Mars, Uranus and the Pleiades
This image with the planets
Mars
and
Uranus near
the
Pleiades star
cluster, all in the constellation
Taurus, was captured on
July 16, 2024, from Carranza Field in Wharton
State Forest, NJ. The two planets were at formal
conjunction in
geocentric right ascension on July 15 at 5 am EDT and were at
their apparent closest to each other (appulse) at 10:28 am EDT,
32 arc minutes (0.53°) apart, but clouds precluded observing
yesterday morning. Since then, Mars has moved eastward (down and to the
left in this view) at a faster rate then Uranus. As a result of that
differential rate, and regardless of their current proximity, Uranus
reaches
opposition on November 16, 2024, but Mars won't until
January 15, 2025.
The stars labeled in the
upper right quadrant of the image (mouseover for labels)
were guides in recent years for finding Uranus quickly with
binoculars. Around 3:30 am, Mars (magnitude 0.9),
Jupiter (-2.1) and
Saturn
(0.9) were
visible with unaided eyes, while Uranus (5.8) and
Neptune (7.9) were visible
with 8x42 binoculars, despite the hazy sky. So, five of the
seven non-Earth planets were visible. Mercury and Venus are
visible after sunset now.
This snapshot, looking roughly east-northeast at 16 to 22°
altitude, is from a single raw frame taken at 3:22 am EDT with a
Canon EOS RP DSLM and a Canon 200 mm, f/2.8L telephoto lens on a
fixed tripod. It was exposed 2 seconds at f/2.8, ISO 6400,
tungsten white balance. Modest processing was applied with Canon's
Digital Photo Professional 4. It was not cropped yielding a
field 10.2° wide x 6.8° high.
Astronomical twilight would begin at 3:48 am.
Here's the alignment on July 19, 2024 (same exposure
settings).
Fire in the Pines
On
July 10, 2024, after
afternoon clearing at home, I went to Carranza Field in Wharton
State Forest, NJ, to look at comet
13P/Olbers in a darker sky. There was a fire in that area
that made the news the previous week, closing the nearby
Batona Trail and Campground, but I thought it was now
history. The main sand road to the field, across from the
monument, had no warning/prohibition signs that I could see, but
100 yd farther down Carranza Rd at the Batona trail, I saw some
blue barrels at the entrance, so I drove down for a look. The
barrels had signs indicating the Batona Trail was closed to Rt
532, but it looked like someone had pushed the barrels out of
the way, so I took that route back to the field(this is little
more than a skinny, sand two-track, but it has few dips, unlike the
main road;
here's a picture of it
snow-covered in January 2024).
Going down the trail, I saw a small patch of flames just off the
side of the trail/road, but when I got to the field itself,
there was blue smoke wafting over the western end, and as I
rounded the southwest corner, I could see some substantial
flames in the trees to the south. There was no firefighting in
progress.
This snapshot of those flames was taken at 8:40 pm, twelve
minutes after sunset, with a handheld iPhone 11. It was exposed
1/30 second at f/1.8, ISO 800. The only processing was a slight
adjustment of the color balance.

A warning: With the recent hot, dry
weather, and likely truck traffic from firefighters when they
were active, the sand road passing the campground became really
sugary. My RAV4 groaned a little on the way in with the default
4WD setting, but on the way out, I used the "sand" setting and
it passed through with aplomb. I'd be concerned about trying to
drive a non-4WD/AWD vehicle through it.
BTW, the astronomical viewing was a bust as clouds had moved in
by time it got dark, so 13P was out of the question. I did see a
nice crescent Moon early on, and around 9:40 pm, I noticed a
bright satellite pass intermittently through cloud openings,
moving from the SW to the NE. Back at home, I checked
Heavens-Above and it was the ISS as I suspected, peaking at 72°
altitude, magnitude -3.6.
The Crescent Moon
& Mercury
On
July 7, 2024, the
2.1-day-old, 4.6% illuminated
Crescent Moon was 2.8°
above the planet
Mercury at
9:18 pm EDT when this image of them was captured from Collins
Lane Park in Maple Shade, NJ. Taken with a Canon RP DSLM camera
and a Canon 400 mm, f/5.6L telephoto lens on a fixed tripod. It
was automatically exposed 1/25 second at f/5.6 , ISO 12,800
using 4800 K white balance (the directly illuminated crescent is
greatly overexposed). The only processing was a little
boost in Mercury's brightness, and cropping this portrait
orientation to a 3:4 ratio for a field about 3.2° wide x 4.2°
high. Mouseover for labels.
The Young Crescent Moon
On
July 6, 2024, I went to
Bishops Gate in Mt Laurel, NJ, to look for the planets Venus & Mercury, comet
13P/Olbers and the young
Crescent Moon. New Moon
was on July 5 at 6:57 pm EDT, so at sunset on July 6, 8:32 pm,
it would be 25 hr 35 min old. Arriving a little late, I spotted
Venus just
above the distant treetops at 8:44 pm with 12x50 binoculars. One
minute later with the 12x50s, I found the sublimely thin lunar crescent
4½° above Venus when it was just 25 hr 48 min old and 1.3%
illuminated. At 8:56 pm, I spotted
Mercury with the 12x50s about 10° from the Moon at
the 10 o'clock position. As twilight deepened (but thin clouds
were increasing), I found comet
13P/Olbers at 9:37 pm with my
35x115 spotting scope. In the meantime, I checked Corona
Borealis with the 12x50s; I could see all the stars that make up
the constellation's semi-circular stick figure, but there was no
sign of the recurrent nova, T CrB.
This snapshot of the thin crescent was taken at 9:04 pm when the
Moon was 26 hr
07 min old and 4.8° altitude, afocally through one eyepiece of the bino viewer on the 35x115
spotter using a handheld iPhone 11. It was exposed 1/30 second
at f/1.8, ISO 800. The only processing was cropping and a slight
adjustment of the color balance.
Thompson's Beach
On
July 1, 2024, I went to the parking lot of the
nature observation platform at Thompson's Beach, NJ, on the
north shore of the Delaware Bay, about 2 miles east of East
Point and the Maurice River Cove. My primary objective was to
spot Venus, Mercury and comet 13P/Olbers, and to follow-up on
the recurrent nova, T Coronae Borealis. These observations were
successful, starting with Venus at 8:29 pm EDT, a minute before
sunset. Before that, and continuing during twilight, I used my
Swarovski 115 mm (4.5 inch) spotting scope with the 35x
binocular eyepiece module to observe the Osprey over the marsh
on the west side of the parking lot. Ten adults (five pairs)
were seen, including a pair at the nest in the picture above
(plus a chick in the nest) about 100 yd away. They were a
splendid view in the scope. The birds are evidently accustomed
to nearby humans as I could periodically see the adults closing
they eyelids to take a nap. I discovered they (the adult and the
chick) defecate the same as the Bald Eagles (adult and
fledgling) back home in their nest on the cell phone tower at
the Pennsauken Country Club (link at the top of the page).
This snapshot of the scene, looking west-southwest, was taken at 8:30 pm with a handheld
iPhone 11. The scope's objective is to the right, with the
sliding lens hood extended, The ribbed section near the middle
is the focuser (it focuses like a typical telephoto camera
lens). The 35x binocular eyepiece module is at the left end. I
also have a 30 to 70x zoom eyepiece module (they attach via a
bayonet mount) . The top of the this module includes a forehead
rest and a short aiming tube (which I don't often use,
especially after dark). Dangling below is the lens cover (mouseover
for a view from the rear). The scope is mounted on a Foto-Pro
gimbal head, the vertical arm of which can be tilted for better
access to high elevations. As shown, it's at the 45° setting, so
I can tilt the scope enough to observe the zenith. The mount
sits on a heavy-duty Benro carbon fiber tripod.
The Moon and a pair of Moon Dogs
On
June 20, 2024, I went to the field at Bishops
Gate in Mt Laurel, NJ, to look for comet
13P/Olbers.
Unfortunately, clouds along the northwestern horizon foiled that
attempt, but about 10:30 pm EDT, as I sat under the open
hatch at the back of my car facing southeast, I saw the
nearly-full
Moon
(it would be full at 9:08 pm on June 21). Then I noticed a
Moon Dog
(paraselene)
in a cloud to the right of the Moon. Shortly after, as another cloud
moved into position, a second Moon Dog appeared on the left, so
a pair of Moon Dogs (paraselenae) flanked the Moon, 22° on
either side (checked with an
outstretched thumb and little finger). Mouseover for labels.
This snapshot of them was captured at 10:34 pm with an iPhone 11
handheld while resting atop my spotting scope, which in turn was
locked in place via its mount on a tripod. The EXIF data
indicated it was exposed 1/2 second at f/1.8, ISO 1000 (although
the exposure period was clearly longer than 1/2 second). Except
for size reduction, no processing was applied or
adjustments made. The turquoise dot left of the greatly
overexposed Moon is an internal camera reflection.
The star well above and a little left of the Moon is second
magnitude Sabik (Eta Oph). To the right of the Moon, and a
little higher in the contrail shadow, is first magnitude Antares
(Alpha Sco).
At the time, the Moon was 14.6 days old, 99% illuminated, 18.3°
altitude, 158° azimuth (SSE) in the very southern part of the
constellation
Ophiuchus (just east of a line between M19 and M62).
The Moon's ecliptic latitude was –5.4°, about as far
south as it gets, so it would transit (12:13 am on June 21) at
just 21.7° altitude for this nominal 40°N-75°W location.
