Contents:
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
