Detection of a Bright H2O Maser Burst from G25.65+1.05 at the Simeiz Radio Telescope RT-22
Abstract
The source of maser emission in 22.235-GHz H2O line in the star-forming region G25.65+1.05 has experienced a new rapid flare. The peak flux density of the main feature at VLSR = 42.5 km/s was: 2017 April 26 - 600 Jy (Simeiz RT-22 radio telescope); 2017 May 12 - 400 Jy (Simeiz); 2017 June 13 - 410 Jy (Simeiz); 2017 July 25 - 316 Jy (Pushchino RT-22 radio telescope); 2017 August 10 - 620 Jy (Simeiz); 2017 August 21 - 840 Jy (HartRAO); 2017 August 25 - 813 Jy (Pushchino); 2017 August 27 - from 1400 Jy to 2500 Jy (Simeiz); 2017 September 7 - 17000 Jy (Simeiz); 2017 September 8 - 20500 Jy (Simeiz); 2017 September 9 - 21000 Jy (HartRAO).
