α-Scorpiid meteor shower

Saturday, 2018, April 28 - 01:00

The α–Scorpiid meteor shower will reach its maximum rate of activity on 28 April 2018. 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 12 days old at the time of peak activity, and being so close to Full Moon, will severely limit the observations that will be possible.

The radiant of the α–Scorpiid meteor shower is at around right ascension 16h20m, declination -24°, as shown by the green cross on the planetarium above. At midnight, it appears 4° above your south-eastern horizon from London (click to change). All of the meteors will appear to be travelling directly outward from this point, as indicated by the white lines drawn above.

To see the most meteors, the best place to look is not directly at the radiant itself, but at any dark patch of sky which is around 30–40° away from it. It is at a distance of around this distance from the radiant that meteors will show reasonably long trails without being too spread out.
