We present an observational study of the interacting pair of dwarf galaxies,MCG+07-20-052, in the vicinity of Milky Way mass spiral galaxy NGC 2998.MCG+07-20-052 is located at a sky-projected distance of 105 kpc from NGC 2998and the two have a relative line-of-sight velocity of 60 kms. We observed tidaltail-like extensions on both members (D1 and D2) of the interacting pairMCG+07-20-052. The interacting dwarf galaxies, D1 and D2, have B-band absolutemagnitudes of $-$17.17 and $-$17.14 mag, respectively, and D2 is significantlybluer than D1. We obtained HI 21 cm line data of the NGC 2998 system using theGiant Metrewave Radio Telescope (GMRT) to get a more detailed view of theneutral hydrogen (HI) emission in the interacting dwarf galaxies and in thegalaxy members of the NGC 2998 group. Evidence of a merger between the dwarfgalaxies in the MCG+07-20-052 is also present in the HI kinematics andmorphology where we find that the HI is mostly concentrated around D2, whichalso shows a higher level of star-forming activity and bluer $g-r$ color indexcompared to D1. In addition, we detect extended tenuous HI emission aroundanother member galaxy, NGC 3006, located close to the MCG+07-20-052-pair at asky-projected distance of 41 kpc. We compare here our results from theMCG+07-20-052 pair-NGC 2998 system with other known LMC-SMC-Milky Way typesystems and discuss the possible origin of the dwarf-dwarf interaction.
