Peculiar outburst of the newly revealed variable star V838 Mon

We present photometric and high- and low-resolution spectroscopic observations of the unusual outburst of V838 Mon. The data were collected at the NAO Rozhen, Bulgaria and at the Torun Observatory, Poland. Analysis of the peculiar behavior of the spectrum of the star is given. The star's radial velocity of +60 km/s is derived. A brief discussion concerning the nature of the object is also given.

The double outburst of the unique object V838 Mon

We present spectroscopic and photometric observations of the recent peculiar outburst of V838 Mon, carried out at Rozhen and Torun observatories. Our data cover a period of three months beginning just before the second eruption. The evolution of the outburst is divided into four phases. The changes of particular spectral features for each of these phases are shortly discussed.
