LEONA Initial Collaboration team Brazil: National Institute for Space Research – INPE (PI institution) Instituto Tecnológico SIMEPAR Peru: Jicamarca Radio Observatory – JRO, Peru Argentina: National University of Cordoba – NUC Astronomy and space Physics Institute - CONICET Russia: Lebedev Physical Institute – LPI, Russian Academy of Science ??? (You are invited to join!) TLE and High Energy Emissions related to Thunderstorms (HEET) spatial distribution and climatology in Latin America: not measured by satellites Ionospheric effects of lightning and TLEs in the ionosphere: e.g. Jicamarca and Julia Observatories Possible relationship with other phenomena: e.g. connection with gravity waves, high energy particle precipitation in SAMA HEET and TLE measurements in coordination with Auger measurements ??? Discovery of other optical phenomena ??? ??? (Other interesting topics are very welcome!) Research Interests:

Necessidades: - Local afastado das luzes da cidade - Boa visibilidade no horizonte - Céu claro no local - Segurança - Eletricidade - Internet Câmera CMOS intensificada de alta velocidade (até 67 mil fps) Remotely controlled video EMCCD cameras (30 fps) Manualy oerated high-speed instensfied video cameras (60,000 fps and more) for campaigns. TLE OBSERVATION EQUIPMENT Pan-titl controller (black) and pan-tilt with camera enclosures, for remote operation.

R EQUIREMENTS FOR TLE O BSERVATION RequirementsAuger Observation site away from city lights (TLEs have low luminosity)OK! Nighttime observations only to do not damage equipmentOK! Turn off all outdoors lights at the site during observations (sensitive cameras and lights can obfuscate the TLEs) Possible??? Clear sky on site (visible stars at low elevation) and thunderstorm ~ km away OK! Safety at the siteOK! Internet connection: - The cameras are operated remotely - Compressed images need to be sent at near real time to the observer to follow the TLE activity, and point the camera - The TLE data locally stored needs to be sent to the storage server at INPE after observations are done Possible??? Appropriated place to install camera with good visibility in the horizon/ low elevation angle: -Ideal: 360 o unobstructed view -Minimum: 180 o unobstructed view centered on West direction Possible??? (Visited Cohihueco site in July 2012, it has minimum requirement) Technical support: - A person to go check out the equipment in case there is any problemPossible???

LEONA TLE O BSERVATION AT AUGER Requirements for AugerAuger A small place in the terrace of Cohihueco site or other to put to camera Possible??? A small area inside to place the controller/storage PC + nobreak Possible??? Turn off all outdoors lights at the site during observations (sensitive cameras and lights can obfuscate the TLEs) Possible??? Power: 1000 W Possible??? Safety at the site Possible??? Internet connection: - Ideal band 512 kb/s - Realistic band 256 kb/s - Minimum band 120 kb/s Possible??? Minimum technical support from Auger personnelPossible???
