I don't think I had ever heard of Khandro Pema Dechen before she was mentioned at the bottom of email I got from a listserve of Tulku Thondup's teachings.
Here's her picture and brief info:http://www.rigpawiki.org/index.php?titl ... ema_Dechen
"The photo below is a picture of Thigles (spheres made of colorful lights), which filled the sky during the cremation of Khandro Pema Dechen on September 9, 2006 in Sikkim, India. This is seen as a sign of her high Dzogchen attainment. Photograph by Tsewang Trungkar."
