I was delighted this morning to find this dark and large filament at the north-eastern limb of our Sun. It had the appearance of a large serpent with foot like projections anchoring it to the solar surface and then visible curving around the limb. The filament is magnetic curtains of plasma hovering over the Sun’s surface, this an especially large and detailed one. I read on the Spaceweather site that the length of the filament would measure the distance from the Earth to the Moon. That’s one big serpent!

I went out to sketch the AR 2339 in h-alpha but when I saw this massive Hedgerow type prominence on the limb it had to be done.

Eyes turned to the sky early this morning on Maui for the shortest total lunar eclipse of the 21st Century. This is due to the Moon passing through the edge of the umbra instead of the center where the circular diameter of the Earths shadow would be widest. The maximum time for totality (when the Moon passes into the umbra) can be up to 1 hour 40 minutes so the umbral portion lasting only a little more than 4 minutes is a short one. The time of partial eclipse this morning made for a beautiful transition across the lunar surface of darkness and then totality. As I always see a rabbit in the Moon I thought maybe the Easter Rabbit Moon has a lot to do getting all those eggs hidden and no time for a long performance, though it was still a great show!
This is a 7×50 binocular view sketch during totality. The Rabbit in the Moon appears to be flying a kite asterism which seemed fitting for the spring occasion of the season.

For those that observe and sketch the Moon, trying to pick targets just before, just at and just after first quarter can be much fun because there are so many choices in good relief. On this occasion I chose two large walled plain craters near the terminator. Albategnius (129 km.) the younger of the two ancient craters and further from the terminator it was displaying its central peak (1.5km. tall) and large crater Klein (44 km.) on its rim. Crater Halley (36 km.) to the northeast is notably a kilometer deeper than Klein and although further from the terminator has a completely shadowed floor with that greater depth.
The other large crater Ptolemaeus (154km.) was on the terminator at the beginning of my sketch.
With the sun so low the rim shadows were long and were creating a special effect. In combination with the rim shadow of little crater Ammonius (8.5 km.) I could see old Nesse. Jim Adlhoch describes the floor shadow as looking like the head and neck of the Loch Ness monster- see Lunar Photo of the Day September 4, 2014.
Crater Ptolemaeus has a floor covered with many shallow bowl shaped craters, ghosts buried under lava. These ghost craters can be seen at low sun but the central peak is completely absent. To the north is crater Herschel (41 km.) with a shadowed floor.
For this sketch I used: Black Canson sketching paper, 10”x10”, white and black Conte’ pastel pencils and blending stumps.

Living in Eastbourne, I am lucky enough to have the famous cliffs at the end of the South Downs close by; the panoramic views they afford are ideal for watching sunrises and sunsets, which are frequently rendered even more beautiful by dramatic coastal clouds. On Sunday 18th January I was driving back from a visit to the beach further east at Normans Bay, when I noticed a break opening up in the blanket of cloud to the west. Instead of heading home I made the short detour up to Beachy Head, where I was treated to this wonderfully picturesque celestial scene.
Best regards and clear skies, Oli
