Alma-Ata Station Neutron Monitor Data Service Service Info
The Alma-Ata Cosmic Ray Station operates the 18NM-64 neutron supermonitor at an altitude of 3340 meters above sea level with a geomagnetic cutoff rigidity of 6.7 GeV.

Photometric and Spectral Data of Galactic Wolf-Rayet Stars (WN sequence) Service Info
This catalogue contains results of photometric and spectral observations of 11 Galactic Wolf-Rayet stars of the WN sequence, obtained in 2021–2022 at the Fesenkov Astrophysical Institute (FAI), Kazakhstan. The programme included moderately bright stars (mostly fainter than V = 10m) observed in B, V, and Rc photometric filters, and medium-resolution spectra for measurement of absolute fluxes in prominent emission lines. For each object the table provides: identifiers (WR catalogue number, alternative name), spectral subtype, equatorial coordinates (J2000), literature photometry (B_cat, V_cat), reference codes, date of observation, measured B, V, Rc magnitudes and their errors, and absolute fluxes and equivalent widths for a set of emission lines, including He II λ4540, N III λ4619, He II λ4685, He II + H I λ4859, N V λ4945, He II λ5411, He II λ6560, He II λ6583, and N IV λ7109. Variability at the level of 0.1–0.15 mag in brightness was detected for WR 1, WR 120, WR 151, and WR 152. Changes in emission-line fluxes were found in WR 120, WR 128, and WR 145.

Planetary Nebulae: results of abs spectroscopy Service Info
This table contains compiled data on Galactic planetary nebulae based on absolute optical spectroscopy. It is primarily derived from spectroscopic observations, supplemented by selected values from other sources. Based on these data, physical characteristics of the nebulae were calculated, including sizes, densities, temperatures, and parameters of the central stars. For each object, the table includes its identifiers, excitation class, and interstellar extinction at H_beta. Morphological and distance-related properties are given through angular diameters (Diam_arcsec), physical sizes (Diam_pc), and distances (D_kpc). Electron densities are derived from [SII] 6717/6731 ratios. Effective temperatures of central stars were estimated using both Zanstra method (T_HI) and empirical calibrations based on [OIII] lines (T0_[OIII], T1_[OIII]), corresponding to the beginning and end of the observational interval. These values are expressed in 10**4 K units. The columns delta_t_obs_year and delta_t_model_year provide the duration of available observations and the time span over which the photoionization model reproduces observed changes. Model number and progenitor mass were taken from M. Bertolami (2016, A&A 588, A25; doi:10.1051/0004-6361/201526577). The age of the nebula is estimated from the same model set. Absolute fluxes of emission lines are provided for H_beta HeII 4685, [OIII] 5007, H_alpha, [NII] 6583, HeI 6678, [SII] 6717/6731, HeI 7065, [ArIII] 7136, and [OI] 7324. Each flux entry includes a measurement uncertainty; all fluxes are in erg cm**-2 s**-1. A separate column indicates the power-of-ten exponent to be applied where applicable. The final column lists reference codes for the sources of spectroscopic data, primarily indicating the source of absolute flux calibration for H_beta and associated lines. The table is provided in a machine-readable format. For each quantity, values are organized into separate columns: value, uncertainty, and, where applicable, a power-of-ten exponent (e.g., value * 10**power). This structure ensures precise numerical handling and interoperability with Virtual Observatory tools and pipelines.

This includes instruments for monitoring solar radio flux at frequencies of 1 GHz and 2.8 GHz, as well as the Callisto solar radio spectrograph, which is part of the international e-Callisto network. These tools enable the detection of solar radio bursts of types II, III, IV, and V, and provide valuable insights for forecasting the geo-effectiveness of solar flare activity. The provided dataset consists of daily tables, where each table corresponds to a single observation day. The data includes two columns: * timestamp: The time of observation at the detector. * SFU: The solar flux unit measurement, representing the intensity of solar radio emission in SFU (Solar Flux Units).
