Object Name: AR 2192
Object Type: Sunspot group
Location: Carinthia
Date: 2014-10-26
Media: Graphite pencil on white paper. Digital work done with Gimp 2
Seeing was very good at the beginning of my observation – i was able to magnify 200x. The visible details were breathtaking and I decided to sketch just the most striking part of the sunspot.
I was also able to observe and sketch a nice X2-Flare.
Clouds made it not easy to observe the enormous sunspot group AR 2192 in the Low Countries. I had only one good day to observe and sketch this marvel at ease. Thanks to good seeing conditions I could see – despite my small telescope – an impressive amount of detail. I hope the group will survive his voyage on the far side of the sun and give us another beautiful display.
Clear skies

Object: Sun
Location: Biggekerke, Netherlands (51°29’ N 3°31’ E)
Date and time: 27 October 2014, around 9.30 UT
Equipment: 8 cm refractor, Baader Herschel wedge, Solar Continuum filter
Eyepiece: 13mm Nagler T6 (79x)
Medium: white, gray and black pastel pencils, a Pierre Noire pencil and a light gray soft pastel on white printing paper, scanned, mirror reversed, contrast adjustments with Paint Shop Pro
Enormous sunspot AR2192 was one of the events lighthouse of these last days, so enormous as it was the object of several drawings of which this one, made on October 27th, 2014.
Four hours were necessary to realize it (2 hours behind the ocular + 2 hours to polish up it installed at a table).
Lunette of 102/1000 – ocular ES 6,7 mm – Prism Herchel and filter Continuum.
Total Lunar Eclipse of October 8, 2014, observed T250, Australia, north of Katherine. Nice atmosphere in the twilight moonrise partially eclipsed silhouetted against the red cliffs. This string is selected among the eight drawings, sketches showing the COLLECTED colors and visibility of lunar formations.
Full Moon déssinée the eve of the eclipse. It served as the background image for the realization of the rosary.
Sincerely

Across the Carpathian Mountains resting on the eastern Ocean of Storms is the
landmark crater of the Sea of Islands, mighty Copernicus. Copernicus is a 95
kilometer diameter complex crater that begins to show itself in all its majesty
two days past first quarter. During the time of “Snow-Ball Earth” 800 million
years ago the event that created Copernicus suddenly occurred. What remains is a
3.8 kilometer deep hummock covered flat floored, centrally peaked, terrace walled
spectacular sentinel. Especially during high sun the bright ray system of this
crater can be seen extending from the base of the glassy glacis in all directions.
The descent from the rampart to the mare floor below is about one kilometer. Three
of five peaks were clearly visible in morning sunlight. In 1999 the Clementine
near infrared camera detected magnesium iron silicates in the peaks indicating
rebound of this deep rock through the surface crust following the impact event.
To view this impressive crater all you need is a good pair of binoculars and an
opportunity between two days past first quarter and one day past last quarter.
Weather permitting, you can see it tonight.
Sketching:
For this sketch I used: black Strathmore 400 Artagain paper, 9”x 12”, white and
black Conte’pastel pencils and a blending stump.

The (Planet) Jupiter is one of the most difficult objects to observe. lt has most delicate subtle figures on surface atmosphere. Speak frankly my 13″ og showed me nothing but two main belts and 3-4 minor belts since first light the fall 2013 that not ones to surpass 12″, 8″, 6″, or 5″ED or 8″ dob at least in detail performance. Tonight’ early morning It showed me countless wrinkles on the King’s face though just at the 5-6 number of times one time was only shortest moments 2-3 seconds for 10 minutes with rated 9/10 seeing. The other interesting features were as you see [1], on the nights last autumn just near the first light night, the Europa’s color was turkish blue gray, but on this night it was pale yellow, the surface color of Europa really changed after one year ? The optical train was(is) same; flat-og-tv bino- tv nagler 7sThe [2]….. 13″ OG showed Ganymede’s contact moment with Jupiter’s limb, because the 13″ achromat’s chromatic dispersion effect of light produced weak contrast, could not identifyed the exact situation of the contact moment. For 10 minutes Ganymede moved 5280kmx0.7=3696km, the projected velocity of Ganymede is calculated as 3696km/ 600s= 6.16km/every second. # l usually write the observing date till fully to dawn as the same day .
Hi friends,
I want to introduce you one more of my drawings in high polluted sky. This time is the turn for M15. Despite of the blurred view, from the center of Madrid you can distinguish several bright stars in the center with a shape that tends to be square.

My sketch of lunar crater Clavius together with smaller craters Porter and Rutherfurd at the top of the drawing. Clavius measures 225km in diameter and is located near the southern pole of the Moon. It is named after Christophorus Clavius, a 16th century German mathematician and astronomer.
