Descripción
We report a new observation of Nova Vul 2007 (S. Nakano, IAUC 8861) obtained by the Swift X-ray Telescope (XRT) on 2008 June 18. The nova was detected at count rate of 0.023 count/s, representing a decline by a factor of 3 compared with Swift XRT observations obtained during 2007 November- December, and by about 50% compared with the previous observation obtained on 2007 December 27. The XRT spectrum is significantly softer than during the earlier epoch, with a ratio of X-ray counts in the 1-10 keV band to those in the 0.3-1 keV band having declined from about 1.0 to 0.4.

    The Gravitational-wave Optical Transient Observer (GOTO)
    The Gravitational-wave Optical Transient Observer (GOTO) is a project dedicated to identifying optical counterparts to gravitational-wave detections using a network of dedicated, wide-field telescopes. After almost a decade of design, construction, and commissioning work, the GOTO network is now fully operational with two antipodal sites: La Palma

    Innovative solution for upgrading commercial bearings for use in cryogenic instruments
    Infrared instruments for astronomy require many bearings for motion that must move in cryogenic conditions. There are poor and expensive options for this, and the companies with qualified bearings only supply after a long time. To attend these constrains, the Instituto de Astrofísica de Canarias (IAC) started to develop a procedure to upgrade

    NIRPS first light and early science: breaking the 1 m/s RV precision barrier at infrared wavelengths
    The Near-InfraRed Planet Searcher or NIRPS is a precision radial velocity spectrograph developed through collaborative efforts among laboratories in Switzerland, Canada, Brazil, France, Portugal and Spain. NIRPS extends to the 0.98-1.8 μm domain of the pioneering HARPS instrument at the La Silla 3.6-m telescope in Chile and it has achieved
