  We present multi-wavelength observations by Chandrayaan-2/XSM, SDO/AIA and
Hinode/XRT of a B-class flare observed on 25th February, 2021, originating from
an active region (AR 12804) near the North-West limb. The microflare lasts for
approx 30 mins and is composed of hot loops reaching temperatures of 10 MK. We
report excellent agreement (within 20 percent) for the average effective
temperatures obtained at the flare peak from all the three instruments, which
have different temperature sensitivities. The XRT filter combination of Be-thin
and Be-med provides an excellent opportunity to measure the high-temperatures
in such microflare events. The elemental abundances during the evolution of the
microflare are also studied and observed to drop towards photospheric values at
the flare peak time, compared to coronal values during the rise and decay
phase. This is consistent with previous XSM studies.
