past our bedtime tonight to see if we could catch a few of them.  The viewing conditions were good, for a change:  no moon and only the occasional wisp of a cloud (there was complete cloud cover during last night’s peak).  In fact, the night was unusually ideal with warm temperatures, low humidity and—blissfully—very few insects.

But there were also very few meteors.

Part of the problem for us is that we have a limited view of the night sky.  We live in the woods and there is only a small clearing where the house, pool and garden are located.  The surrounding trees are very tall and their height is accentuated by a rise in grade to the north of our house.  Consequently, lying on a hammock by the pool, we were gazing upwards almost as if at the bottom of a pit or opaque bowl.

A further complication is that we live only 60 miles or so from New York City.  It may seem like a great distance—over an hour’s travel by car—but at faster than 186,000 miles per second, the millions of lumens produced by the city’s buildings, billboards and streetlamps arrive in an instant.  There is little to obstruct the rays and a high concentration of particles in the air to diffuse them.  As a result, our southern sky is constantly aglow, even on moonless nights.

Yet another problem is that we are not night owls.  Staying up late is difficult enough but getting up in the middle of the night is next to impossible.  In previous years, I’ve set an alarm for 3:00 am or thereabouts, the time at which the constellation Perseus (from which the meteors appear to originate) is overhead.  But often it is chilly at that hour.  And even when I have roused myself and made my way outdoors, I have never really awakened sufficiently to appreciate what I was seeing.

Instead, we settle for late-night viewing, after 10:00 pm until around midnight.  At this hour, Perseus is still low in the northeastern sky, behind a high screen of maple trees.  Therefore, we miss (I presume) the bulk of the meteor shower.  I always imagine that a fireworks-like display of shooting stars is whooshing this way and that (yes, I know that meteors are actually silent) as we strain our eyes in vain, the scene obscured from our sight by the dense foliage.  Or maybe there is nothing there.

So, we didn’t get the lightshow we were hoping for; in an hour and a half of viewing, we caught sight of two satellites and a grand total of four meteors (to be fair, they followed the long, slow trajectory for which the Perseids are famous).  On the other hand, we did get a pleasant evening together outdoors, in the sweet summer air, listening to the comforting background music of the crickets and cicadas.
