AX per eclipse

BF Cyg burst

CH Cygni campaign for A. Skopal

V694 Mon and its absorptions

Monitoring of Herbigrbig Ae/Be Z CMa

Note that we have two new projects:                                                                             Monitoring of the newly discovered symbiotic SU Lyn from Katarzyna Drozd (Nicolaus Copernicus Astronomical Centre) Campaign AG Dra Study of the next outburst, expected last spring, upon the request of Rudolf Gális, Jaroslav Merc & Laurits Leedjärv. A weekly monitoring at R > 1800 until the outburst and a daily coverage during the outburst.  Low res. spectra are welcome (good correction for instrumental/atmospheric response is required)and, if possible, flux calibrated.  A very interesting campaign for spring and summer.

Terry Bolhsen obtained a spectrum of Nova Cen 2013 more than 3 years after the outburst

Ongoing observations of V694 Mon, AX Per in eclipse …

BF Cygni : new burst detected by Augustin Skopal. Observations are recommended

CH Cygni : rising -  idem

Steve Shore suggests observing a sample of B[e] stars

Daniel Verilhac obtained a spectrum of  IRAS 07080+0605 with a LISA on MARS observatory telescope (600 mm) – (France, Ardèche)

Following the detection of an outburst of the Herbig Ae/Be star Z CMa, Fran Campos got  a spectrum with a DADOS 200 l/mm and Joan Guarro with its homebuilt Echelle

And Steve Shore’s notes : Molecules in your spectra
