May 10-13 geomagnetic storm was the strongest geomagnetic storm occurred in decades. It has generated a significant attention among scientists as well as public and media, since auroral emissions were observed at extremely low latitudes throughout the globe. Here, we report an interesting event of Bursty Bulk Flows (BBFs), short--lived fast flows in the central magnetotail, and their impacts on the magnetosphere-ionosphere coupling during this event using the Multi-scale Atmosphere Geospace Environment (MAGE) model at NASA Community Coordinated Modeling Center (CCMC). BBFs occur often in the magnetotail, however, this phenomena is new as we observed multiple BBFs generated along a circular arc of same L-shell during the recovery phase of Gannon storm. Emission of interchange waves were also present at the same time period of these BBFs. We believe there is a connection between these two phenomena. Simulation results are compared to observational evidences of BBFs, wave activities, and auroral signatures during this event.
