Description
The effect produced by a sharp discontinuity in the upper boundary of the conductosphere is analysed in order to evaluate the distortions introduced in geomagnetic variation profiles in the long-period range of the spectra. To do so, a conformal mapping method is applied and the results are compared with the ones obtained in the case of lateral homogeneity. This model is also applied to interpret the internal part of the geomagnetic daily variations at the equatorial zones of Peru and central Africa.

    WEAVE First Light Observations: Origin and Dynamics of the Shock Front in Stephan's Quintet
    We present a detailed study of the large-scale shock front in Stephan's Quintet, a by-product of past and ongoing interactions. Using integral-field spectroscopy from the new William Herschel Telescope Enhanced Area Velocity Explorer (WEAVE), recent 144 MHz observations from the LOFAR Two-metre Sky Survey, and archival data from the Very Large

    A giant planet transiting a 3-Myr protostar with a misaligned disk
    Astronomers have found more than a dozen planets transiting stars that are 10–40 million years old 1, but younger transiting planets have remained elusive. The lack of such discoveries may be because planets have not fully formed at this age or because our view is blocked by the protoplanetary disk. However, we now know that many outer disks are

    Assessing your Observatory's Impact: Best Practices in Establishing and Maintaining Observatory Bibliographies
    Observatories need to measure and evaluate the scientific output and overall impact of their facilities. An observatory bibliography consists of the papers published using that observatory's data, typically gathered by searching the major journals for relevant keywords. Recently, the volume of literature and methods by which the publications pool
