| 23.07-24.07 | - Gamma-ray burst follow up observations
Multi wavelength optical observations play significant role in a complex investigation of gamma-ray burst’ counterparts such as prompt emission, afterglow, supernova and kilonova. Optical observations of GRB host galaxies allow determining their red shift and morphological type. Multi wavelength light curves allow to provide computer simulation and to get physical parameters of the burst and its supernova/kilonova component.

| 18.08-23.08 | - Spectral Study of Carbon Stars in the Halo
Numerous of periodic variables were found during the analysis of variable star candidates within a 20.000 deg. sq. region covered by the Catalina Survey Data Release-1(CSDR1) and many optically faint periodic variable stars obtained by the asteroid survey LINEAR across 10.000 deg. sq. area of the northern sky survey at high galactic latitudes. The majority of these variables have not been cataloged yet. Objects presented in both Catalogues are useful for a wide variety of research topics such as studies of Galactic Halo structure and the physics of pulsating stars.

| 12.09-16.09 | - Search of outflows in young stellar clusters
The first task is the search of the collimated outflows in young stellar objects (YSOs) in the optical range (HH-objects). For our observation, we select the several ten star-forming regions, about which we have the information about the presence or absence sings of outflows in the NIR, MIR and radio wavelengths, but no data in the optical range. We plan to obtain the deep images of these star-forming regions through Ha and [SII] filters and compared the common data about outflow activity in different wavelength with properties of environment interstellar matter, as well with evolution stages and masses of YSOs.
The second task is the photometric monitoring in R and I bands of several PMS stars. According to the observation data obtained during 2000-2010, the mentioned above PMS objects stars show the brightness variability from 0.5 to 2 magnitudes. We plan to continue photometric monitoring of these objects in order to reveal the periodicity of the brightness variability.

| 13.10-04.11 | - Speckle interferometry of binary stars
This program is being carried out in accordance with the agreement between the BAO (Armenia), OARMA (Spain) and SAO (Russia). The OARMA speckle EMCCD camera will be attached to the 2.6m telescope at BAO in order to perform measurements of binaries, relative positions and differential photometry. We think that a period of at least 20 nights is the minimal necessary time in order to perform a large collection of measurements. It is important to take into account that 2 days will be used to attached the camera to the telescope and check all the operations.
