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]

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.

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.

On the Sun you can see a large spot with the naked eye protected by eclipse glasses in the left part.

Bob, article  https://rochesterskies.org/comet-c-2023-a3-tsuchinshan-atlas/ is now updated with your beautiful pictures of the comet A3 from October 25 and October 27.

I think the very first opportunity to see C/2024 S1 (ATLAS) will come at 7:25 on the morning of October 29, when the comet will be at zero altitude on the Rochester horizon and the Sun will be about 3.5 degrees below the horizon. You might be able to see the tail rising, which should run diagonally to the right below Spica. Visibility will improve…[Read more]

Yesterday, Friday, October 25, I was briefly observing at the KR7 reservoir in the upper parking lot, which has a better view than the lower parking lot. Unfortunately, from here you can also see the light sources on the horizon and there is clear light pollution from the city. Still, it’s a good place to observe near the city. Clouds were chasing…[Read more]

I had a meeting at Assisi Heights till 8 PM tonight, actually little bit longer. After, I tried to look at West horizon, I saw  Arcturus, not Venus. I did not see comet A3 with certainty.

I hope I will go to the Root River park on Tue 10/15 to see A3 coma next to the M5, about 1 degree apart.

In the early evening, I went to Dakota Middle School. There’s a good view of the western horizon from there. On the way, I took a 50th Ave NW I noticed an unobstructed view of the western horizon in the gap between the houses so I observed from 50th Ave NW. I tried to capture the comet by camera. At about 7:10PM I saw the comet in the binocular…[Read more]

The sky situation at the beginning of the public observation at Watson Soccer Fields. Two prominent celestial lights can be seen here: Venus and Arcturus. Comet A3’s height above the horizon was about 1.7 degrees lower than Venus. It is probably obscured by clouds in this image.
Tomorrow, Saturday, October 12, comet A3 will be 3.6 degrees higher…[Read more]

After 8 p.m. I parked on 65th Street, walked to the field and took pictures of the aurora from my tripod. Suddenly I noticed a bright, almost vertical band to the west. I began to wonder what it was. For a few moments I thought it might be the tail of the now set comet A3, which has suddenly become very bright and only the tail is visible.…[Read more]

Aurora Borealis over constellation Corona Borealis above 75th ST NW

John, this is great project!

I tried to generate for the period from October 7, 2024, between 22:15 and 23:45. See attached PDF.

Here is what I found not accurate:

#1 Cannot not be visible: Mars is rising around 23:45
#6 Cannot not be visible: M8 is setting down around 22:15
#7 Cannot not be visible: M42 is rising around midnight
#9 Visible…[Read more]

Aurora Borealis just from NW Rochester backyard tonight October 7th.

I just went outside, put on my eclipse glasses and saw a big sunspot. It’s almost in the middle of the disk.

Aurora Borealis at 8:49 tonight, October 6, from 75th Street NW. Canon EOS T6, 24mm, f/2.8,ISO3200,8s.

I am thinking about Root River Park tonight, I hope I’ll make it.
