The solar corona has many unsolved questions and one of the most important is how it is heated. However, the corona also hosts a cooling problem alongside the heating problem. The corona consists of large amounts of cool and dense material called coronal rain. This cool and dense plasma falling from coronal heights.

In this study, we report the SJI/IRIS observations of coronal rain at the East limb of the Sun observed on 2017 July, 2 between 07:28 UT and 12:55 UT in the 1400 Å and 2796 Å passband. We present here a spatial and temporal analysis of coronal rain. To detect coronal rain, we used the Rolling Hough Transforma (RHT) algorithm (Schad 2017). We calculated the amount of rain in both SJI channels. According to the pioneer results, much more rain was observed in SJI 2796 Å observations compared to the SJI 1400 Å.

On the other hand, we analyzed the up-flows and down-flows motion of coronal rain. Downflow motions are more dominant and this is consistent with the literature. We found 59.8 km/s and 49.3 km/s for the projected velocities in SJI 1400 Å and SJI 2796 Å, respectively. We also observed that the number of coronal rain events varies strongly with height and velocity.
