Abstract (English):
The results of long-term monitoring of the Galactic maser source IRAS 18316-0602 (G25.65+1.05) in the water-vapor line at frequency f = 22.235 GHz (616- 523 transitioin) carried out on the 22-m Simeiz radio telescopes are reported. The accurate distance estimate for IRAS 18316-0602 (12.5 kpc) and the flux density at the flare maximum ( ≈ 1.3 × 105 Jy) makes this the most powerful Galactic kilomaser known.
