23rd October 2014 Partial Solar Eclipse

RASC_handbookThe Royal Astronomical Society of Canada publishes each year its Observer’s Handbook, which is a wonderful reference of astronomical data and phenomena of the year. Its target time period is mainly relevant for the year of publication, but much of its content is a wealth of information applicable to any time period of the epoch.  The 2014 RASC Handbook noted four eclipses of the year, a total lunar eclipse in mid-April followed by an annular solar eclipse two weeks later (which was visible only in the far southern and eastern hemispheres), then another total lunar eclipse in early October and finally a partial solar eclipse on 23 October. This last solar eclipse was well situated for us observers in the western edge of North America.

The San Jose Astronomical Association hosted an event at its base camp, San Jose’s Houge Park for this partial solar eclipse. The objective is to allow people to safely view the eclipse, share views with each other and the public, and to simply socialize.  The club’s solar workhorse of a telescope, a 100mm hydrogen alpha scope made by Lunt, was doing its thing. A host of other telescopes were set up by club members and other people, many of which had filters attached for safe viewing, or projection systems installed so that the image could be viewed by many people at once, not unlike viewing the event on a small smartphone screen. Some people even brought out colanders, ie, spaghetti strainers, the holes of which act as numerous pin hole cameras, projecting numerous crescent sun images onto the ground, a white piece of paper, or even a hand.
long focal length imageSpecial solar viewing glasses, which make it safe for people to look directly at the sun, were made available to all attendees.  Kids and adults alike were able to wrap these glasses across their eyes and have a safe, direct view at anytime.  And when we did, we were treated not just to a portion of the moon covering the sun, but there was also an additional treat: An unusually enormous sunspot was clearly visible to the naked eye.  Everyone who knew what they were looking at could easily spot the aberration on the face of the sun.  What made this special is that sunspots are typically much smaller, and not visible without some amount of magnification.  The eclipse today was accentuated by this sunspot, which did not at any time become obscured by the moon’s limb, and whose size is fairly rare.
During the roughly three and a half hours of the event, an estimated seventy five people attended. Some were seasoned amateur astronomers who were ready with their own equipment, while others were families that stumbled across the event and were invited over by friendly volunteers of the SJAA.  Kids and retirees alike viewed the eclipse (and sunspot) in amazement, while everyone enjoyed the mild autumn weather of northern California.
This will be the last solar eclipse that will be visible in California for the next few years. In August of 2017, however, a large swath of North America, in particular the United States, will host a total eclipse come through.  This will be a highly anticipated event, so now is the time to plan for seeing this total eclipse, which should be on everyone’s list of thousand-things-to-do-before-you-die!

1st Sunday Oct 5th Solar

Observe The Sun Safely! Never look at the Sun without a proper filter!
Solar Programs are held 1st Sunday of every Month 2:00-4:00 PM at Houge Park weather permitting.
Click Here For Details

Another SJAA Member goes H-Alpha – 3 major prominences – notable filamentary “proms” – Sunspot Count 106 (NOAA) – unusually good seeing
Please welcome Paul Mancuso to the H-Alpha wave where one casually observes the 4th state of matter. Paul still uses his vintage Questar but he out fitted it with a front and back H-Alpha Filter system. Notable Companies that sell these filter sets are Lunt, Day Star and Coronado. Below is Paul M. with his scope and Michael P. showing off the Magnetic Sun Poster.

Wolf brought his recently acquired 100mm Lunt. Wolf dropped a washer and Terry pulled out her metal detector – no joking! Well OK there was lots of joking. The washer was found under Wolf’s car.

Terry and Bill are Solar Sunday’s regulars as is “Calcium K” Carl. Below is a pic Carl (foreground) Bill (background) and a pic of Terry at her scope with more of today’s visitors. About 20 folks both public and SJAA members stopped by to take a gander at the Sun.

Below is another pic of Bill’s scope. That’s not Bill either.

And of course Telescope Fit-it was going on inside. Here are a pics of Dave, Ed, and Phil.

That’s the news from Lake Wobegon. Stay Stellar, stay bright, stay warm and check out the stars at night.
