Description
Near infrared monitoring taken with the 1.5 m Carlos Sanchez Telescope in Tenerife of the decline of 3C279 during its 1988 outburst is presented. These data are combined with visible monitoring and data from the literature to examine the behavior of the light curve from B to K. A maximum in the infrared light curve was observed in June 1989 which was comparable at maximum to that seen in 1988. The 1988-89 outburst thus resembles closely that of 1936. Only weak evidence is seen of a correlation between (B - V) and m(V). Stronger correlations are observed between the measured infrared color indices and between the infrared brightness and color. The infrared continuum reddens as 3C279 fades, in agreement with behavior of the optical continuum of other Optically Violent Variables.

    An ultra-short-period super-Earth with an extremely high density and an outer companion
    We present the discovery and characterization of a new multi-planetary system around the Sun-like star K2-360 (EPIC 201595106). K2-360 was first identified in K2 photometry as the host of an ultra-short-period (USP) planet candidate with a period of 0.88 d. We obtained follow-up transit photometry, confirming the star as the host of the signal

    Neural calibration of imaging Stokes polarimeters
    Current polarimetric calibration techniques derive the instrument modulation matrix by numerically fitting an instrumental model to measurements of a set of calibration Stokes vectors. These techniques are typically limited to an error on the retrieved normalized Stokes Q, U and V parameters, in the $1\times10^{-2}$ to $1\times10^{-3}$ range. This

    Model-based identification of solar coronal mass ejections using deep neural networks
    Coronal mass ejections (CMEs) are a major driver of space weather and thus can have important negative technological and social impacts. To assess their geoeffectiveness once they are ejected, it is crucial their prompt identification in coronagraph images. In the last decade, deep neural networks (DNN) have experienced enormous improvements in
