The current re-brightening of the symbiotic star V919 Sgr
is just one of similar occurencies within the same outburst
the object entered in spring of 2007 (Munari et al. 2007,
CBET 999), so it is not a new outburst.
Multiple maxima, sometimes spaced by a year or more, is the
rule for outbursts of symbiotic stars, which usually need
many years to return to quiescence conditions after an
outburst phase sets in.
