The Lyrids have been observed in the Netherlands and Belgium with very fine weather!
Nightsky proved to be completely clear from observing locations across the two countries!
Almost a record number of observers observed the Lyrids and were not disappointed while
rates were satisfactory (about equal as expected) and some fine meteors appeared.
One such fine Lyride meteor has been photographed by Jean-Marie Biets from Wilderen, Belgium about 30 km south-west of Hasselt.
The Lyrid meteor appeared on April 22 at 01h52m41s UT.
