Abstract

We have made an estimation of the synchrotron peak frequency (ν_peak^s) for six very low synchrotron peaked (VLSP) blazars. These objects were selected as VLSP candidates (with the ν_peak^s ≤ 10¹³ Hz) from the archival data. We have build spectral energy distribution using quasi-simultaneous observations at the Zeiss-1000 and RATAN-600 telescopes of the Special astrophysical observatory of RAS and made an estimation of the ν_peak^s. We confirmed classification as a VLSP for two sources ([HB89] 1308+326 and 3C 345), for four other blazars we have calculated ν_peak^s>10¹³ Hz.
