Nine-Years Ago Today. Frost covered Common Barberry. Hobler Park, New Jersey. (06-Dec-2015).

Jet Silhouettes Transiting the Sun.

In addition to the sunspots (we are at or near the solar maximum) I captured two jets transiting the sun using a Vespera Pro telescope fitted with a solar filter.

Comet C/2023 A3 (Tsuchinshan–ATLAS)

The comet is getting fainter and the tail shorter. The magnitude is now 10.0. The first image is a composite of 31 images (5 min 10 sec) and the second one is a composite of 90 images (15 min). In the second image there is some movement of the comet head. Also, the comet is moving into a region of the sky with part of the milky way in the background (many more faint stars).

Jets and birds passing in front of the sun with sunspots.

The sky started out clear and sunny with clouds coming in later in the day. The Stellina telescope was fitted with a solar filter and set to observe the sun and sunspots. While reviewing a time-lapse video of the 18500 images (7h 45m compressed down to 10m 15s) I noticed the silhouette of a couple of jets and a bird (Turkey Vulture). Let me know if you see anything else (other than clouds) passing in front of the sun. It was windy with leaves falling from the trees. Even though it is Halloween, I didn’t catch a silhouette of a witch on a broom flying past the sun. By evening, the sky clouded over, so no images of the comet or other night sky objects.

Wintertime Nature in New Jersey.

Time-lapse video of yardwork on Red Rover. I needed to prepare for a storm predicted for tomorrow. Rain, snow, heavy wind, and temperatures dropping well below zero. The bulbs in Soft Pots that started to sprout needed to be brought back into the garage. Also, the Garden Shed that I had been storing the tractor implements blew over during the last windstorm. I was able to set it back up, but two of the ground anchors failed. For this upcoming storm, I decided to anchor the shed from within using a pallet of fertilizer.

Daily Electric Energy Used (81.8 kWh) from Sense. Daily Solar Electric Energy Produced (58.5 kWh) from Sense. Sunny. Deficit of 23.8 kWh. I should note that the Solar monitoring from SolSystem via Locus Energy stopped working since the Locus LG-120 meter uses 3G cellular to connect. ATT has turned off 3G cellular.


I’ve re-added the feed from my Ambient Weather Station.

Time-lapse videos: Day 3 of the Bok Choi seeds sprouting. Both videos are of images taken every 1 minute for 5 hours 45 minutes then displayed at 12 frames/second. I cut some of the paper retaining ring to get better visibility of the seedlings growing. During the second video, an invasive Asian Ladybeetle (Harmonia axyridis) and an invasive Brown Marmorated Stink Bug (Halyomorpha halys) were caught crawling by the Bok Choi seedling.
