We amateur astronomers have it easier than most at being able to pursue our hobby during the pandemic. Ours is often a solitary endeavor. With access to the dark site, or with a dark enough backyard, we can keep on going when the weather allows. 

What of those new to the hobby though? If you’re one of them, welcome again. Quite a few of you are interested in astro-imaging, and more and more, this club is getting you covered—check out last month's novice talk. Also appreciated is all the good astro-info available “in person” at the monthly Zoom meetings: novice, general membership, and special interest group. You can also find the website library of recorded presentations to sample at leisure. 

But what about those of you who joined because you wanted to look up, wanted a guide to help you, and then got hit with the pandemic? 

TentSkies.PNGThe day after the state parks reopened, a new member and I took a trip to some of the darkest skies we have in Texas at Colorado Bend State Park, just 4.5 hours away. It’s a gorgeous park, and a good way to hedge your bets. If you come for the skies and get clouded out, you won’t be disappointed by the springs, falls and caves to explore by day. Social distancing is observed by all and masks are worn in line at the chemical toilet restrooms with sanitizer... click read more button

Summer begins in earnest in July, with high daytime temps and matching levels of humidity. This might discourage some from outdoor activities, but July is one of the best months of the year for astronomy.

Shallow Sky Object of the Month: A Trio of Double Stars in Lyra

Original article appears in GuideStar July, 2020.

By Bill Pellerin

Originally Published in the July 2016 Guidestar

Lyra.jpg

Object: Three double stars
Class: Stars
Constellation: Lyra, the Lyre (musical instrument)
Magnitude: See text
R.A.: 18 h, 50 m, 24 s (constellation)
Dec: 36° 49’ 12”
Size/Spectral: See text
Distance: 150 ly
Optics needed: Unaided eye, binoculars, and a small telescope

It’s now officially summer, as of June 20. The Sun has traveled as far north as it’s going to go this year and is beginning its long trek back south toward the winter solstice (December 21). It seems so far away now. While the hours of daylight are getting fewer now, it’ll take some time before we see significantly earlier sunsets.

Daylight saving time doesn’t help (don’t get me started on this topic). Amateur astronomers are obliged to wait later into the night (clock time) to view their favorite objects and the buzzing of the mosquitoes does not facilitate a relaxing observing session. Bug spray, anyone?

July 2020 Challenge Object NGC 6210 Plus a Bonus Southern Object

July Challenge Object

by Stephen Jones

NGC6210.jpgNGC-6210 Planetary Neb in Hercules
The Turtle Nebula
RA 16h44m30s Dec +23deg 48.0’
Size 48”x30” Vmag 8.8
 
NGC 6210 was discovered in 1827 by the famous double star observer F.G.W. Struve.  Its estimated distance from Earth is estimated at around 6500 light years, though distances to planetary nebulae tend to be rather uncertain.  It is a small object, particularly if you haven’t studied planetary nebulae much.  However, it is very bright.  It should be easily visible at just about any power, with most telescopes. 

July 2020 Messier of the Month

Messier of The Month

July 2020

By: Jim King

This is a series of columns primarily revolving around observing the Messier Catalogue.  The intent is to provide the reader a small sampling of the Messier objects each month that are most visible in the time frame the column is published.  Hence, these deep sky objects should be easily identifiable in and around the month of July.  Some months may have a special treat in addition to the Messier Objects.  Check the trailer. 

Asterisms: The Teaspoon and The Lemon in Sagittarius

Asterism: a grouping of stars that form a recognizable pattern.
Constellation: Sagittarius  
Right Ascension: 19 h, 04 m
Declination: -24º 44’
Magnitude:  Naked eye
Size: 8o x 4o

TheLemon.PNGIn the constellation Sagittarius, the Teapot, there are two asterisms that share common stars: The Lemon and The Spoon. These asterisms comprise the line of stars to the “upper left” of the Teapot, attached to the “handle” of the Teapot.




 
 
 
 
   
The “Lemon” is thSagittarius.PNGe lower 3 stars: Pi π, Omicron ο and Xi ξ. 
 







TheTeaspoon.PNGThe “Spoon” includes the “Lemon” with 2 additional stars at the top. Starting with the “highest star”, they are: Rho ρ, 43 Sgr, Pi π, Omicron ο and Xi ξ.
 
 
 
 
 
Since the Teapot’s spout is spewing steam or hot water creating the Milky Way, you need a Teaspoon to put the Lemon in your tea.

Mars’s Latest Visitor: NASA’s Perseverance Rover

David Prosper

NASA’s latest Mars rover, Perseverance, is launching later this month!  This amazing robot explorer will scout the surface of Mars for possible signs of ancient life and collect soil samples for return to Earth by future missions. It will even carry the first off-planet helicopter: Integrity. Not coincidentally, Perseverance will be on its way to the red planet just as Mars dramatically increases in brightness and visibility to eager stargazers as our planets race towards their closest approach in October of this year.  

100 Her—A Matching Double Star

by Bill Pellerin

Originally published in the July 2015 Guidestar

Star 100 Hercules

Object: 100 Her, SAO 85753, STF2280
Class: Double Star
Magnitude: 5.8, 5.8, combined 5.79
R.A.:  18 h, 07 m, 50 s
Dec:  26 degrees, 05 minutes, 51 seconds
Distance:  230 ly
Constellation:  Hercules
Spectral: Matching A3V stars
Optics needed: Small Telescope

Why this object is interesting:

One of the challenges of double stars is figuring out what catalog they’re in, what their catalog number is, and what catalog numbers are represented on my map (paper or computer). SkyTools lists eleven catalog designations for this star. TheSky recognizes 100 Her by at least three designations. You should be able to find it by one of the designations given here, and if that fails, you can find it by its RA and DEC.

Note: The August, 2007 GuideStar has another double star in Hercules, 95 Her.

Astronomy at HAS is for All

Joe Khalaf, HAS President

Since before taking over as the president of H.A.S. in January, I've had a strong focus on making our hobby and our club accessible and inclusive to anyone who had a desire to explore astronomy. That was a goal I laid out for our club when I became the Outreach chairperson and it's never been more true than it is now. As a minority and a person of color myself, some of the most fulfilling experiences I've had in astronomy and in life were when we brought our telescopes to traditionally underserved and underrepresented minority communities and had a chance to interact with our visitors, with exploration and discovery being the common bond that brought us together those evenings.

The events we've seen on TV recently with the killing of George Floyd have been horrific, and point to a broader and more systemic problem in our society. However, I'd be naive to state it cannot exist in our local astronomy clubs. Though I have never experienced it at H.A.S. or any other local club myself, I have experienced it in other places outside of astronomy. And I do recognize that my experiences alone do not encompass the collective experiences of anyone who has been a member in the past or today.

While I cannot speak for the broader collective of clubs in the Houston area or the hobby in general, let me state this, unequivocally, for our club - RACISM AND OTHER FORMS OF DISCRIMINATION OR BIGOTRY HAVE NO PLACE IN THE HOUSTON ASTRONOMICAL SOCIETY, AND AS LONG AS I AM PRESIDENT AND CAN DO SOMETHING ABOUT IT, IT WILL NOT BE TOLERATED HERE. As is the case with anyone who feels they've experienced racism or discrimination, they can come to me in confidence so that we can address the problem. There's no reason to suffer this alone or to feel isolated from the club because of it. If there is something more systemic in our club that I'm unaware of, please let me know and we will tackle it at the leadership level.

Science is not devoid of racism and bigotry. There are too many examples of discrimination based on race, religion, gender, and other identifiers that many qualified scientists deal with on a daily basis. It wasn't too long ago when the issues of widespread sexual harassment by Berkley astronomer Geoffrey Marcy came to light, after decades of simmering under the surface and complaints being swept under the rug. Countless similar examples of racism exist in the same academic and scientific settings. But acknowledging them isn't enough. We must do all we can to eliminate all forms of racism, discrimination, and bigotry wherever we can.

The heavens above are there for the enjoyment of all humankind, and our club's mission is to make sure that anyone - regardless of race, color, creed, religion, national origin, sexual orientation, or gender identity, can find safety and comfort in exploring this hobby without discrimination. We will always strive to make the Houston Astronomical Society not just a place of inclusion for all of our members, but one where everyone is treated equally. Not only is this my mission, but I can speak for the rest of the executive leadership and the board in saying it's theirs, as well.

If anyone has any comments or concerns, please address them directly to me, [email protected], and I'd be happy to discuss them further with you. In the meantime, let us all strive to be kind to one another and to do our small part to make the world a better place, one person and one organization at a time.
