2017 Central New York Science and Engineering Fair (CNYSEF) – Request For Volunteers, 26 March 2017

Volunteers, judges and mentors are needed for the Central New York Science and Engineering Fair (CNYSEF) sponsored by the Museum of Science and Technology (MOST) on Sunday, March 26, 2017 at the SRC Arena on the Onondaga Community College campus. This year, students from ten counties will compete in two divisions, the junior fair for 4th-8th graders and the senior fair for 9th-12th graders. Judges don’t need to be experts in science to listen as the students demonstrate how much they have learned and accomplished. A continental breakfast, lunch and training will be provided for the judges and volunteers. Those interested in volunteering can apply online here. Reply to Earl Turner eturner@most.org if you have any questions.

The encouragement and interest shown by volunteers and judges is an essential part of the student’s science fair experience. Help inspire our future generation of scientists and engineers!

Observing Announcement: Spectacular Grazing Occultation Of Aldebaran On 4 March 2017

Greetings, fellow astrophiles!

The following came in from Brad Timerson of ASRAS and the International Occultation Timing Association (IOTA). We had a few posts back in 2014 about an occultation of the star Regulus by asteroid Erigone (on what turned out to be an overcast March 20th. For information about the event and the observing process, see the original CNYO occultation post.

Local observing path for the lunar occultation of Aldebaran on March 4th.

Folks in Rochester and between Syracuse and Binghamton are ideally placed to not only observe the occultation, but also to take data to provide to the IOTA. Information about the occultation, including links to how you can help with the observations, is provided in Brad’s original email below:

I want to alert the membership about this great opportunity (if the weather cooperates!) of seeing a lunar grazing occultation involving a bright star, Aldebaran, along the northern edge of the nearly first quarter moon on the evening of March 4, 2017. In small telescopes, it should be a spectacular sight.

IOTA (International Occultation and Timing Assoc.) has prepared a webpage outlining this event. If you scroll down the page, you will find a section for the Rochester area with a couple of static maps as well as a Google Map for the area. Graze events are dependent on distance from the predicted graze limit as well elevation above sea level. So, the Google Map has been created for the elevation in the Rochester area. (100 feet either way makes little difference)

Main webpage for event: occultations.org/aldebaran/2017march/

Direct link to Google map for approximate elevation in Rochester area: occultations.org/wp/wp-content/uploads/2016/12/500ft.htm

Zoom in to see path through your area. Set the line A to a value of +0.2 km (enter value in box and then press “Click here”). Set line B to –0.1 km. This will produce 2 gray lines, one just north and one just south of the green line. These 2 lines (with the green line in the middle) will mark the best locations for an observing site.

Based on recent grazes, it appears that you will want to be exactly on the green line shown on the Google map or just barely south of it to see the maximum number of events. Many of the events will be gradual or partial (the star not completely disappearing) because Aldebaran is a large star and at the moon’s distance, won’t be completely covered for some locations.

I plan on observing the graze from a store parking lot (after getting permission) along Rt. 96 near Clifton Springs, NY. Anyone near this area is welcome to join me. I will have more details on my location as the date approaches. I will be videotaping the event using a special camera and video time inserter so that important details of the lunar limb and, possibly, the star, can be determined.

Profile maps of the Aldebaran occultation from the IOTA page.

Central graze time for the Rochester area is 11:17:57 pm on the 4th. You’ll want to be setup well ahead of this time with a clear western horizon. The moon will be about 18° above the horizon. You may see events occur for up to a minute before and after this central graze time. Below is a profile of the lunar limb showing the predicted graze limit as well as a dotted line at about 0.2 km south of the limit. The gray bar graph at the left shows the number of events that can be expected to occur. Time is along the bottom with 11:17:57 pm centered.

Please email me individually (btimerson [_at symbol_] rochester.rr.com) if you’d like information about a specific site along the graze path. Include the latitude, longitude, and elevation of your site taken from Google Earth of the Google map. Also, any other questions you might have can be directed my way.

Here are links to the pages summarizing observations made at the last two grazes. Many observations have YouTube videos available so you can see what to expect.
