Optical and hard X-ray detections of an outburst from Aquila X-1
We report a new outburst from the neutron star X-ray transient Aquila X-1. Optical monitoring with the Faulkes Telescopes North and South show a rise above quiescence by 0.4 mag in V and i' on 2009-03-07. The magnitudes on that date (MJD 54897.76) were V=18.82 +- 0.09; i'=17.32 +- 0.12. Three days before, on 2009-03-04 (MJD 54894.65) we had V=19.31
