A very large sunspot group that was responsible for a large solar flare in the last
few days has crossed the Sun's meridian and is now headed toward the limb, so I was
able to get a pic of it before it disappeared by the end of this week.

Comet 12P/Pons-Brooks is moving rapidly across the sky from northern Pisces to Aries
and brightening until early April. I used a zoom lens set at 120 mm to focus
on the area below Triangulum (below as seen from 38° north latitude in the early
evening).

This evening, despite the full Moon, which will undergo a penumbral eclipse
later tonight, we have a nice view of three planets arrayed along the ecliptic,
Mercury, Jupiter, and Uranus. However we're also treated to a bonus of
Comet 12P/Pons-Brooks coming in from the right toward α Arietis, or Hamal,
later in the month.

Mercury is at the height of a nice evening apparition at which it stands almost
vertically above the Sun's position after sunset, so even though it attains only
around 17° elongation, it is quite prominent. For the first time, we
can see Jupiter in the same field of a wide angle lens.

I tried out the intervalometer on my new D5000 with a 35mm lens to see if I
could get a filtered Sun sequence in preparation for the eclipse in April.
This shot was at ISO 3200, 1/1000" exposure, and f/11. It should
be good at these settings to catch the entire eclipse from start to finish.

Following several days of rain, we were treated to a beautifully clear evening
with a one day old crescent Moon ~ could my Celestron C-90 offer up a good image
even without tracking the Moon's motion? I was also long overdue for getting
a picture of Jupiter as it moved eastward through Aries.

After finally figuring out how to attach my Nikon cameras to my Celestron C-90
(an orange tube version from the 1970's or early 1980's, which has a focal length
of 1,000 mm operating at f/11), I got a shot of the Sun on the afternoon of March
7 to see what the image scale will be if I use it for the eclipse.
