We analyze here two very bright fireballs produced by the ablation in theatmosphere of two large meteoroids in 2009 and 2010. These slow-moving anddeep-penetrating events were observed over Spain in the framework of ourSpanish Fireball Network continuous meteor monitoring campaign. The analysis ofthe emission spectrum imaged for one of these fireballs has provided the firstclues about the chemical nature of the progenitor meteoroids. The orbitalparameters of these particles suggests a likely association with the recentlyidentified July rho-Herculid meteoroid stream. In addition, considerationsabout the likely parent body of this stream are also made on the basis oforbital dissimilarity criteria. This orbital analysis reveals that bothmeteoroids and PHA 2007LQ19 exhibit a similar evolution during a time period ofalmost 8,000 years, which suggests that either this NEO is the potential parentof these particles or that this NEO and both meteoroids had a common progenitorin the past.
