Luis reports that, whilst checking the sky outside the dome, he saw 9 meteors in 2-3 minutes, at around 03.00UT. From the Canary Islands the radiant is still quite low at this time of the morning, so the implied rate of activity is very high. This report is confirmed by Luis Lopez, Carlos Vazquez and Pablo Rodriquez of the Agrupacion Astronomica de Tenerife. Observing from a nearby site they registered 77 meteors in 80 minutes with 16 meteors in 6 minutes from 02.55-03.01UT. They estimate that the naked eye limit was about 6.5."
