We report the results of the temporal and spectral analysis of the longest BeppoSAX pointing (about 770 ks) of the microquasar GRS 1915+105, performed in October 2000. The source was mainly observed in the variability class ρ characterized by series of sharp pulses with a typical recurrence time of about 50 s. This behaviour was generally stable but, occasionally, it changed to a more irregular state. A spectral analysis of the 1–100 keV emission showed a small but significant change of the disk temperature between the regular and irregular ρ-mode. © 2005 American Institute of Physics [ABSTRACT FROM AUTHOR]
