While taking the trash out, I noticed that the moon was nearly full. Actually one day after the full moon. Since the sky was clear, I also set cameras up to do some star trails. There definitely are more jets flying than one and two years ago. Also a couple of meteor trails. A couple of notes using the Leica Q2 monochrome for composite star trail images. The ISO needs to be 100 and the exposure time no greater than 4 seconds, otherwise a second dark (shutter closed) image is taken and subtracted to remove sensor noise. Also, I wish the camera had an option to connect an external power source so I could take longer sequences.

While taking the recycling out last night I noticed a moon ring (22° halo) in the sky.

Time-lapse video of a day in the wildflower meadow. This section was plated late in summer with Cosmos and Plains Coreopsis. The earlier planting in this section failed, mainly coming up with tall grass instead of the spring to summer wildflowers. I mowed the grass down, rototilled, and covered with a black-agricultural fabric to kill off the weeds for several weeks before replanting. I am now starting to get some flowers even though the plants are not very tall. Another section was planted with Marigold and Zinnia. They are not growing very fast, and have not bloomed. It also doesn’t help that the Deer and Ground Hog continue to nibble on the small plants. [Click on the full screen button, bottom right corner to view a larger image.]

I haven’t seen any Monarch butterflies until today since August. Usually there are some of the group that migrates south to hibernate around in October. One of the places that I usually see them in October is at the Sourland Mountain Preserve. This year the brush along the high-pressure underground gas line was mowed, and there are no flowers to attract the Monarch butterflies. Today, while rototilling one of my wildflower meadows to prepare for next spring I noticed the shadow of a butterfly flying. When I turned around, I saw a Monarch. It landed on a Zinnia flower. I dropped everything and ran inside to get a camera. When I got back outside, I found the Monarch feeding on a Marigold flower.

Deer in the backyard. They keep trying to get into the fenced off areas. Some look pretty scrawny.
