ASTRO: 09-22-09 Aurora
Big and bright but mostly featureless. What features I do see are
moving very fast. I only have my wife's simple camera she uses for her business and it is not suited for this type of photography. I've reduced them mainly due to high noise content. Note what little features you see in the second and third images has moved considerably yet they were taken as close together as the camera allows (about 15 seconds as I somehow turned on the delay feature and can't figure out how to turn it off. That's Cassiopeia in the first images upper left) and the handle of the big dipper in the last one. I couldn't find the tripod so had to prop it up on the deck meaning I couldn't point it very high up. At one time the aurora extended to within about 30 degrees of the southern horizon but had retreated greatly by the time of the first shot which is pointed at about 80 degrees azimuth (0 north) Rick -- Correct domain name is arvig and it is net not com. Prefix is correct. Third character is a zero rather than a capital "Oh". |

It would be nice to have such advance notice of these events. |

It would be nice to have such advance notice of these events. I do photometric work for a professional astronomer who wants dates in the year/month/day format. Sometimes this is the result. My brain doesn't switch as easily as it did a half century ago. Rick -- Correct domain name is arvig and it is net not com. Prefix is correct. Third character is a zero rather than a capital "Oh". |
