Solar flares are among the most energetic events in our solar system. They occur around sunspots as magnetic field lines hold potential energies that are suddenly released due to magnetic reconnection. The Sun is currently in a very active phase, meaning that sunspots are more common. In this talk, I will present an observation of a solar flare that was co-observed with multiple instruments. Utilizing multiple instruments enables us to study the event at different temperatures which is important to increase our knowledge of the physical properties that drive a flare event. The flare is well observed with the Swedish 1-m Solar Telescope (SST) which mainly covers the complex chromosphere in which there are still open questions on how this part is heated. Finally, I will present some preliminary results.
