A new era for the Adaptive Optics. MAORY the Multi Conjugate Adaptive Optics RelaY for E-ELT entered in a new era. After the agreement signed on December 10 between INAF and ESO (which is building the telescope), on February 2 the MAORY kick-off meeting held


V404 Cygni outburst observed at Loiano

The R light curve of V404 Cyg, obtained by BFOSC on June 20th, 2015 (observations by Ivan Bruni and Silvia Sclavi). the light curve of a nearby star, derived in the same way, is plotted for comparison (the  right-hand Y axis refers to this star).

The X-ray binary V404 Cygni underwent an outburst detected in the X-ray band by Swift on June 18, 2015. One of the components of this source is a black hole weighing about 10 solar masses, and it is the first time since 1989 that it displays such activity. Using the imager/spectrometer BFOSC at the 1.52m

RR Lyrae stars in the Large Magellanic Cloud as seen by Gaia


Left panels: G-band light curves of RR Lyrae stars in the Large Magellanic Cloud observed by Gaia during the EPSL scanning. Right panels: I-band light curves obtained for the same stars by the OGLE IV survey. All light curves cover a 1.5 pulsation cycle.
