An eclipse of a star by a minor planet over India as a catalyst for future astronomical research |
We describe the upcoming eclipse of the asteroid 22 Kalliope over portions of India. It is the author's second trip to India after an initial success near Delhi on October 3, 2015. The Kalliope eclipse event provides an opportunity to capture data using inexpensive off-the-shelf technology that is expected to lead to an improvement of the 3-dimensional model of this large asteroid. Amateur astronomers can easily use the technique of "pre-pointing" without the need for telescope motor drives to allow the Earth to act as a substitute tracking device. The new spacecraft GAIA has finished initial imaging of over 1 billion stars and this has resulted in major advances in the prediction of such eclipses. We also characterize future eclipses of 4 other stars by other minor planets that will cross the Indian sub continent in 2017. |
