In this study we make use of the Swarm counter-rotation constellation for estimating the typical scale length of the post-sunset equatorial plasma bubbles (EPBs) along fluxtubes. The close approaches between Swarm spacecraft near the equator occurred in September and October 2021. covering the magnetic local time from 19:00 to 23:00. which is favorable for the occurrence of EPBs. https://www.mamapaisa.com/product-category/stainless-steel-flat-iron/
