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).
As observed previously in Pushchino, the H2O maser G25.65+1.05 had a
strong flare in November-December 2016, its peak flux density
exceeding 40000 Jy (paper submitted to Astronomy Reports).
Follow-up observations of this source are highly desirable.
