NAZOV / TITLE :

Talk on interstellar comet, one PHA and two binaries

ABSTRAKT / ABSTRACT :

I will talk about some selected interesting results obtained during past
year with both telescopes at the Skalnate Pleso Observatory.

    1. Comet Borisov was the second object with the interstellar origin.
    Only ~4 months it could be observed from northern hemisphere and we
    performed few BVR photometric measurements using 0.61-m and 1.3-m 
    telescopes at the Skalnate Pleso Observatory. Estimates of color, 
    size, mass loss, etc. will be shown.

    2. In late October the Earth was visited by PHA 1998 HL1. This event
    was a perfect challenge to make good multicolor & polarimetric
    observations and to estimate some physical characteristics (period, 
    taxon.class, size).

    3. Short talk on two binary asteroids. One is ideal for binary system
    modeling and other is interesting due to "unpredictable" eclips/occultation
    moments.
