The Swift/BAT transient monitor confirms the current outburst from the Be/X-ray binary pulsar, H 1417-624 ( = 2S 1417-624) (Nakajima et al., ATel #11479). In the BAT 15-50 keV energy band, the outburst began approximately on 20 March 2018 (MJD 57467) and the count rate has been steadily rising since that time. On 23 April 2016 (MJD 58232), the count rate was 0.079 +/- 0.011 ct s-1 cm-2 (15-50 keV), or about 350 mCrab. This is already brighter in Swift/BAT than the giant X-ray outburst of November 2009 (Krimm et al., ATel #2276), when it peaked at around 300 mCrab.
