The air temperatures continue to raise overall, but they did stall during the third week. Since it was rainy during that time of the month, it was also more humid. From the 16th to the 27th, we got over two inches of rain. The ground continued to warm up to the benefit of plants.

Because of the threat of rain, the Amprobe TR200 Temperature and Humidity datalogger was left on the front porch. From the spike shown in the data, the sun must have shown on the sensor for a period of 40 minutes beginning

I left the Photometer in the shadow of the house to see how it would react. Now I know, it doesn't measure the brightness of the overhead sky, it measures it's direct exposure to sunlight.
|At 11:00 local time, the sun cleared the roof of the house.|

This is an early morning image, so the sun is rotated from my afternoon images. AR2740 is fading away and AR2741 is getting more prominent. Through my hydrogen alpha telescope, it appears AR2741 is two dark patches touching at their edges. I can also see a bright ring suurounding the sunspot and that ring looks like two intersecting rings.

The younger AR2741 is getting darker than AR2740. I was able to separate AR2741's outer, brighter rim (penumbra) from its inner, darker umbra in today's image. Based on the sun's pixel size and diameter in miles, I determined that AR2741's umbra has a diameter of 9,255 miles and it's penumbra has a diameter of 18,023 miles. Compare this to Earth with a diameter of 7,920 miles.

Sunspot AR2738 still exists and remains active. After the sun's rotation carried to the far side of the sun (from our perspective) for two weeks, it has reappeared. The sunspot is now called AR2740 and is visible in the upper left of the image I recorded this morning.
Odd blips in the data in the morning before sunrise up until noon. After sunset, all channels behaved normally.

Three temporary spikes of questionable air quality. However, for the week the air quality has been very good. The average air temperature dropped slightly during the middle of the week. However, we are now on a rebound with even higher temperatures expected.
