Subject: [IMO-News] 1999 Leonid STORM data
Dear colleagues,
Again the Tempel-Tuttle meteors appeared by hundreds. From Spain our =
congratulations with Drs. David Asher and Robert Mc Naught for their =
successful prospect on Leonid's 1999 activity. Below you can find our =
first detailed results. All members of the Spanish Photographic Meteor =
Network (SPMN) has work the past night in an intensive campaign from =
five stations of Valencia and Castellon provinces. Also other four =
stations were established in Madrid and Sevilla.
The participating people in our SPMN project are: Joan Ma. Bullon, Juli =
Castellano, Angela del Castillo, Rodrigo Castillo, Alberto =
Castro-Tirado, Rafael Ferrando, Jos=E9 Gomez, Antonio Gutierrez, Carles =
Labordena, Fernando L=F3pez, Carles Pineda, Rafael Ramirez, Julian Ruiz, =
Natatxa Sanchez and Helena Valero.
Here you are our first results. From them considering a aprox. =
population index value of 2.5 we obtain a preliminary ZHR near to 3000 =
meteors by hour in the half-hour interval 01h45-02h15 UT. In the maximum =
the activity surpassed clearly a meteor by second and the continuous =
bandles difficult the counting. That's way probably our rates in the =
interval 02h10-02h20 UT are lower that the real meteor level. Please =
note that due to the high activity from 01h00 up to 03h30 UT we obtain =
only counts (no magnitude distributions), each observer in different =
time intervals.=20
In the next hours we send reports from other observers.
