(meteorobs) New Lirid data

	Dear colleagues,

	Mr. Arlt has announced in the IMO Circular an enhanced activity of Lirids. Also our team of the Spanish Photographic Meteor Network (PSMN) of SOMYCE has noted an important activity of Lirids in 1999. We organised several networks the past days to study the shower around the maximum (April 20-23th) but unfortunately the sky was cloudy. Only reliable data has been obtained in multiple stations developed the 18th and 25th April. These nights were also rich in Lirids. 

	At this moment, I have available only my reduced data. We will send in the next days more data, including one observation of 21th April. Please note as an advance my meteor visual observations:
