Carter was initially stationed in Norfolk, Virginia, where he served on the USS Pomfret and the USS K-1. In 1948, he was assigned to the USS Alabama, where he worked as an electronics officer. Carter was responsible for maintaining the ship's sonar and radar systems, which played a critical role in the ship's defense.

AD Leonis (Gliese 388) is a red dwarf star. It is located relatively near the Sun, at a distance of 16.2 light-years (5.0 parsecs), in the constellation Leo. AD Leonis is a main sequence star with a spectral classification of M3.5V. It is a flare star that undergoes random increases in luminosity.

HD 5501 (= BD+59 154 = BSD 8-397) is a 9th magnitude star in the constellation of Cassiopeia. It has recently been discovered to be an eclipsing binary with a period of 7.53 days with a primary eclipse of 0.45 magnitude and a secondary of 0.3 magnitude. The system is constantly varying suggesting an ellipsoidal variable with the stars in or near contact, perhaps with one or both Roche lobes filled. https://www.astro-richweb.net/astro/star_HD_5501.htm#HD_5501

All Sky 360 Nautical Twilight Image at Great Basin Observatory. First night in several weeks with everything working and clear skies. Tonight we focus on two flare stars, MG-1995959 and later this evening AE Leonis until morning.
First light with the Whoopshel Spectrometer at GBO. This is the spectrum of the star Vega. We will use this tool to detect the chemistry of exoplanet atmospheres. Imagine detecting chemical signatures of life in a faraway planet!
V1005 Orionis is a young flare star in the equatorial constellation of Orion. It has the identifier GJ 182 in the Gliese–Jahreiß catalogue; V1005 Ori is its variable star designation. This star is too faint to be visible to the naked eye, having a mean apparent visual magnitude of 10.1. It is located at a distance of 79.6 light years from the Sun and is drifting further away with a radial velocity of 19.2 km/s. The star is a possible member of the IC 2391 supercluster. Flare activity was first reported for this star by N. I. Shakhovskaya in 1974. B. W. Bopp found anomalously strong lithium lines in the spectrum of GJ 182, a rarity for stars of this class and a possible indicator of a very young star. Together with F. Espenak, in 1977 Bopp demonstrated the star showed periodic variations similar to BY Draconis. In 1984, Byrne and associates found a preliminary rotation period of 4.55 days and showed the star had a normal flare rate https://en.wikipedia.org/wiki/V1005_Orionis
Asteroid - 2001 BD 57 is a member of the Main Belt belt which is located between the orbits of Jupiter and Mars. At the time I captured it in August its magnitude was 17.5 and was fully illuminated. Captured at Great Basin Observatory with a CDK 700. Processed in Astroimage J.

At the center of this image lies WDS 01052+6105 STI, a suspected double star pair that will be measured by a student in class tomorrow. First measured in 1901 PA=152 and SEP = 11.2 it was last observed in 2015. There are more than 20 double star pairs in this image.

NGC 6914 - Shot last night so not enough data just yet, might be a bit over processed but it shows promise with a few more hours of data gathering. Next 4 nights are clear here, so going to go deep on this one. #astronomy #astrophotography

The flight of New Horizons is depicted here from its launch in 2006, across the solar system to reconnoiter Pluto and then the Kuiper Belt. The spacecraft is speeding so fast that it will leave the solar system and enter interstellar space in the 2030s — never to return. (Credit: NASA/Johns Hopkins APL/Southwest Research Institute)
