Mukul Ranjan Kundu (10 February 1930 – 16 June 2010), was an Indian solar physicist, known best as a pioneer of radio observations of the Sun.
Early in his career, he showed that the Sun's 10.7 centimetre radio flux is correlated with the level of ionisation in the Earth's ionosphere.
He served on the editorial board of the journal Solar Physics and was awarded the George Ellery Hale Prize in 2007.
[2] In 1965, he return to India to join the Tata Institute of Fundamental Research until 1968, when he became a full professor at the University of Maryland, College Park, where he remained until his death on 16 June 2010.
[2] Kundu's most influential work was a textbook, Solar Radio Astronomy, which was published by Wiley in 1965.
