Review By Christof Wiedemair

“I had the great pleasure to work with Vikrant from Cepheid observatory India on the measurement of the parallax of the comet 46P/Wirtanen some time ago. He is a very kind person and he agreed to help us with our task right away. The data he contributed were very precise and so the result turned out accurately, too. Since then, I follow the activities of the Cepheid observatory group on their website and am always very impressed by their high versatility and their diligence. Keep it up, Vikrant & friends!”
