The 2017 May 20 $^{th}$ stellar occultation by the elongated centaur (95626) 2002 GZ $_{32}$

P. Santos-Sanz, J. L. Ortiz, B. Sicardy +56

We predicted a stellar occultation of the bright star Gaia DR1 4332852996360346368 (UCAC4 385-75921) (m $_{V}$ = 14.0 mag) by the centaur 2002 GZ $_{32}$ for 2017 May 20$^{\rm th}…

Optical observations of a SN 2002cx-like peculiar supernova SN 2013en in UGC 11369

Zheng-Wei Liu, Jujia Zhang, Fabrizio Ciabattari +7

We present optical observations of a SN 2002cx-like supernova SN 2013en in UGC 11369, spanning from a phase near maximum light (t= +1 d) to t= +60 d with respect to the R-band maxi…
