My name is Bob Moler, I am an amateur astronomer who’s been observing the heavens for over 60 years. I’m currently living near Traverse City Michigan.  I have no special training, nor have ever taken an astronomy course for credit.  However I’ve taught college level 101 astronomy courses. I’ve had astronomy related radio programs on Interlochen Public Radio since 1974, and have produced the current Ephemeris program since 1975.

This blog contains mainly, the transcripts of those radio programs, plus other posts.

GTAS LogoI’m a founding member of the Grand Traverse Astronomical Society, which was established in 1982, and am currently the society’s newsletter editor.  We generally meet on the first Friday of the month at Northwestern Michigan College’s Joseph H. Rogers Observatory.  All are welcome free of charge.  The society’s website (www.gtastro.org) has information and our outreach schedule.  We have at least seven monthly star parties at the Sleeping Bear Dunes National Lakeshore (April to October) each year, plus 30+ events elsewhere in the region.

ssa-badgeI’ve also become a NASA/JPL Solar System Ambassador as of January 2014.  So I am available to talk to groups and schools about space and astronomical topics.  Contact me via http://www2.jpl.nasa.gov/ambassador/profiles/Bob_Moler.htm or use the contact form below.

However opinions expressed on this blog are my own and not that of NASA or JPL.

    Hello Bob Moler,

    You are looking at big stars in the skies, but missed the little one in the “message” field: the name and email are marked with stars obligatory field [Required fields are marked *] while the message itself is not obligatory. Very funny 

    First time on your website. You seem to providing valuable information, but 1/8 (and 1/9) entries are NOTABLY missing, such as when the Tucson shooting occurred. The whole reason I came to your website is to find the Orion position for those days. May I ask why you did not make any comments on those days? Or to put it in other way: where was Orion on those days in relation to Tucson, Washington D.C., London and other important points? Would appreciate your response.

      Ephemeris is a week day program, so I have posts Monday through Friday. So there are no Ephemeris posts on the weekend.

    Bob, I did not expect to write any immediate follow up, but I see that my message was posted online awaiting moderation as if there was any forum. Moreover, my name and email address were pre-typed in the appropriate fields in case I would want to write another email – or in case I will come back to the website so it would recognize me, correct? What for? That’s very bad idea, Bob! I am using public computers and ignoring millions of Americans who do the same is always insulting. I do not see how to remove my name and email from your fields and I assumed that my message is strictly private. If not, please manually delete my name and email.

      First posts by commenters are held as pending for review. Once approved, and yours were, you should not have any delays in the future.
      I also delete comments with URLs that point to commercial sites especially astrological and sex sites.
