AB: We report on a few recent and interesting observations of coronal mass ejections associated with eruptive filaments recorded in multiwavelengths using various data sets obtained from ground- and space-based observatories. These include chromospheric observations in H-alpha and the inner coronal data recorded from Mauna Loa Solar observatory (MLSO). The CME recorded in white light observations from the LASCO/SoHO is included in the analysis. In this paper, we attempt to investigate the pre-eruptive scenario of these events leading up to the eventual eruption. The role of the restructuring of the magnetic field and changes in the magnetic field due to the emergence and cancellation of magnetic flux in the source region of the CME will be discussed.
