摘要：
Abstract: A study is performed of morning polar bay-like magnetic disturbances observed at latitudes above 70° MLAT with no simultaneous geomagnetic activity at lower latitudes. It is shown that such disturbances can be caused by the spatial expansion of both nighttime substorms and daytime polar magnetic bays to the morning side, along with the generation of convective magnetic bays. The simultaneous development of nighttime substorms and convective polar bays is typical. It is shown that individual events of morning polar magnetic bays observed during the development of nighttime substorms can be accompanied by mid-latitude positive morning magnetic bays. © 2022, Allerton Press, Inc.
