Mojave Preserve Star Party

The Mojave National Preserve Conservancy is hosting a star party this Saturday, May 19. A longer post and a link to their flyer is on my other blog, My Own 100 Hikes.

Some pictures from St. Mark's

Got a thank you card and some pictures from my contact at St. Mark's. Thought I'd post a few pictures.

Since I didn't get the Coronado until after the specifics of the star party had been announced, solar viewing was not officially part of the show. However, early arrivers got to view the sun through my 60mm Coronado, and to compare those hydrogen alpha filtered views with a "white light" view through my 100ED.

My personal observation is that sunspots show more clearly (with better contrast) in white light. Still, the H-alpha view is cool. The sun was very active on April 27 (the day of our star party), and prominences were, well, prominent. There was one particularly spectacular prominence more or less due south. At least, it was to the south if I got my mirror-reversing and inverted telescopic view thing all figured out. It might have been due west!

After sunset, I took down the two solar telescopes and mounted my big C11. However, high clouds meant we were pretty limited on any deep sky possibilities. So it was the moon at sunset, Venus shortly thereafter, then Mars.

Other telescopes gave great views of Saturn. I stayed with Mars partially because I was able to give it some pretty substantial magnification. It's pretty far and pretty small, still, but larger in my C11 then either the smaller driven scopes or the many non-driven scopes could have practically provided.

The next really big outreach activity should be at the Huntington Library, on Saturday, May 26. Still waiting on details, though. I don't know if they still need me, or if they've lined up another group of amateurs.

Astronomy Outreach This Weekend

I've got two events I'll be working this weekend. On Friday, April 27, I'll be helping out at St. Mark's Lutheran School in Hacienda Heights. It's a big event, with about a half-dozen telescopes and (hopefully) hundreds of eager viewers. It's mainly a school event, but if you lived in the area and want to take a look through a telescope, that wouldn't be a problem. They'll be selling food in their lower parking lot from about 6:30pm, with telescope viewing starting at dusk. Enter from their Sonnet Place entrance (east of Vallecito Drive), on the northwest side of the campus. Vallecito splits off and to the right from Turnbull Canyon Road (you'll feel like you're staying on the "main" road when you do this), and Turnbull splits off of Los Robles, which splits off of Seventh Avenue. Google maps will give you a view of where we're talking about. Meanwhile, on Saturday, April 28, it's the regular Monrovia sidewalk Saturday. Again, from dusk 'til 9:30pm or so. On both nights, we should get plenty of Venus, moon, Mars and Saturn viewing. We might be able to try for a few "deep sky" objects from St. Marks, though probably not until later in the evening (after the crowd thins out a bit). If you go to St. Mark's, make a point of buying some food down below. It's a fundraiser for them, and we like helping them out.

March 31 Clouded Out

If you've looked out your window today (in southern California), you know we're getting clouded out today. So, sorry, no sidewalk astronomy tonight. We'll try again next month.

March 31, 2012 -- Sidewalk Astronomy in Monrovia

Corner of Myrtle and Lime, again, dusk to about 9pm, weather permitting.

Probably the last chance to see Jupiter from the sidewalk this year. That's the moderately bright "star" to the east-northeast. Higher and brighter is Venus. The crescent moon should be in their vicinity the next few nights.

Mars is the brightest "star" to the east, about half-way up the sky by the time twilight ends.

That means four possible targets this weekend. Hopefully, we'll have enough telescopes to show them all to you!

Moon, Venus and Jupiter

If you're been out after sunset the past few weeks, you've undoubtedly seen Venus and Jupiter, even if you didn't know it. Venus is the crazy bright "star" about 1/2 way up from the horizon to zenith (straight above) at sunset, to the southwest. Jupiter is the nearly-as-bright "star" about a fist-width (ten degrees) east of Venus.

On the 25th of February, the moon will be quite close to Venus, making it an even more striking sight. On the 26th, the moon will be near Jupiter.

Meanwhile, Mars is rising an hour or so after sunset. It's distinctively orange, not nearly as bright as Jupiter or Venus, but still pretty obvious, to the east, and rising higher as the night gets later.

The means on our next sidewalk astronomy night (probably on the 25th in Monrovia, corner of Myrtle and Lime), we'll definitely have the moon, Jupiter, and Venus to see. Mars may get high enough over the buildings for us to see before we call it a night.

Next month, Mars, for sure.

It's not a very favorable apparition, though, so it'll still look pretty small, even through a moderate-sized telescope.

The next sidewalk astronomy night in Monrovia will probably be in late January.
