Sept 24 (Reuters) - The Baltic Exchange's main sea freight index, which tracks rates for ships carrying dry bulk commodities, rose slightly on Tuesday ending a 13-session losing streak, as higher demand for capesize vessels offset a fall in panamax demand.
* The Baltic index, which reflects rates for capesize, panamax and supramax vessels, rose 8 points, or 0.4%, to 2,116 points.
* The capesize index was up 79 points, or 2%, to 3,982 points, also posting its first rise in 14 sessions.
* The average daily earnings for capesizes, which typically transports 170,000-180,000 tonne cargoes such as iron ore and coal, increased by $467 to $30,278.
* The panamax index fell 39 points, or 2%, to 1,939 points.
* Average daily earnings for panamaxes, which usually carries coal or grain cargoes of about 60,000 tonnes to 70,000 tonnes, dropped $314 to $15,517.
* The supramax index fell by 4 points to 1,294 points. (Reporting by Harshith Aranya in Bengaluru; Editing by Shailesh Kuber)
