    Macastronomer started the topic January 31st Eagle Bluff parking lot is available in the forum Star Parties 1 year, 5 months ago

    The parking lot is available both Friday and Saturday (January 31st, 2025) at Eagle Bluff.

    I may or may not attend. Sky-wise, tonight looks okay, Thursday looks even better except for some wisps around midnight—then the transparency gets bad Friday evening and eventually clouds start to roll in around 2-3AM. Saturday looks like a wash t…[Read more]

    Macastronomer started the topic January 31st Eagle Bluff in the forum Star Parties 1 year, 5 months ago

    I reached out to Eagle Bluff, but I just found out our contact is out of the office. I’m awaiting a response after leaving a message.

    It is the New Moon this Friday. I’m not sure I can make it. Cloud-wise is also iffy. Currently it says clear all day Friday with clouds rolling in by 3AM on Saturday and transparency not good after 3PM on Friday. I…[Read more]

    That’s great that it was fought on their security camera. If it had been several feet into the grass, I wonder if it would have been noticed!

    Who all is up for a Messier Marathon on March 28th or 29th? If the sky is clear, and Eagle Bluff is available… I would like to get it on the calendar.

    If Eagle Bluff isn’t available, is there another location that would work? We’d need some pretty good horizons.

    Here is the amazing orbital motion of Comet/2024G3 around the sun as seen by the C3 coronagraph on SOHO

    On close inspection of the above mentioned cell phone pics they are of the C/2023 A3 comet and NOT C/2024 G3. (Bummer!)

    I was out in and north of Root River Park and had a good view of the setting sun.  I observed for an hour but was unable to see the comet with the naked eye or with my 10×50 binoculars however I did capture a cell phone image of it (I just looked now at the images!).  I’ll put them in the next post.

    Josef Chlachula replied to the topic 2025 Observing in the forum General Discussion 1 year, 6 months ago

    Today January 14 I observed comet C/2024 G3 ATLAS after sunset. I was observing over the KR7 reservoir, alternately photographing and observing with the binocular 10×50. Around 5:25pm I suddenly saw the comet in the reds low over the horizon in my 10×50. It had a bright nucleus and a distinct tail. I observed it for about 10 seconds. Then I looked…[Read more]

    Maybe 4:45 to 5 pm today we’ll get a chance to see the comet?

    C/2024 G3 is still intact in SOHO C3 images from today.

    Sungrazing Comet ATLAS (C/2024 G3) has just entered the field of view of SOHO’s C3 coronagraph (see image below).  Should be great viewing of the comet’s fiery passage near the sun.

    Monday or Tuesday 1/13 and 1/14 could be sunny and comet C/2024 G3 could be visible on day sky. On Monday above Sun, so Sun could be blocked by roof,  on Tuesday comet will be on the left side of the Sun, so Sun could be blocked by the vertical wall on the right side.

    Petr Horálek in Europe was able to take a picture of the comet C/2024 G3 ATLAS. Not only that, he saw this comet with the naked eye. Let’s hope for good weather, we should be able to see it as well.

    fealeybob14 replied to the topic 2024 Observing in the forum General Discussion 1 year, 7 months ago

    Our Reflector magazine for December 2024 has a cover topic “A FLYING SAUCER IN CETUS”.  I wondered if this might  be referring to the near edge on galaxy NGC 1055 that I noticed when observing and photographing M77.  Sure enough!  On page 5 and 6, NGC 1055 is pictured and described by author Dr. James R. Dire as looking like a flying sau…[Read more]

    Glorious M42 (Orion Nebula) returns to our skies!  The image below is the first one taken with my 6 inch Quattro f/4 reflector of M42 as one can tell from the spikes on the brighter stars due to the secondary mirror supports.  82, 5 second frames were stacked and contrast stretched.

    Josef Chlachula replied to the topic 2025 Astronomical League Observing Challenge in the forum General Discussion 1 year, 7 months ago

    Great idea. We should include some featured objects into our public events, for example M42 (Orion Nebula) or C14 (Double cluster).
    Hubble imaged 87 of the 110 objects in the Charles Messier catalog and 89 of the 109 objects in the Caldwell catalog. So there is 87+89 = 176 potential objects to observe and compare with the Hubble images.
