Plasma sheet parameters were synchronously measured onboard INTERBALL-1 (∼ 15 RE, 01h MLT) and GEOTAIL (∼ 22RE, 23h MLT) spacecraft during the isolated substorm development on November 16, 1995. The flux increase of high-energetic particles was detected by the both spacecraft at the substorm explosive phase. Simultaneously, a substitution of more rarefied and heated plasma for pre-existed cold and dense constituent was recorded onboard the INTERBALL spacecraft. However, such a substitution of heated plasma was recorded onboard the GEOTAIL only 1 hour later, after having recorded a series of fast burst flows. Based on observations of midlatitude magnetic variations, we derived the position and dynamics of the substorm current system. As a result, it was revealed that INTERBALL-1 was located inside the active region of the magnetosphere tail, while GEOTAIL was outside it; this fact explains the difference between plasma heating as observed onboard the two spacecraft. The localized plasma sheet heating and different response of the energetic and thermal particles at the substorm explosion phase are the novel results. These observations are discussed here in terms of the model of local burst magnetic reconnection.
