Description:
The First Byurakan Survey (FBS) is the largest and the first systematic
objective prism survey of the extragalactic sky. It covers 17,000 sq.deg.
in the Northern sky together with a high galactic latitudes region in the
Southern sky. The FBS has been carried out by B.E. Markarian, V.A.
Lipovetski and J.A. Stepanian in 1965-1980 with the Byurakan Observatory
102/132/213 cm (40"/52"/84") Schmidt telescope using 1.5 deg. prism. Each
FBS plate contains low-dispersion spectra of some 15,000-20,000 objects;
the whole survey consists of about 20,000,000 objects.

This is a form-based service allowing users to run simple
queries against GAVO Data Center's ivoa.obscore table, with
some nods to users looking of data near the optical waveband.
For serious use, the `obscore table`_ should be queried through
TAP.
Note that queries without spatial constraints may take time out. You
probably ought to switch to async TAP if you really want to run such
queries.

The LIFE Target Star Database contains information useful
for the planned `LIFE mission`_ (mid-ir, nulling
interferometer in space). It characterizes possible
target systems including information about stellar,
planetary and disk properties. The data itself is mainly
a collection from different other catalogs.
Note that LIFE's target database is living
data. The content – and to some extent even structure – of these
tables may change at any time without prior warning.

Solar Radio Emission Observations at “Orbita” Radio Polygon

Publisher:
Fesenkov Astrophysical Institute
Description:
The “Orbita” Radio Polygon at an altitude of 2750 meters conducts solar radio emission observations using state-of-the-art equipment. 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).
The data is collected and provided by the Institute of Ionosphere (https://ionos.kz/).
