  2. MEXART MEXART islocated in Michoacan, Mexico (19°48’ N 101°41’ W). Itis a radio telescope dedicated to carry out observations of distant radio sources at 140 MHz. The aim is to perform solar wind studies using the Interplanetary Scintillation (IPS) technique. ANTENNA. The antenna is a plane array of 64 rows of 64 dipoles (4096 dipoles) aligned in E-W direction, covering 9600 m2. Technical Characteristics Operation frequency: 139.65 MHz Basic element : dipole (λ= 2.15 m) Band width : 2 MHz Time constant: 47 ms Sampling rate: 20 ms Efective area (1/4 of array): 1650 m2. Effective area (full array): 6600 m2. FWHM in E-W direction of beams: 1°

  4. Currentconfiguration of MEXART • Thetechnicalteam moved thehalfantenna (G1 and G2) totheotherhalf (to G3 and G4). Thisprocessgavetheopportunitytocheckand fixtechnicaldetails. • Thetechnicalteambought new amplifierswich are goingtoincreasethesignal-to-noise ratio in a 30 %. • At thismoment, MEXART isoperatingwithonly a quater of the total array, butwe are expectingthat MEXART startsitsoperationwith a half of thearrayonAugust.
