About this image

The April Lyrids are debris from comet C/1861 G1 (Thatcher) - not discovered by the politician - and the Earth passes through this stream in the second half of April. Their geocentric velocity (Vg) is 47 km/s, so they are fairly fast, midway between the trundling Taurids (~ 27 km/s) and the zippy Leonids (70 km/s). Their activity rates are often low, usually reaching a peak ZHR of around 10 to 15 which was expected this year in the early hours of April 22.

This bright Lyrid was captured a day before their maximum. It built up to apparent mag -1 then produced a terminal flare of almost mag -3. It left a glowing train. I've yet to check my captures from the night of maximum.
