46824 Tambora           Discovered 1998 June 26 by E. W. Elst at the European Southern Observatory.
Mount Tambora on the island of Sumbawa (Indonesia) is an active volcano that exploded in April 1815. It was the most powerful eruption in recorded history, and resulted in a brief period of significant world-wide climate change, including the "Year without a Summer" (1816).
