And possible a slightly better "final" image.

Here's a time-lapse of all the "light" images with the comet circled.

Comet C/2025 A6 (Lemmon) is now receding and growing dimmer each night. I thought I'd try to capture it from the North End tonight before it disappears for 1,350 years. You could get MUCH better results from dark skies, but it's kind of fun to see that you can capture stuff like this from the city with minimal equipment. 1. In the background image, can just barely make out the comet. 2. That part of the same image blown up 3. The result after finding the comet, switching lenses, and stacking ~1500 2.5-second images representing about an hour of total exposure.

The result of stacking ~1500 2.50-second exposures. I used an Olympus micro 4/3 body and the Voigtlaender 42.5 mm / 1:0.95 Nokton lens.

The nitpicker's guide to Boston Blue Let's start with a confession: "Blue Bloods" was on for like ten years, and I never watched a single episode. But spin off a Wahlberg into a show about Boston? I'm there, riveted to the screen - along...

Amazing attention to petty detail here.

Ah, no. Just hidden on small screens.

Did google maps remove the option turn off "Labels"? There used to be a checkbox around here.

The full moon last night was about 6% larger in apparent diameter than the AVERAGE full moon. The closest perigean full moon is about 7% larger.

I had to get that off my chest because the Globe keeps reporting that a "supermoon" is 14% larger than the average.

Some more 📷

Moonrise over Logan tonight. Full moon is technically tonight, but it happens just 12 minutes before midnight. So tomorrow night's 99% illumination will be practically identical, just on the other side of sunset.

This was at 6:07pm - about 5 minutes before sunset and 12 minutes after the moon rose.

The numbers to the right of the cultivars refer to the index given during the tasting.

Toothpick dispenser and apple samples.

Pinova (1) Snow sweet (2) Thome empire (3) Ambrosia (4) Golden supreme (5) Jonathan (6) Pink lady (7) Liberty (8) McIntosh (9) Autumn crisp (10) Granny smith (11) Daybreak fuji (12) Crimson crisp (13) Cortland (14) Gala (15) Mutsu (16) Honeycrisp (17) Ruby mac (18) Mean rank 14 10 3 6 5 12 8 16 9 13 4 18 17 11 2 7 1 15 Median rank 17 10 6 5 4 9 8 16 11 15 3 18 14 7 2 13 1 12 Mode rank 18 11 6 5 10 9 4 14 17 8 3 16 13 7 2 12 1 15

Some friends hosted a fall apple tasting party today! These are the results.

Sample size: 13

Notes:
* Participants were given a scoresheet (+cheese & 7UP) and asked to rate each of 18 cultivars 1-10
* Never heard of Pinova
* I think mode is the best measure (consensus)
* Bad Honeycrisp?

Short video of the old moon rising behind Logan airport.

4/5
It's also an excellent time to observe "earthshine" - the phenomenon in which sunlight is reflected from earth back to the unlit side of the moon.

The fall equinox new moon in the morning twilight rising above Logan airport.

3/5
The fall equinox new moon in the morning twilight rising above Logan airport - 20 September, 5:20am.

This is the only time of year you can see such an old moon in the morning :)

2/5
But as the fall equinox approaches, the sun rises steeper - closer to 90°. So the sky is still relatively dark; dark enough for the faint bow of the old moon to be clearly visible.

Angle of ecliptic at sunrise at spring solstice is highly acute.

1/5
For most of the year, the sun rises at a sharply acute angle to the horizon (outside the tropics).

On the morning before a new moon, the sun is near the horizon by the time the crescent moon is a few degrees above it.

This means that the crescent is usually too dim to see in the twilight.

I witnessed the crazy mirages at Revere Beach a few years ago. Here - in 2019 - the oil house at The Graves Light appears as tall as the lighthouse.

And then the moon disappeared behind haze.

A crowd gathered. One person asked, "Ok, does anyone know what's going on? I just saw the Sun set over there (pointing east)"

The different temps of air at different layers created some weird shapes.

You can see the pocket of (warmer?) air near the water as the moon passes through.

Moonrise from Revere Beach last night looked like a glitch.

Eastern Kingbird on the Esplanade today

Sad to hear about the altercation involving our former North End ONS rep.

I only know her through my time with the Neighborhood Council and she was always responsive and professional.
