Rod Stubbings reports the recurrent nova V745 Scorpii is in outburst at magnitude 9.0V. Only two previous eruptions are known, one in 1937 and another in 1989.

A comprehensive history of this and all other known recurrent novae can be found in Comprehensive Photometric Histories of All Known Galactic Recurrent Novae by Schaefer, Bradley E., 2010ApJS..187..275S
 
Time series observations of this rare event are highly encouraged.
 
Congratulations to Rod on this rare detection!

The paper by Dr. Bradley Schaefer that Mike references in his post (2010ApJS..187..275S) is excellent. It is long (99 pages) but contains a lot of interesting material and makes extensive use of AAVSO observations of the 10 known galactic recurrent novae.

Good observing,  Elizabeth Waagen, AAVSO HQ
