Celestial Highlights for May 2015

Posted: Tuesday, May 5th, 2015

by Robert Victor with twilight sky maps by Robert D. Miller

Winter’s bright stars are departing in the west. In early May, while Mercury is visible, four planets can be seen simultaneously at dusk. Evenings from now well into July, three showpiece planets are available for telescopic observation. Venus and Jupiter are closing toward their spectacular rendezvous at the end of June.

In May, four of the 15 stars of first magnitude or brighter visible from mid-northern latitudes begin their annual leaves of absence, Evening Mid_Twilight. In order of departure, they are Rigel, Aldebaran, Sirius, and Betelgeuse. In June, Procyon, Capella, and Pollux will follow. These seven stars include all the stars of the huge Winter Hexagon, with Betelgeuse inside. It’s enjoyable and relaxing to look for these stars within an hour after sunset on clear spring evenings and use the DailySkywatchLog  to keep a record of which stars are seen. Those who watch regularly are certain to notice the stars appearing lower each evening at the same stage of twilight and eventually dropping out of view.

This change is a direct consequence of Earth’s annual revolution around the Sun. Follow link at the end of this article to the activity “Modeling seasonal visibility of stars and visibility of the planets.”

As seen from Earth from late April through mid-July, the Sun appears to move from Aries through Taurus into Gemini, causing these zodiac constellations and their neighbors to sink into the evening twilight glow, and, after several weeks, to reappear in the eastern sky at dawn. (Exception: Far northern Capella emerges at dawn before it leaves the evening sky.)

The Moon and naked-eye planets provide additional spice for skywatchers. In early May 2015, observers can view as many as four planets simultaneously with unobstructed views toward WNW and ESE. During May’s first week, Mercury shines near mag. 0, and on May 6, reaches its greatest angular distance from the Sun this time around, 21°. Around that date, Mercury also attains its highest position for this year at dusk. The best time to find it may be about one hour after sunset; look about 22° lower right of brilliant Venus. Also on May 6, find bright Jupiter 45° to Venus’ upper left. On May 6, wait until 1.4-1.5 hours after sunset, when Mercury is just 3° up in WNW. Then turn around to find Saturn about the same height above the opposite horizon, in ESE. The lineup of four planets Mercury-Venus-Jupiter-Saturn will span 173° across the sky.

Look a couple of minutes earlier each evening until May 11, and then you’ll find Mercury and Saturn 5° above opposite horizons 1.2 hours after sunset. But by then Mercury has faded to mag. +1.0, and it will fade rapidly in following days.

Much easier than catching four planets simultaneously in May 2015 is viewing three, and you can do so in all of May and well into July! The span of Venus-Jupiter-Saturn starts out 159° long on May 1, shrinking through 150° on May 9, 135° on May 22, to 125° on May 31.Venus and Saturn, the endpoints of the lineup, are both 10° up 2.5 hours after sunset on May 1, improving to 23° up at a very convenient viewing time of 1.3 hours after sunset by end of May. [Data for southern California.]

As a wonderful bonus, these three planets are the most impressive for telescopic observation: Venus starting in gibbous phase, two-thirds full at the start of May, passing through half full in early June, through ever larger and thinner crescent phases as the planet draws closer to Earth; Jupiter, with its cloud belts, and its four bright satellites discovered by Galileo (as were the phases of Venus); and Saturn with its amazing rings, now 24° from edge-on!

Excellent views of these showpiece planets available evenings in May into July 2015 make this a superb time to schedule evening sky watching sessions – star parties! – at schools, parks, camps, and elsewhere folks gather outdoors.

If you haven’t been following the 5-months-long approach of Venus to Jupiter in the evening sky, start now! Venus-Jupiter are 50° apart on May 1, closing to 35° apart on May 16, and 20° on June 1. The gap between the two brightest planets continues to narrow, to 10° on June 14, to 5° on June 21, and only 1/3 of a degree apart on June 30. This spectacular pairing of Venus-Jupiter will provide a great chance to do public astronomy outreach for several evenings around their closest approach on June 30. Illustrations appear on the Abrams Planetarium Sky Calendar, June and July issues.

Some Moon and planetary events in evening sky in May and early June

Many of these events are illustrated on the Abrams Planetarium Sky Calendar. A downloadable pdf of the May issue with an evening sky map may be reprinted and distributed free of charge. Go to www.abramsplanetarium.org/skycalendar/

On May 1 and 2 in evening twilight, watch the waxing gibbous Moon leapfrog past Spica. Full Moon occurs on the evening of May 3. On May 4-6 two hours after sunset, watch the waning gibbous Moon go past Saturn and Antares.

The Moon returns to early evening sky on May 19, as a thin crescent low in WNW, 21°-22° lower right of Venus. Two days later on May 21, Moon passes 9° lower left of Venus, which now forms an isosceles triangle with Gemini’s “Twin” stars Pollux and Castor. Jupiter is now 30° to Venus’ upper left. On May 23 the fat crescent Moon appears 6° lower left of Jupiter. Catch the half-full First Quarter Moon near Regulus on May 24, and a gibbous Moon near Spica on May 29.

On June 1, the nearly Full Moon appears in SE near Saturn and Antares, while Venus aligns with Pollux and Castor in WNW. That same evening, Jupiter appears 20° to Venus’s upper left, with just 29 days to go until their spectacular conjunction on June 30th!

On June 6 at dusk, Venus reaches greatest elongation, 45° from Sun. Now half full through telescopes, the planet is rounding the apparent end of its orbit as seen from Earth and is rapidly approaching us!

California Science Test Academy for Educators

Posted: Thursday, February 15th, 2018

California Science Test Academy for Educators

To support implementation of the California Science Test (CAST), the California Department of Education is partnering with Educational Testing Service and WestEd to offer a one-day CAST Academy for local educational agency (LEA) science educators, to be presented at three locations in California from 8:30 a.m. to 3:30 p.m. As an alternative to traveling, LEA teams can participate virtually via WebEx on one of the dates listed below.

The dates and locations for the CAST Academy are as follows:

  • Monday, April 23, 2018—Sacramento
  • Wednesday, April 25, 2018—Fresno
  • Thursday, April 26, 2018—Irvine

The CAST Academy will help participants develop a deeper understanding of the assessment design and expectations of the CAST. The academy also will provide information and activities designed to assist educators in their implementation of the California Next Generation Science Standards and three-dimensional learning to help them gain an understanding of how these new science assessment item types can inform teaching and learning. The CAST Academy dates above are intended for school and district science instructional leaders, including teacher leaders, teacher trainers, and instructional coaches. Additional trainings will be offered at a later date specifically for county staff. In addition, curriculum, professional development, and assessment leaders would benefit from this training.

A $100 registration fee will be charged for each person attending the in-person training. Each virtual team participating via WebEx will be charged $100 for up to 10 participants through one access point. Each workshop will have the capacity to accommodate a maximum of 50 virtual teams. Each virtual team will need to designate a lead, who is responsible for organizing the group locally. Registration and payment must be completed online at http://www.cvent.com/d/6tqg8k.

For more information regarding the CAST Academy, please contact Elizabeth Dilke, Program Coordinator, Educational Testing Service, by phone at 916-403-2407 or by e‑mail at caasppworkshops@ets.org.
