  We present a detailed analysis of an eruptive event that occurred on early
2019 March 8 in active region AR 12734, to which we refer as the International
Women's day event. The event under study is intriguing in several aspects: 1)
low-coronal eruptive signatures come in ''pairs'' (a double-peak flare, two
coronal dimmings, and two EUV waves); 2) although the event is characterized by
a complete chain of eruptive signatures, the corresponding coronagraphic
signatures are weak; 3) although the source region of the eruption is located
close to the center of the solar disc and the eruption is thus presumably
Earth-directed, heliospheric signatures are very weak with little Earth-impact.
We analyze a number of multi-spacecraft and multi-instrument (both
remote-sensing and in situ) observations, including Soft X-ray, (extreme-)
ultraviolet (E)UV), radio and white-light emission, as well as plasma, magnetic
field and particle measurements. We employ 3D NLFF modeling to investigate the
coronal magnetic field configuration in and around the active region, the GCS
model to make a 3D reconstruction of the CME geometry and the 3D MHD numerical
model EUHFORIA to model the background state of the heliosphere. Our results
indicate two subsequent eruptions of two systems of sheared and twisted
magnetic fields, which merge already in the upper corona and start to evolve
further out as a single entity. The large-scale magnetic field significantly
influences both, the early and the interplanetary evolution of the structure.
During the first eruption the stability of the overlying field was disrupted
which enabled the second eruption. We find that during the propagation in the
interplanetary space the large-scale magnetic field, i.e. , the location of
heliospheric current sheet between the AR and the Earth likely influences
propagation and the evolution of the erupted structure(s).
