    Default Asteroid questing



    My quest continues to catch and sketch all of the first 100 asteroids discovered. On Monday night I tracked down two more with my XT8.

    41 Daphne is in Aquarius, about mag 12 which is close to limiting magnitude from my urban rooftop. While sketching the field, I was distracted by a couple of bogies in the form of geosynchonous satellites of about mag 10 or 11. Somewhat fascinating to watch those sit still while the stars run past. I needed 120x to pick up Daphne.

    93 Minerva is in Pisces, predicted about mag 11.7 but seemed somewhat brighter, easily seen with 75x.

    Tuesday night was clouded out, but luckily tonight cleared out again. I caught the 'roids to sketch their B positions. Minerva had nearly twice the sky motion of Daphne, being closer to us and faster.

    Only 13 remaining of the first 100 left to catch. Three of those 13 are coming to opposition this month, will keep me busy soon.

    Thanks for reading, clear skies!

    Nice Ray! I haven't had too much scope time recently. I've had better luck in the early mornings between 5:00 am and 5:45 am when the skies have been clear. Evenings mostly have been foggy.

    Wow, only 13 of 100 remaining. Quite a good performance. I like the sketches too, nice and functional.
    I have followed one, one or two weeks, years ago. That was all. To me it is actually almost a new sport within the hobby! Very nice!
    Thanks for reminding me to give more attention to it in future.

    Hi Ray. I have been following your great asteroid catches and sketches for some time now, but, I did not realize that you are within 13 of the first 100 asteroids discovered. Congratulations on grabbing 41 Daphne and 93 Minerva. And, I also like your A-B annotations in the star fields to show the asteroids motion. Thanks for sharing these with us on here Ray, and the best of wishes on grabbing the last 13 asteroids.

    Looking at the minorplanet.info ephemeris, I realized two more asteroids were just past opposition. 66 Maja and 83 Beatrix are in Pisces, less than 5° apart. Both are about mag 12 and starting to fade. I wanted to catch them while still visible from my rooftop. I could see almost none of the Pisces stars naked eye, so I star-hopped over from Aries. Both asteroids were easily visible with the 7mm DeLite. I used 16mm ES to sketch wider fields.

    In between the asteroids was a bonus. Last year, I had made a finder chart for Van Maanen 2, which is the "closest known solitary white dwarf", 13.9 light years away. It's just 7' from a 5.7 mag star, HIP 3765. At 12.4 mag, was a bit fainter than my asteroids. Again the 7mm DeLite did the trick, even caught a nearby 12.7 mag star.

    I plan to do outreach from the Chabot deck tomorrow night. During a lull, I will go for B positions of the 'roids.

    Wonderful asteroid sighting and tracking, Ray!

    Hope to do a "B" sighting of Vesta sometime soon, maybe this weekend.

    On my rooftop with the XT8 the last two nights, caught another new pair of asteroids of the "first 100".

    46 Hestia is in Pisces, about mag 10.9. Starhopped from η Psc, one of the few Pisces stars I can detect naked eye. First catch was right next to 11th mag star, had to wait awhile for them to separate to verify which was which.

    87 Sylvia is in Taurus, about mag 11.9. Starhopped from the Pleiades. Both 'roids are near opposition.

    So I'm up to 91 of the first 100 asteroids tracked and sketched, 134 in all over the last four years.

    Clear skies!
