Wed, 19 Apr 2017 - The Lyrids are approaching their 2017 peak

The Lyrid meteor shower is already active and is due to reach its annual peak on the morning of April 22nd (Saturday). Good news is that moonlight will not be an issue this year.

Despite producing somewhat lower peak rates than August's Perseids or December's Geminids, the Lyrids do stand out well against the rather low background meteor rates of the spring months.

The Lyrid radiant (see chart below) is above the horizon all night, being fairly low in the north east at first, but quite rapidly gaining altitude as the night progresses. The number of Lyrids seen will follow a similar pattern, steadily increasing as the radiant gets higher in the sky. The best observed rates are likely to be seen in the pre-dawn hour of Saturday morning.

The actual number of Lyrids seen will also depend on the darkness of your observing site. From a dark observing site, rates approaching a dozen Lyrids per hour may be reached on Saturday morning. Observed rates will be lower from less dark locations.

In addition to finding as dark an observing site as possible, make sure that you have a clear view of the sky. As always, to see the most Lyrids, don't look directly at the radiant area, but at an area of sky around 30 degrees from the radiant and around 50 degrees above the horizon. As ever, make sure that you are well wrapped up against the cold!
