We observed the Fermi short GRB200826A (Fermi GBM Team GCN 28284; Mangan
et al. GCN 28287) with the Giant Metrewave Radio Telescope (uGMRT),
India, beginning 2020 September 9.53 UT (14.47 days after the burst) at
a central frequency of 1.25 GHz. We report non-detection of radio
afterglow from GRB200826A, with no evidence of radio emission above a
3-sigma upper limit of 48.6 microJy/beam. The final image has a
resolution of 4.13 arcsec by 1.65 arcsec at a position angle of 83.10
degrees. We thank the staff of the GMRT that made these observations
possible.
