244P/2000 Y3

  • 244P/2000 Y3 (Scotti) This is the first discovery image of my very first comet "Scotti" (all the other earlier "discoveries" turned out to be of known objects....). Here is a 2nd image (note the shift against the crowded starfield). Here is a 3rd image.

    Images with the Spacewatch telescope and CCD

    As a team member with the Spacewatch survey for Near Earth Asteroids (NEA's) and other populations of solar system objects, I observe on Kitt Peak in Arizona typically for 8 nights each lunation. I am able to use some of my observing time to observe some of the many available comets within the range of our 36 inch telescope or 1.8-m telescope and CCD camera. The following images are just some of the comet images I've obtained or helped obtain over the years

    Photographic comet images

    Comet Hyakutake over Mission San Xavier del Bac

    This image was obtained as the moon set in the west on the night that comet Hyakutake was closest to the north pole. The yellow cast on the usually white Mission is due to local lighting.

    Comet artwork

    Sonoran Hyakutake

    This painting was made more than a month before comet Hyakutake would have reached the position on the sky depicted in this painting. I was a bit optomistic about just how the comet was to appear as it set into the twilight sky in the west behind Mission San Xavier del Bac near Tucson in Arizona. Unfortunately, the comet was not quite this spectacular as it sort of "fizzled" as it moved inside of Earth's orbit. 


    This painting is of a bright comet in the twilight sky behind a lighthouse on the ocean shore. In particular the lighthouse is the Heceta Head lighthouse on the Oregon coast, USA.

    The background image is comet P/Shoemaker-Levy 9 as it appeared on 1993 March 30, a few days after discovery. This image was obtained with the Spacewatch telescope and shows all the major structures that were seen in this comet.
