Abstract : The solitary millisecond pulsar J2124-3358 with a period of rotation of 4.9 ms and a Dispersion Measure of 4.6 pc/cc at a distance of 410 pc from us, has several components in its flux profile. Observing it with the upgraded GMRT over a period of about a year, we see that the profile shows some signature of mode changes between its various components. K-S test and Monte-Carlo simulations support our initial results. J2124-3358 is already a well-timed pulsar at the uGMRT. Hence, discovering mode changes in this pulsar and accounting for them is likely to improve the precision of its times-of-arrival significantly.
