The "Lowly" Thistle?

Late August presents all sort of weeds that might work equally well in a flower bed. This thistle, when viewed up close, has petals as delicate as threads and in a lovely shade of lavendar.

I wonder how we came to call this a weed? I suppose the fact that it survived the drought and managed unattended while the exotics died even when given their daily drink made all the difference. This thistle will sport some thorns later and the plant itself is spindly and lank. But think of the orchid! That something this beautiful can bloom in some hidden corner of the field, without cultivation, without fertilizer, without regular watering, makes it all the more special to me.

Watching the ISS Pass Overhead

Though this late evening image seems not to have captured the International Space Station passing overhead, it was a fairly bright pass just the same. I went into the back yard just before 9 p.m. when the sky still had a faint glow from sunset to it and waited for the 9:01 p.m. pass to begin. The ISS pass began in the WNW and ended about six minutes later in the SSE. When the station passed across the southern sky, it moved just below the moon and Jupiter.

The moon, by the way, was brilliant even though just past first quarter. I set the camera to telephoto (3x) and shot this picture on a tripod. You can see a little jaggedness to the left edge of the moon where the terminator slices through the lunar rugged terrain.

Besides the moon, Jupiter and the ISS, the backyard air was full of bats! Not one but probably dozens, all flying about for summertime bugs. If you listen in the still night air, you can hear an occasional "click" as they echolocate their next meal. A few night ago in the early evening I saw what I thought to be multiple small birds flying a circuit over our garden. What? Swallows? Martins? I walked outside in my bathrobe to see what it could be. I was met by hundreds of very large dragonflys! Other than a recent rain, there are no areas of standing water nearby - save our very small birdbath. It was magical.

All of this just proves how nice it is to spend some time outdoors at night. The country is especially pleasant at later hours when we can enjoy what the sky has to offer.

The Summer Heat

So far this summer, we've had 18 days at 90 degrees or above. Here's a graph of August so far.

Last evening (08/09) we had beautiful cloud formations as a cold front passed. Though torrential rains were reported well north and east of here, we had not a drop at my location. This view (below) is facing east through the catalpa trees in our front yard. A classic cumulonimbus!

And this view (below) is facing west as the final line of storms approached. To the right of the picture (north), it's clear that someone is getting some much-needed rain. But so far this month, Farmersville stands at 0.05". That's really critically dry, especially considering the extreme heat.

Is It HOT Enough Yet?

This summer has been one of the hottest I've recorded. Here in early August, I've logged 18 days with highs of 90 or above. Yesterday my "official" high was 98.7 degrees (with the electronic station) but a mere twenty feet away, also on the north side of the house, the bimetalic thermometer read an even 100 degrees.

Now that's in the shade, of course, and on the north side of the house. Coupled with the heat, we've had only 0.05" of rain in the last 12 days so the crops are beginning to feel the pinch. The corn is curling up trying to protect itself from this heat.

August has been well above normal; yesterday alone was 13 degrees above normal

It makes me wish for winter even more.

Welcome To Pinehaven

As an avid weather buff - I've been collecting meteorlogical statistics since April 1, 1974 and haven't missed a day. I was an early adopter of electronic weather stations. My first was a homemade Heathkit (I'm also an amateur radio hobbyist, WB8VQD) which I built in about 1980. Then I bought an early Davis station and finally an Oregon Scientific which I used for a few years. I eventually sold both and upgraded to a newer station, a LaCrosse.

I have two of these display units. One I have mounted in my bedroom so I can keep constant watch on the weather around the clock. The other is mounted on the living room wall for more casual (though still constant) use. All of the stats are collected on an electronic datalogger every 5 minutes. These figures are stored on CD's.

The unit shown is the electronic rain guage (top) and the anemometer/wind direction unit on the bottom. They're solar-powered and are attached to a post placed at the edge of our garden, about 100' away from the house. Readings are returned via a wireless link.

Above is the electronic outdoor thermometer/hygrometer. It's mounted on the north side of the house, protected from direct sunlight. Another similar unit, though battery-powered, collects indoor temperature/humidity readings.

Though I enjoy an electronic station, my "official" rainfall readings are taken with a standard NWS 20" gauge. I supply precipitation figures for Farmersville to the Miami Conservancy District.

The guage is mounted in the driveway and protected from blow-over by several concrete blocks. It's away from any obstructions which might alter a true reading.

Our property is amidst flat farmland and just to the east of Farmersville (this shot is facing east). Our barn is the white speck to the right of center in this shot. It's the perfect place to observe the weather with plenty of wide-open sky. Here's a map of where my station is located:
