The η–Aquarid meteor shower will reach its maximum rate of activity on 6 May 2015. Some shooting stars associated with the shower are expected to be visible each night from 24 Apr to 20 May.

The maximum rate of meteors expected to be visible from a dark location is around 40 per hour (ZHR). The Moon will be 18 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 η–Aquarid meteor shower is at around right ascension 21h50m, declination -1°. At midnight, it appears 10° below your eastern 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.
