Powerful bursts of water masers towards G25.65+1.05

ABSTRACT The results of long-term monitoring of the Galactic 22.2 GHz water masers associated with G25.65+1.05 using several telescopes are presented. We report a powerful double flare with peak flux densities of ∼60 and 130 kJy in 2017 September and 2017 November, respectively. We propose a linear...

Description
Summary:ABSTRACT The results of long-term monitoring of the Galactic 22.2 GHz water masers associated with G25.65+1.05 using several telescopes are presented. We report a powerful double flare with peak flux densities of ∼60 and 130 kJy in 2017 September and 2017 November, respectively. We propose a linear relationship between the inverse of the square of the line width and the natural logarithm of the flux density of the flaring water maser feature. We infer from this that the flaring feature is unsaturated.
