The Sun 30-4-08

April 30, 2008 Leave a comment

Just totalled up the months observations and I managed to get a record on 24 days in April which is highly unusual! Normally I am lucky if a get to see some sun on 10 days of the month. It must be the fact that daylight hours have extended so I can do observations before and after work. In the dark days of last winter I recall I struggled to observe on more than 4 days in a month when the sun was consistently low in the sky and shrouded in grey murk.

Today there was a really fine quiescent curtain/hedge prom on the south west limb which was starting to look more active and change shape in the late afternoon. Elsewhere most of the proms are on the west limb again. The main filament group is disappearing over the south west limb. The plage region in the west is looking much quieter today with a single slender arcing filament bisecting the plage.

Took ages to get the basic sketch record completed today through holes in the cloud. Not much surface detail in the photos due to a thin milky cloud layer reducing the seeing although the proms show up well. The east limb is still quiet while a parade of small arch proms can be seen arcing over the west limb. The main filament group is nearing the south west limb while the plage region in the north west quadrant remains active.

Today seemed like deja vu with cloud and rain in the morning and a clear sunny afternoon. The same extended to the sun where the east limb was very quiet again and only small quiescent proms generally visible in the north south and west. On the surface the filament group seen yesterday was less prominent and was initially split into one long and two short lengths. These then merged into two main filaments that almost joined each other in the south west quadrant. The main active area had three small curved plage spots and very thin short filaments following the outer edges of the plage.

Awful grey morning with showers and wind then at 5pm it suddenly cleared in the west and I snatched a look. I was pleased to see a large arch prom on the south limb, some filaments and an active region in the north west quadrant.

Two long filaments have been active and very visible on the sun the last two days. Region 991 came and went without developing much in the space of a day while 992 lingers but is now fading. The afocal image below captures the main two filaments, two areas of brighter plage and small prominences in the north and west.

New solar cycle 24 Active Region forming on the sun

April 12, 2008 Leave a comment
The first active region of solar cycle 24 was observed on January 4th 2008. This new active region in the north displays the characteristic reversed polarity. The bright region has not coalesced into a sunspot yet and may fade without properly forming, we will have to wait and see! Very little activity was otherwise observed today, there are some small prominences in the north with the larger group of proms lying quite close to the new active region.

The Moon and the Pleiades 8-4-08

The Moon passed close to the Pleiades star cluster tonight in a conjunction. I caught it quite late due to cloud and just had time for a quick 2 second photo with the Canon S3 IS at ISO 80. Even at 2 seconds the stars are trailing!
