    Observations of Ellerman bomb emission features in He i D3 and He i 10 830 Å
    Context. Ellerman bombs (EBs) are short-lived emission features, characterised by extended wing emission in hydrogen Balmer lines. Until now, no distinct...

    Observations of Jupiter around 80 microns at high spectral resolution
    High-resolution (up to 0.02 kayser) airborne spectral observations of Jupiter in the range from 105 to 140 kaysers are presented. The procedures used to remove...

    Observations of Sagittarius A* during the pericenter passage of the G2 object with MAGIC
    Context. We present the results of a multi-year monitoring campaign of the Galactic center (GC) with the MAGIC telescopes. These observations were primarily...

    Observations of the J = 2 - 1 transitions of /C-12/ /O-16/ and /C-12/ /O-18/ towards galactic H II regions
    Observations are reported of the J = 2 → 1 transitions of CO and 12C18O at 230 and 219 GHz respectively from a number of galactic sources. A map of the central...

    Observations of the magnetars 4U 0142+61 and 1E 2259+586 with the MAGIC telescopes
    Context. Magnetars are an extreme, highly magnetized class of isolated neutron stars whose large X-ray luminosity is believed to be driven by their high...

    Observations of the recurrent M 31 transient XMMU J004215.8+411924 with Swift, Chandra, HST, and Einstein
    Context. The transient X-ray source XMMU J004215.8+411924 within M 31 was found to be in outburst again in the 2010 May 27 Chandra observation. We present...

    Observations of umbral flashes in the resonant sunspot chromosphere
    Context. In sunspot umbrae, the core of some chromospheric lines exhibits periodic brightness enhancements known as umbral flashes. The consensus is that they...

    Observations, compositional, and physical characterization of near-Earth and Mars-crosser asteroids from a spectroscopic survey
    Aims: We analyse a significantly large sample of spectroscopic data to provide a compositional characterization of the near-Earth asteroid population. We...

    Observed and computed UV spectral distribution of A and F stars
    An automatic and fast procedure was implemented to determine Te and log g from the comparison of the UV S 2/68 spectra with the Kurucz models. The method has...
