No Foolin' - ISS pass tonight 8:08 p.m. & Mojave and podcast news

by Jane Houston Jones

Hi astrofans Step outside tonight at 8:08 for a nice pass of the ISS 49° above the horizon at its highest! Get your own alerts here https://spotthestation.nasa.gov/ Thu Mar 31 8:08 PM, Visible: 6 min, Max Height: 49°, Appears: 10° above WSW, Disappears: 11° above NE My April Podcast appears today so it doesn't get mixed up in any April Fool spoofs. https://youtu.be/af0zVX8nIBc And our semi-annual Mojave National Preserve star party is May 7th. It is free, and the Black Canyon Group Campground is reserved for us for the 15th time courtesy of the Mojave National Preserve Conservancy and the National Preserve and the National Preserve. http://mojavepreserve.org/index.php/site/article/star_party_in_the_mojave_n… We'll turn our gaze (and our telescopes) away from the Milky Way and peer out at galaxies in May. We won't ignore the planets, either - it will be just a few weeks from Mars Opposition, and Mars has not appeared as large as it will be in May since 2005! Jupiter will also be putting on a great view, and we always keep a list of visible comets to show under the dark Mojave skies. It's osur favorite event, made even better by sharing with our friends like you. There are always a few people looking to share rides to the desert. I have one woman who would like to share the expense (and the driving) with another woman. Let me know if you are interested and I'll put you in contact with her. Any others - you can always post your intent on our OTAstro Facebook account. https://www.facebook.com/Old-Town-Sidewalk-Astronomers-1619991271586682/ or send me a private note. That's all for this month, literally! Jane -- Jane Houston Jones @jhjones What's Up April: Mercury, Mars, Jupiter, Lyrids! https://youtu.be/af0zVX8nIBc

Sidewalk Astronomy in Monrovia

by Morris Jones

Tonight the public forecast calls for "partly cloudy," and the Clear Sky Chart suggests not entirely transparent skies, but steady seeing. I'm going to anticipate a good viewing evening from the corner of Myrtle & Lime and try setting up a telescope. Sunset is at 7:03, and we'll try to be there from 7:00 - 9:00 p.m. We'll have a lovely gibbous moon, and Jupiter near opposition. With a good seeing forecast, I'm going to plan to bring out the giant 7-inch refractor -- a special treat. It should be pleasant weather, a little chilly, light winds. Best regards, Mojo -- Morris Jones Monrovia, CA http://whiteoaks.com

No sky tonight ...

by Morris Jones

No sidewalk astronomy in Monrovia tonight. It's not raining, but it's very unsettled in advance of the next storm. Monrovia is pretty well clouded out right now. We may try again next weekend, and may try for a special event on a Monday evening soon. We'll let you know! Best regards, Mojo -- Morris Jones Monrovia, CA http://whiteoaks.com

Jupiter season!

by Jane Houston Jones

March 8 is Jupiter Opposition - when Jupiter is on the opposite side of Earth from the sun, rising at sunset, setting at dawn and closest to Earth in its orbit. It will be a little brighter and a little closer to Earth before, during and after March 8. So don't worry if it is cloudy, you have several more months of excellent Jupiter viewing opportunities. The planet, with all its cloud patterns above and below the equator show well, even in the smallest telescope, and even with steady binoculars. The four Galilean moons Io, Europa, Callisto and Ganymede are also easy to see through steadily held binoculars, but much more easily seen in telescopes of all sizes -- except when they are passing behind the planet -- or in front. Near opposition, as a moon passes in front of Jupiter the sun, the moon's shadow appears against the clouds of Jupiter. Astrophotographers are capturing images showing the pearly spheres of Io and Europa and their shadows marching across the face of Jupiter all month long. There are 11 of these double shadow transits in March, and three of them are visible from the US. Unfortunately, they are all on Monday nights and end between 9:30 p.m. and 1:25 a.m. I doubt we'll get telescopes out after work, but we'll let you know if someone is available. In the meantime, make friends with that neighbor with a telescope! Dates and times March 15 02:22 UTC March 14 7:22 p.m. - 9:34 p.m. PDT (Pacific Daylight Time) March 22 04:23 UTC March 21 9:23 p.m. - 11:23 p.m. PDT March 29 07:00 UTC March 28, 12:00 a.m. - 1:25 a.m. PDT of the three, March 14/15 had the added bonus of volcanic Io overtaking Europa at the end of the transit. We animated both the shadow transits and a depiction of the view from above Jupiter and from Earth in my March What's Up Video https://youtu.be/MmTINt3vCSw If you have trouble with YouTube, here's the JPL version http://www.jpl.nasa.gov/video/details.php?id=1417 We're hoping to do sidewalk astronomy in Monrovia, weather and schedules permitting on either March 12 or 19th, maybe both.

Sidewalk Astronomy tonight!

by Jane Houston Jones

We've been weathered out and also many of us have been unavailable more than usual lately. But tonight should be a great night for Sidewalk Astronomy. Several of our gang will be out in Monrovia at the Library Park corner of Myrtle and Lime Streets tonight from about 6:30 until about 9. I say about, because Mojo and I won't be there, and I haven't hear the start time from the group. Have a good tone, look up, and I'll see you next month, hopefully. I'm almost recovered from hip replacement surgery, but haven't handled the telescopes yet. Jane Oh, the morning planet lineup is still gorgeous. Look southeast to southwest - the lineup spans the sky just before dawn. Here's my video all about it! https://youtu.be/EOo_qBNWpbc -- Jane Houston Jones @jhjones What's Up February 2016 video: Morning moon/planet meetups, a comet near Polaris, icy Uranus and icy Vesta meet near Valentine's Day. https://youtu.be/EOo_qBNWpbc

NIce high ISS pass over LA area tonight, plus What's Up December!

by Jane Houston Jones

HI everyone, tonight, Saturday the 5th of December step out to see a nice high ISS pass (LA residents primarily). Here are the details: Time: Sat Dec 05 5:40 PM, Visible: 3 min, Max Height: 61°, Appears: 34° above WSW, Disappears: 19° above NE . You can get your own alerts by signing up here. http://spotthestation.nasa.gov/ Mojo and I took a walk last night (first longish walk on my 2-week new hip) and marvelled at Orion rising sideways in the eastern sky. Have a look! Also, I talk about preparing for Mars Opposition in 2016 in my December What's Up video. Although you need to get up and look low to the eastern horizon around 3am to See Mars rise this month, it's visible until dawn - very pretty right now between brighter Venus and Jupiter. https://www.youtube.com/watch?v=hv8hVvJlcJQ I talk a bit about the Geminids and Ursids here on our sidewalk astro page (scroll to upcoming events) http://www.otastro.org/ Finally, Dec 19 would be our next sidewalk astronomy night, but I'm not sure who will be in town with telescopes. We'll update closer to the date. Keep looking up! Jane -- Jane Houston Jones Monrovia, CA @jhjones What's Up December: Mars now, even better in 2016 https://youtu.be/hv8hVvJlcJQ

Sidewalk Astronomy in Monrovia tonight!

by Jane Houston Jones

A few of our sidewalk astronomers will be out at Myrtle and Lime Street Saturday night for a few hours, say 5:30 p.m. to 7:30 p.m. I'll sit this one out since I'm a few days post hip-replacement surgery -- healing well, but not up to telescope viewing yet. If you can't get out or are clouded out, have a look at the moon phases in this month's What's Up Video: http://solarsystem.nasa.gov/…/…/11/03/whats-up-november-2015 <http://l.facebook.com/l.php?u=http%3A%2F%2Fsolarsystem.nasa.gov%2Fnews%2F20…> I've also started a new feature - the Star Tool Box. It's a work in progress right now, but contains supplementary info about the topic of each monthly video. So for November, not only can you print out a star chart(a few, actually) showing you the Apollo landing site locations on the moon, you can also find the Apollo Mission patches, landing site geology, and more. Here's the link: http://solarsystem.nasa.gov/news/startoolbox Hope you join us under the moonlight or at the armchair for some lunar sights.

Cancelling Sidewalk Astronomy tonight

by Jane Houston Jones

It's a little too hazy to drag us off the sofa and out to a mediocre sidewalk astronomy night. And none of the other astronomers are available tonight, it seems. In the meantime: Try really hard to wake up early tomorrow morning! There is a great planet lineup worthy of a wake-up call this week. The lineup of the three planets just above the rising sun in the east has been visible all month long, culminating in a tight cluster of the planets Venus, Mars and Jupiter from now until month end. Sunday morning, the brightest of the two Venus and Jupiter are very close together -- from our earthly vantage point. Don't miss Mars below the two bright ones. Fainter, but worthy of a look! Just use you eyes, binos if you have them. So step outside, look East and enjoy the show! Here's the lineup go.nasa.gov/1VHmy2E <https://t.co/uSm8UUS5YC> -- Jane Houston Jones @jhjones @NASAInsight What's Up podcast #99 Sept Eclipse! https://youtu.be/jXMZmEOGLRc
