I might try to image this over the next few nights weather permitting. Thank you for the info. Terry B Armidale |

I couldn't resist some art shots of the asteroid in front of M81, even with moonlight and all: http://www.astr.ua.edu/gifimages/m81asteroid.html Somebody got asteroid all over my galaxy! Bill Keel |

Great shot Bill. Are the dropouts in the asteriod track 1) a light curve variation from the asteriod rotating or 2) an artifact from the imaging process? - Canopus56 |

Hi Bill- Very nice. Did you notice that a similar image is on SpaceWeather.com today? It was from NM, and yours from AL- a baseline of 1780 km. There is substantial parallax visible between the two images. I've taken the liberty of combining the two images into a stereo pair at http://www.cloudbait.com/science/2006vv2.html ; not too often you can do that with astronomical objects! _________________________________________________ Chris L Peterson Cloudbait Observatory http://www.cloudbait.com |

Great shot Bill. Are the dropouts in the asteriod track 1) a light curve variation from the asteriod rotating or 2) an artifact from the imaging process? - Canopus56 I did a series of 5-minute exposures (being quite pleased that our telescope's open-loop tracking lets me get away with that, since SBIG selfguiding eats a lot of time to start exposures). The gaps reflect the readout time of each exposure plus time it took me to type a filename to save each one, and typically represent 45 seconds or so. There were thin passing clouds; both the sky brightness and transparency varied noticeably between 5-minute increments, so I didn't learn anything about a light curve. In hindsight, that would have been easiest done by trailing the stars as well, but then the visual impact would be compromised. In getting those processed and aligned as soon as I got home, let me once again pay homage to Mira's image-registration tools, the best I've found. Bill |
