  We have analyzed publicly available RXTE/PCAs archival data of GRS 1915+105
during its burst/flaring state. The burst cycle ranges from 30 to 1300 s. These
bursts are different from the type I and type II classical bursts seen in Low
Mass X-ray Binaries (LMXBs) in terms of their temporal and spectral properties.
We have classified these bursts on the basis of properties observed during the
quiescent (low flux) phase. The 2 - 10 Hz QPOs are present during the quiescent
phase and disappear during the burst phase of all types of these X-ray bursts.
The duration of the quiescent phase can be explained assuming an outflow from
the post-shock regions and the catastrophic Compton cooling.
