                         and low-latitude ionosphere to M and X class solar ares events 
                         that were registered in the descending phase of the solar cycle 
                         24. It is well established that extreme solar ares may cause 
                         sudden changes in the ionospheric ionization density, including 
                         the equatorial and low latitudes regions. Therefore, we 
                         investigated the in uence of the solar ares in the ionospheric 
                         regions. It is based on a quantitative analysis of the time delay 
                         between the ionospheric response of the M and X class solar are 
                         events, as well as the intensity of such response. To perform 
                         this, we analyzed data from ionosondes installed in S~ao Lus - MA 
                         (2o 31' S, 44o 16' W), Cachoeira Paulista - SP (22o 39' S, 45o 00' 
                         W) and Boa Vista - RR (02o 49' N, 60o 40' W) during records of 
                         X-Ray ow changes associated with solar ares covering the period 
                         from 2014 to 2015 . Our results show the disappearance of echoes 
                         in the ionogram (knwon as HF radio blackouts) during the are event 
                         indicating absorption of radio signals in the D region, in which 
                         the response time depended of the solar are intensity.",
