I haven’t done any night sky images recently. It is getting colder, and the sky was clear with the Waxing Crescent Moon (nearly 3rd Quarter) shining brightly.

Daily Electric Energy Used (77.4 kWh) from Sense and Daily Solar Electric Energy Produced (34.3 kWh) from SolSystems and Locus Energy. The sun was out, but much colder outside. Overall a net deficit of 43.1 kWh. Geothermal HVAC was on to heat the house (11.9 kWh). Monthly server backups completed.
Weekly Electric Energy Used (444 kWh) from Sense and Daily Solar Electric Energy Produced (134 kWh) from SolSystems and Locus Energy. Overall a net deficit of 310 kWh. Cooler out so the Geothermal HVAC was on to heat the house. Notice the 12 hours when the power was off.
I am a scientist by training (Eckerd College, BSc; Caltech, Ph.D.). I worked for 27 years as a Chemist in the Pharmaceutical Industry developing processes to manufacture medicines for human and animal health. I now spend my time as a photographer and world traveler. My interests include the natural world, wildlife, landscapes, sky, and seascapes, travel, and astrophotography. I look for unique ways of viewing the world and presenting my images. I have traveled to over 55 countries in six continents, often on Semester at Sea voyages. While at home in New Jersey, I spend time on home renovation and expansion of a wildflower garden/meadow.
