We investigate the interplanetary conditions during 135 less stricthigh-intensity, long-duration, continuous AE activity (HILDCAA*) events betweenthe years 1998-2007. The HILDCAA* events were chosen by following the three"traditional" criteria which describe the high-intensity, long-duration,continuous AE activity (HILDCAA). However, we include a small modification inthe criteria that considers: "the AE values do not drop below 200 nT for morethan 2 h at a time". This criteria is modified by changing 2 to 4 hours periodin which the AE values should not drop below 200 nT. Once the events areselected, we perform a statistical analysis of the interplanetary parametersduring their occurrences. The distribution of HILDCAA* events along the solarcycle shows a pattern of double peak, with a peak around the maximum of thesunspot cycle, and an other in the descending phase. This kind of distributionis similar to the distribution of low-latitude coronal holes. For each of theHILDCAA* events, we have found its related Interplanetary Magnetic Field (IMF)and plasma parameter signatures. The average values of AE, AU, AL, and Dstindices, the density and temperature of the solar wind protons, the solar windspeed, the Bz component of the IMF, the IMF intensity, dynamic pressure, andplasma beta, among all the 135 HILDCAA* events, found here are: AE (348.1 $\pm$67.1 nT), AU (123.9 $\pm$ 34.2 nT), AL (-224.2 $\pm$ 47.3 nT), Dst (-22.1 $\pm$9.1 nT), Density (4.3 $\pm$ 1.3 cm-3), Temperature (170976.3 $\pm$ 58049.9 K),Flow speed (547.1 $\pm$ 83.9 km/s), Bz (-0.70 $\pm$ 0.88 nT), IMF magnitudeaverage (6.6 $\pm$ 1.2 nT), pressure (2.4 $\pm$ 0.6 nPa), and plasma Beta (0.66$\pm$ 0.27).
