Context : IGR J19294+1816 was discovered by INTEGRAL in 2009 during a bright X-ray outburst and was classified as a possible Be X-ray binary or supergiant fast X-ray transient .

Aims : On 2010 October 28 , the source displayed a second X-ray outburst and a two months-long monitoring with Swift was carried out to follow the evolution of the source X-ray flux during the event .

Methods : We report on the INTEGRAL and Swift observations of the second X-ray outburst observed from IGR J19294+1816 .

Results : We detected pulsations in the X-ray emission from the source at \sim 12.5 s up to 50 keV .
The source X-ray flux decreased smoothly during the two months of observation , displaying only marginal spectral changes .
Owing to the relatively rapid decay of the source X-ray flux , no significant variations of the source spin period across the event could be measured .
This prevented a firm confirmation of the previously suggested orbital period of the source at 117 d. This periodicity was also searched for in archival Swift /BAT data .
We detected a marginally significant peak in the periodogram and determined the best period at 116.2 \pm 0.6 days ( estimated chance probability of a spurious detection 1 % ) .

Conclusions : The smooth decline of the source X-ray flux across the two months of observations after the onset of the second outburst , together with its relatively low value of the spin period and the absence of remarkable changes in the spectral parameters ( i.e. , the absorption column density ) , suggests that IGR J19294+1816 is most likely another member of the Be X-ray binaries discovered by INTEGRAL and not a supergiant fast X-ray transient .
