Celestial Highlights for November

Posted: Sunday, November 3rd, 2013

by Robert Victor and Robert D. Miller

The full November 2013 Sky Calendar is available online at

A common, yet often striking event, is the monthly pairing of Venus and the crescent Moon. In the closing 10 weeks of Venus’ current evening apparition, pairings will occur at dusk on Nov. 6, Dec. 5, and on Jan. 1 and 2. The pairing at dusk on Thursday, Dec. 5 will be very impressive, because around that date, Venus will attain its greatest brilliance and highest position in the evening sky. That afternoon, the Moon can even help the observer spot Venus as they move together across the daytime sky. 

Jupiter is usually the planet next in brilliance after Venus, so its pairings near the Moon, occurring at intervals of 27-28 days, are also impressive. The Moon must always be in crescent phase when it is seen near Venus, but can appear in any phase when it passes Jupiter. (Why is that?!) This month Jupiter will appear near the Moon on the night of Nov. 21-22, from four hours after sunset until dawn.

Venus appears at greatest elongation, appearing a maximum of 47° from the Sun in our sky, on 2013 Oct. 31 in the afternoon and evening sky, and on the morning of March 22, 2014. Near those dates, when viewed with a telescope Venus appears as a tiny “half moon.” About midway between those dates, on Jan. 11, 2014, Venus passes nearly between Earth and Sun, and appears as a large, very thin crescent. Five weeks before and after this inferior conjunction with the Sun, Venus reaches greatest brilliancy and appears through binoculars as a crescent about 25 percent illuminated. The 20 weeks from the end of October to late March will be an exciting time to follow Venus through telescopes and binoculars as the backlit planet swings close to Earth and displays all its crescent phases, in the daytime as well as at dusk or dawn.

On our evening twilight chart for November 2013, bright objects are plotted for each day when the Sun has sunk to 9° below the horizon, at “mid-twilight”. By then it is easy to see Venus and about half a dozen stars of first magnitude or brighter, including the Summer Triangle of Vega, Altair, and Deneb high in the western sky. In November, mid-twilight in southern California (lat. 34° N) occurs about 40-43 minutes after sunset, and 45-48 minutes after sunset for the northern border of the state (lat. 42° N).

Planet positions are represented by a separate dot for each date, with positions for each Friday in November (1, 8, 15, 22, 29), represented by a larger dot and labeled. Rotate the chart until the portion of the horizon circle nearest to your target objects is below them, and you’ll see them depicted at the same orientation as they appear in the sky.

On the chart, stars’ daily positions are not plotted as individual dots, but instead by continuous tracks as the stars drift west (counter-clockwise around the North Star) in the course of the month, owing to the Earth’s revolution around the Sun.

Jupiter does not appear on November’s evening twilight chart. On Nov. 1 it rises within 4.5 hours after sunset. Its rising time shifts earlier by about 4 minutes per day, until at month’s end it will rise a few minutes before Venus sets.

Jupiter is also present in the morning, as the brightest “star” then visible. In mid-twilight, find it very high in SW on Nov. 1, moving to about halfway from horizon to overhead in west at month’s end. The other morning planet in view for entire month is Mars. In November find the red planet just over halfway up, drifting through SE early in month, ending in SSE.

Two additional planets join the morning scene as they emerge from the Sun’s glare. The November chart depicting the sky in morning mid-twilight illustrates the changing positions of the four morning planets. First, Mercury pulls out from its Nov. 1 inferior conjunction on the near side of Sun to be spotted by Nov. 8. Look low in ESE, to lower left of Spica. Mercury brightens, rapidly at first, then more slowly. Next, just after midmonth, Saturn emerges from far side of the Sun to appear to lower left of Mercury. The two planets form a close pair on Nov. 25-26 and switch places as speedy Mercury moves around toward the far side of its orbit. Saturn appears higher each morning because of the Earth’s faster orbital motion. The sample Sky Calendar at illustrates their arrangement on these and several adjacent mornings.

The calendar also shows the waning crescent Moon near Mars on Nov. 27, near Spica on Nov. 29, and near Saturn and Mercury on Dec. 1.

On Thanksgiving morning, Nov. 28, the four planets, Mercury-Saturn-Mars-Jupiter, span 120° across the sky. Later that same day, Comet ISON will pass within 725,000 miles of the Sun’s surface and make a sharp turn to the north, or upper left of the predawn Sun. Visit for updates on the comet. The November and December issues of Sky Calendar provide illustrations of its location for selected mornings.

Abrams Planetarium has created a new webpage especially for teachers at

We plan to add files to it, so you might want to check it regularly. At present, you will find downloadable files including:

  • The November 2013 Sky Calendar and evening sky map.
  • Monthly charts depicting the sky at evening and morning mid-twilight from October 2013 through December 2014, with descriptions of the evening charts. (Descriptions of the morning charts will be added later.)
  • A 2-foot by 2-foot poster showing the orbits of the six inner planets out to Saturn, with a data table for plotting the positions of the planets and a set of questions about star and planet visibility.
  • Information on the next apparition of Halley’s Comet, in 2061. (Start making plans now!)
  • Video previews of Comet ISON’s visit in November-December 2013 and of Comet Halley’s visit in July-August 2061.
  • Information about the four total lunar eclipses in 2014-2015. A version of this information applicable to California is available here.

Thriving in a Time of Change

Posted: Wednesday, September 13th, 2017

by Jill Grace

By the time this message is posted online, most schools across California will have been in session for at least a month (if not longer, and hat tip to that bunch!). Long enough to get a good sense of who the kids in your classroom are and to get into that groove and momentum of the daily flow of teaching. It’s also very likely that for many of you who weren’t a part of a large grant initiative or in a district that set wheels in motion sooner, this is the first year you will really try to shift instruction to align to the Next Generation Science Standards (NGSS). I’m not going to lie to you, it’s a challenging year – change is hard. Change is even harder when there’s not a playbook to go by.  But as someone who has had the very great privilege of walking alongside teachers going through that change for the past two years and being able to glimpse at what this looks like for different demographics across that state, there are three things I hope you will hold on to. These are things I have come to learn will overshadow the challenge: a growth mindset will get you far, one is a very powerful number, and it’s about the kids. Learn More…

If You Are Not Teaching Science Then You Are Not Teaching Common Core

“Science and Social Studies can be taught for the last half hour of the day on Fridays”

– Elementary school principal

Anyone concerned with the teaching of science in elementary school is keenly aware of the problem of time. Kids need to learn to read, and learning to read takes time, nobody disputes that. So Common Core ELA can seem like the enemy of science. This was a big concern to me as I started looking at the curriculum that my district had adopted for Common Core ELA. I’ve been through those years where teachers are learning a new curriculum, and know first-hand how a new curriculum can become the focus of attention- sucking all the air out of the room.

Tools for Creating NGSS Standards Based Lessons

Posted: Tuesday, August 29th, 2017

by Elizabeth Cooke

Think back on your own experiences with learning science in school. Were you required to memorize disjointed facts without understanding the concepts?

Science Education Background

In the past, science education focused on rote memorization and learning disjointed ideas. Elementary and secondary students in today’s science classes are fortunate now that science instruction has shifted from students demonstrating what they know to students demonstrating how they are able to apply their knowledge. Science education that reflects the Next Generation Science Standards challenges students to conduct investigations. As students explore phenomena and discrepant events they engage in academic discourse guided by focus questions from their teachers or student generated questions of that arise from analyzing data and creating and revising models that explain natural phenomena.
