The α–Scorpiid meteor shower will reach its maximum rate of activity on 13 May 2015. Some shooting stars associated with the shower are expected to be visible each night from 20 Apr to 19 May.

The maximum rate of meteors expected to be visible from a dark location is around 5 per hour (ZHR). The Moon will be 25 days old at the time of peak activity, and so will present minimal interference.

The radiant of the α–Scorpiid meteor shower is at around right ascension 16h20m, declination -24°. At midnight, it appears 13° above your southern horizon from London (click to change). All of the meteors will appear to be travelling directly outward from this point.

The best place to look to see as many meteors as possible is not at the radiant itself, but at any dark patch of sky which is around 90° away from it, since it is at a distance of around 90° from the radiant that meteors will typically appear at their brightest.
