About this deal

about -53 mas from the IAU2006/00A of-date system. International Terrestrial Reference Frame (ITRF93) Other reference frames developed relative to the ICRF in Horizons include: Earth true equator and equinox of date (TOD) 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.

Provides access to key solar system data and flexible production of highly accurate ephemerides for solar system objects.

Sappho in the natal chart represents same-sex relationships, friendship, love, romantic sensitivity, poetry, and romantic yearning. You can compare your Eros sign with your partner’s Psyche sign, and then do the reverse — compare your Psyche sign with your partner’s Eros sign — to get a good idea how you two combine on a romantic and sexual level.

Eros in Astrology: Signs for 1940-2010 1940 Note that the four major asteroids, included in the monthly ephemerides above for the year 2025, are Ceres, Juno, Vesta, and Pallas. Also added are Eros, Sappho, Psyche, and Chiron. This was a custom ephemeris built using the excellent and highly recommended software program, Sirius 3.0. 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

The reviewer AC declared a past collaboration with the author AC to the handling editor. Publisher’s Note Note: Time is Noon GMT. If you’re in a different time zone other than UT or GMT, you will need to adjust for the time zone offset. For example, UT is 5 hours ahead of Eastern Time and 8 hours ahead of Pacific Time. Yearly/monthly ephemerides offer daily zodiacal longitudes/positions of planets, asteroids, and points.

Full Moons & New Moons 2023 Eclipses Solar & Lunar 2023 Void of Course Moon 2023 Gardening Moon Calendar Fertility Days (Lunar Conception) In the lower right table of the ephemeris under the title, “Lunar Phases & Eclipses,” lists the lunar phases (New, First Quarter, Full, and Last Quarter) dates, times, and zodiacal positions. If there is a Solar or Lunar eclipse in that particular month, you’ll find its date and positions in this table, below the lunar phases. Otherwise, you can assume there isn’t an eclipse that month (eclipses occur in sets approximately every 5-6 months). Photometric phase curves provide information about the intrinsic light-scattering properties of the surface that are intimately related to the regolith composition and structure. Since the composition and structure determine also the reflectance properties observed at different wavelengths, phase curves are strictly related to the taxonomic classification of asteroids. Phase curves are often represented with the help of a few parameters. The classical two-parameter H, G magnitude system has been used for a long time ( Bowell et al., 1989). H is the asteroid’s absolute magnitude, namely the magnitude (corresponding to unit distance from the Sun and the observer) measured at zero phase angle, and G is a parameter describing the overall variation of magnitude at different phase angles, including a nonlinear brightness surge at phase angles smaller than 10° (opposition effect). In recent years, it has been replaced by the so-called H, G 1, G 2 magnitude system, a three-parameter model developed by Muinonen et al. (2010) to remove the caveats of the H, G system in the case of low-albedo and high-albedo asteroids. Further refinements and applications of the H, G 1, G 2 system have been published, among others, by Penttilä et al. (2016) and Shevchenko et al. (2016).

The MCMC inverse methods are based on proposal probability densities characterized with the help of the so-called virtual least-squares solutions and are described in detail by Muinonen et al. (2020). In what follows, we introduce the error models for the observations and the algorithm for the retrieval of absolute magnitudes and phase functions from DR2 photometry. 3.1 Error Models for Observations The following ephemerides are for selected asteroids: Eros, Psyche, Sappho, Ceres, Pallas, Juno, Vesta, and Chiron:We define sparse lightcurves as having photometric points timed, on average, more than the estimated rotation period apart. For sparse relative lightcurves, as for dense relative lightcurves, the points are calibrated against each other but not against absolute standards. In accordance with Muinonen et al. (2020), we set N k , e ff = N k ̃ in an error model coinciding with the form in Eq. 22, the index k ̃ now denoting the sparse lightcurve with the smallest number of observations. Finally, for sparse absolute lightcurves, we introduce a model that coincides with the one for the sparse relative lightcurves. Now the observations are, however, calibrated against absolute standards. Note that Eros is not always sexual, per se, as Eros also represents creative passion. In the chart, it can point to areas into which we pour a lot of heart, passion, and enthusiasm. b) you compute the position for one moment with the speed flag set. Then you look at the speed in longitude value, whether it is positive or negative. This value is found in xx[3].
