Trading timings of the Bombay Stock Exchange and the National Stock Exchange will be revised from Tuesday till March 18, as the sun's position may disrupt connectivity, causing difficulties in receiving data via satellites.

The "sun outage" as it is known, will take place from March 4 to 18 between 11.45 am and 12.25 pm, during which traders and investors may face some loss of connectivity.

Accordingly, the two exchanges will stop trading between 11.45 am and 12.25 pm and resume trading from 12.30 pm, a stock exchange circular said.

Trading on the bourses will start at 9.55 am and close at 4.15 pm local time owing to the sun outage, the exchanges said.
