About this deal

The paper is organized as follows. Section 2 describes the theoretical framework in asteroid lightcurve inversion. Particular attention is paid to the different surface scattering models utilized in the forward and inverse problems. In Sect. 3, error models are presented for dense and sparse lightcurves (relative or absolute), and the retrieval of absolute magnitudes and phase functions is outlined. Section 4 first provides the application of the methods to ∼500 asteroids with both sparse absolute Gaia photometry and dense relative ground-based photometry. Thereafter, a numerical forward simulation of dense absolute photometry with a Gaussian-random-sphere asteroid model (GS-asteroid) is described, followed by inversion results and their discussion. Conclusions and future prospects are offered in Sect. 5. 2 Lightcurve Inversion 2.1 Asteroid Modeling

Eros represents objectification, passion and desire, the thrill of the chase, and creative power. In the birth chart, this asteroid can point to areas where we pour a lot of heart, passion, and enthusiasm. Ceres is a dwarf planet and rules food, agriculture, transitions in a female’s life, nurturing, motherhood, and family relationships. With Ceres, there is a love of what is simple, natural, and good for you. There is also a strong need to nurture and protect, as well as to treat other living beings, including animals, with respect. INFORMATION TO CORRECTLY UNDERSTAND EPHEMERIS LIMITATIONS AND UNCERTAINTIES. SPK File Generation Introduction The Planets & Asteroids Ephemeris includes the major planets, North Node, Chiron, Lilith, and the four major asteroids in one table. This particular ephemeris is good for those who are not yet familiar with the planets’ symbols or glyphs–or simply prefer the written word–as it uses abbreviations for the planets, asteroids, and signs. specify an observing point with respect to a user-input artifical satellite. User-Defined TLE Objects as ObservatoriesThe lower left table shows sign changes and retrograde/direct activity. First, sign changes are displayed in the table under the ephemeris under the title “Ingresses.” Second, the “Stations” section shows planets and precise dates and times when they change direction, either retrograde (marked with an Rx) or direct (marked with a D). These appear only if there is a directional change.

Psyche in the natal chart represents the soul and the mind. It can represent love, passion, fear of betrayal, envy, fragility, vulnerability when we are in love, and other sensitive relationship dynamics. It is about getting to know our relationship needs and learning to trust. Karri Muinonen 1,2* Elizaveta Uvarova 1 Julia Martikainen 3 Antti Penttilä 1 Alberto Cellino 4 Xiaobin Wang 5,6 In the case of convex inversion, after in-depth studies using least squares and MCMC, the error model for relative photometry was chosen to be the conventional one presented in Muinonen et al. (2020), whereas the error model for absolute photometry was taken to be the one with a unit weight for each dense ground-based lightcurve. The latter, conservative error model was required to account for, primarily, the systematic errors arising from the forward modeling of the inverse problem. Likewise, in ellipsoid inversion concerning both relative and absolute photometry, a unit weight was assigned for each dense ground-based lightcurve. is requested, “n.a.” symbols will appear in output (meaning “not available”). 2. Osculating orbital elements table The following ephemerides are for the following selected asteroids: Eros, Psyche, Sappho, Ceres, Pallas, Juno, Vesta, and Chiron.If reading an ephemeris isn’t your cup of tea, but you want to know your Eros and Psyche signs, see our Eros and Psyche Sign Tables. terrestrial frames used with maps and GPS to specify surface locations. Universal Time (TDB -> UT Conversion) Provides access to key solar system data and flexible production of highly accurate ephemerides for solar system objects. A bit slow; helps in identifying asteroids that may be important for a particular chart, which you can then specify as Additional Objects. Probably best combined with the Sort by Degrees of Zodiac option. This is useful too.

Sappho in the natal chart represents same-sex relationships, friendship, love, romantic sensitivity, poetry, and romantic yearning. Finally, an asteroid’s spectrum from the ultraviolet (UV) through the visible (Vis) to the near-infrared (NIR) regime is known to vary with phase angle, evidently due to the fact that the phase function depends on the intrinsic brightness of the asteroid at a given wavelength. In the present work, we have confirmed that the shape and rotational parameters of the asteroid and the geometry of illumination and observation have an effect on the asteroid’s photometric phase function. The effect is different for different geometric albedos. Thus, the asteroid’s UV-Vis-NIR spectrum can depend on the shape and rotation parameters and vary as a function of the geometry of illumination and observation. It can be particularly enlightening to consider laboratory spectrometric measurements, such as those by Cloutis et al. (2012), extended to analogs of complete asteroids. The phase curve effects on the UV-Vis-NIR spectrometry and spectropolarimetry of asteroids remain as an open problem for future theoretical, observational, and experimental studies. Data Availability StatementPsyche in the natal chart represents the soul and the mind. It can represent love, passion, fear of betrayal, envy, fragility, vulnerability when we are in love, and other sensitive relationship dynamics. Yearly/monthly ephemerides offer daily zodiacal longitudes/positions of planets, asteroids, and points. The ephemerides above show the daily positions, month to month in the year 2021, of the four major asteroids, Chiron, and the minor asteroids Eros, Psyche, and Sappho.

We have extended the Bayesian lightcurve inversion methods to allow for full retrieval of phase functions with their uncertainties and applied the methods to a set of some 500 asteroids with both ground-based and Gaia photometry. In comparison to earlier work, certain differences are seen in the mapping from apparent phase curves to intrinsic phase functions. These differences may derive, to an extent, from the scarce amount of Gaia DR2 photometry, and we expect to resolve the issues with the forthcoming Gaia DR3 photometry.

Publisher’s Note Ephemerides in PDF for the planets with Chiron, Lilith, and True North Node: 2023 Ephemeris (PDF), 2024 Ephemeris (PDF), 2025 Ephemeris (PDF), 2026 Ephemeris (PDF), 2027 Ephemeris (PDF), 2028 Ephemeris (PDF) , 2029 Ephemeris (PDF) The “Stations” section shows planets when they change direction, either retrograde (marked with an Rx) or direct (marked with a D). Next, the middle table shows the lunar sign ingresses (or sign changes). These are separated because the Moon changes signs so much more frequently than the Sun and other planets/bodies. The void Moon times are also displayed.The ephemerides above display each planet, asteroid, or point by degree and sign (longitude) at Midnight in the Eastern time zone at a daily rate. With an ephemeris, we can follow their daily progress/movement and get a good understanding of sign change dates. The inverse methods are here applied to the ∼500 asteroids with ground-based and Gaia DR2 lightcurve data and to the simulated lightcurve data of the GS-asteroid. 4.1 Asteroids of Gaia Data Release 2 astro database Famous People born Today Famous People by Date of Birth Celebrity Astro Search Engine
