samarasinhaThe speaker will be Dr. Nalin Samarasinha, a Senior Scientist at the Planetary Science Institute in Tucson.

Dr. Samarasinha received his PhD from University of Maryland where his studies focused on cometary science. A portion of his PhD work involved studying the rotational state of comet 1P/Halley — first “tumbling” comet or asteroid. Over the last three decades, he has investigated the dynamical and physical processes occurring in the comae and nuclei of many comets and he has over 50 peer-reviewed publications. Asteroid 12871 is named for him in recognition of his contributions to cometary science.

His talk will be about the global campaign to monitor comae of three comets which will come close to Earth in 2017 and 2018 where amateur astronomers can make significant contributions.

Astronomy Day at Kartchner Caverns State Park – October 1, 2016

The next Kartchner Caverns State Park astronomy program will be Saturday, October 1, 2016.  The guest speaker will be Mr. Ken Zoll, the Executive Director of the Verde Valley Archeological Center.  His talk will be given in the Discovery Center auditorium at 5:30 pm.   Mr. Zoll will cover the results of his research in Archeo-Astronomy in Arizona.  He has studied archeological sites across the region, and during his program, he will show links between pictographs and astronomical events.

Starting in the early afternoon, the Huachuca Astronomy Club of Southeastern Arizona (HAC) will have solar telescopes set up for observing the sun.  If the skies are clear, we will see close-ups of sunspots and prominences through specially filtered astronomical telescopes.  After sunset about 7 pm and weather permitting, everyone will have another chance to look through the HAC telescopes.    Don’t miss the close-up views of the ringed planet Saturn, the red planet Mars, the Hercules star cluster (M13), and many other wonders of the night sky.   Sunset will be at about 6:05 pm, and bring your jackets.

This event is open to the public. There is a $7.00 per-car entry fee (up to 4 adults). There is no additional fee for parking. The telescopes will be setup in the bus parking area.
