1. Introduction

Golenetskii et al. (GCN Circ. 16444) reported the GRB detection. The long-duration GRB 140621A has been observed by Konus-Wind, Fermi(GBM trigger 425073013), Swift (BAT), Suzaku (WAM), and INTEGRAL (SPI-ACS), so far, at about 71411 s UT (19:50:11). Table 1 contains the best reported positions from Swift.

Table 2 is a summary of GCN Circulars about this GRB from observatories other than Swift.
