A new EA system, UniSi_V118 (UCAC4 458-084501 in Aquila) has been discovered from telescope of University of Siena by Fabio Salvaggio, Riccardo Papini, Alessandro Marchini and Massimo Banfi. Magnitude variation from 16.14 to 16.76. No secondary minima has been detected. Epoch: HJD 2458280.4701Period: 2.60546 d This is the link to VSX record: https://www.aavso.org/vsx/index.php?view=detail.top&oid=844783
A new EA system, UniSi_V117 (UCAC4 762-005092 in Cassiopeia) has been discovered from telescope of University of Siena with the help of members of the SSV-UAI: Fabio Salvaggio, Alessandro Marchini, Riccardo papini, Massimo banfi, Lorenzo barbieri, Claudio Arena, Nello Ruocco and Giorgio Bianciardi. It was difficult to calculate the correct period. ASAS-SN needed to be […]
This is the transit of WASP-3b in Lyra taken at WBRO on last 2019-09-04 with Giuseppe Marino, Riccardo Papini, Fabio Salvaggio and Massimo Banfi. Exposition is 180s, all frames are calibrated. These are the lightcurve and the system reconstruction based on data: Here is the link to ETD record: http://var2.astro.cz/tresca/transit-detail.php?id=1568056074&lang=en
