\n<\/strong>
\nMany thanks to all those members who have sent in observations, the standard of which is very high. The main event in October was the sunspot group AR3112, which emerged around the east limb on the 1st October and remained until the 13th October. Another group very close, but to the north was AR3116 which appeared to nearly merge with AR3112 but remained a separate group because of its latitude. Overall, it was quite an active first two weeks, although after the activity appeared to become quite low with only small spot\/pore groups developing. October was a great month for observing as the weather held and allowed members to observe on most days. Activity waned during the next two weeks, but there still remained some large active areas.<\/p>\n

Prominence activity was also high, with many bright prominences and filaments to be seen throughout this month.<\/p>\n

The next event this month was the Partial Solar Eclipse which occurred on the 25th October. I put most of the pictures sent in on News and again reasonable skies allowed many to observe and send in their results.<\/p>\n

Daily observations from members are given below:<\/p>\n

1 October 22<\/strong>. AR3112 is coming over the east limb and appears to be active. AR3111 is stable as a large spot and 2 surrounding pores. AR3110, a large singular sunspot, sporting double umbrae, has developed slightly with the emergence of 2 small pores, and is followed by a small complex group AR3113. In the south-west AR3105 and AR3107 have now reached the west limb and is surrounded by faculae. A new bipolar group has developed in the south-east.<\/p>\n

2 October 22.<\/strong> AR3110 is now a much larger spot with an elongated umbra with 2 spot\/pore areas to its top. AR3113 has also increased slightly with spot\/pore groups increased in number and slightly dispersed. AR3111 has decayed slightly as it is a single spot. AR3112 has now come over the east limb and is a large, an apparently, active group. It\u2019s view may be affected by foreshortening, but none the less is surrounded by bright faculae. AR3114 is a bi-polar group to the south, and the remains of AR3107 appears as a mass of faculae to the south-west.<\/p>\n

3 October 22<\/strong>. AR3112 has now began to transit the solar disc and appears to be an active large spot\/pore group, which is surrounded by bright faculae which reaches to some activity to the north of the group. AR3111 is remains stable, while AR3114 has developed slightly from the previous day, with multiple pores and distinct umbra within the leader spot, with a further bipolar group to the west of this area. AR3113 has changed appearance with slight development in the leader spot, which now sports 3 umbrae. AR3110 has now become a chain of spot\/pores with a small spot at the top.<\/p>\n

4 October 22<\/strong>. AR3112 still the main sunspot group on the disc, with a large active region covered with spots\/pores and two main spot areas. The group appears to be elongating as it transits the disc. A separate group has emerged to the north of the area and may be associated with it (but is classed with a different AR number). AR3110 and 3113 have reached the west limb, and AR3111 is still a solitary sunspot. AR3117 has decayed, but AR3115 has remained stable. AR3114 appears to have decayed.<\/p>\n

\"22<\/a><\/p>\n

5 October 22<\/strong>. AR3112 continuing its transit across the Sun, and seems to remain fairly stable, with a large central spot with some spot\/pore leaders and a group of spot\/pore followers behind, AR3116 is a small group a little way above this larger group showing spot leader and follower with some pores in between. AR3111 is still a singular spot, while AR3113 is now on the west limb and AR3115 has now developed slightly to become a small bi-polar group with some pores in the centre.<\/p>\n

\"22<\/a><\/p>\n

6 October 22<\/strong>. AR3112 still transiting the solar disc and has slightly increased pore activity in the rear part of the group, but on the main there has not been much change. AR3116 has developed slightly also with the enlargement of the rear spot area. AR3115 has remained stable and AR3117 shows as a small pore. AR3111 remains a single sunspot.<\/p>\n

\"22<\/a><\/p>\n

7 October 22<\/strong>. AR3112 now reaching the Central Meridian, and has changed little from the previous day, and the same goes for AR3116 which still follows AR3112 to the north. AR3111 remains stable while AR3115 appears to have decayed slightly with AR3117 having decayed completely.<\/p>\n

8 October 22<\/strong>. AR3112 is in the centre of the disc but has appeared to have decayed slightly but the close proximity to AR3116 would seem that the two area may be merging. Nevertheless, the area is still large with a large spot leader with two umbrae (with minor spots preceding) and with numerous spot\/pore followers. AR3116 has two main spots with spot\/pores following the main leader spot, which appear to edge down towards AR3112. AR3119 is a new group which has just appeared. AR3118 remains stable as it transits the disc. AR3120 is a new spot which appeared on the 7th. AR3115 and AR3111 have reached the west limb. Carl Bowron and Mick Jenkins shows some magnificent activity in their images. Ian Lee shows a large amount of activity in Hydrogen-Alpha, notably the large prominence to the south.<\/p>\n

9 October 22.<\/strong> With the exception of AR3112, activity appears low. AR3112 and AR3116 now past the central meridian. On looking they appear to have merged. However, the reason they have separate AR numbers is that they have different lattitudes. AR3112 have increased activity slightly in that the rear following pores have developed, while the leader appears to be stable. AR3116 appears as a two-umbra spot leader, with surrounding pores and a spot\/pore region following. AR3120 is a small spot\/pore group preceding AR3112. AR3118 is a small bipolar group which appears stable. AR3119 has developed into a large spot showing 3 umbrae with spot\/pore leaders.<\/p>\n

10 October 22.<\/strong> AR3112 still dominates the solar disc, with a large leader spot, a double umbra spot in the centre followed by a complex group of spots\/pores, and with AR3116, showing a double umbra, above it the whole area makes a fair size group. AR3119 has developed slightly and AR3118 has decayed slightly.<\/p>\n

11 October 22<\/strong>. AR3112 and AR3116 still remain, although slightly decayed. AR3112 still has a large leader spot, but the central spots have separated into individuals. The following pores seen the previous day have lessened considerably. It is now reaching the west limb and it is notable that there appears to be a faculae stream preceding the groups. AR3119 has developed further from the previous day with a large spot following a stream of spot\/pores. The large spot appears to have a Lightbridge, or double umbra. AR3120 is now a small pore nearing the west limb. AR3118 appears to be decaying.<\/p>\n

12 October 22.<\/strong> Activity getting less. AR3112 and AR3116 have reached the west limb and AR3116 appears to have decayed to a single large spot, but AR3112 continues to remain as a large group although appears slightly decayed. AR3119 appears to remain stable and AR3118 has decayed further. New activity has appeared on the south-east limb with a pore with a large amount of faculae.<\/p>\n

\"12<\/a><\/p>\n

Image by John Chapman-Smith<\/p>\n

13 October 22.<\/strong> Activity fairly low. The main groups are now going over the west limb. AR3116 and AR3112 appear stable, whilst AR3119 appears to have decayed slightly. There are two other Ars in the east (1x 2×2) and a pore to the south-east. Surrounded by considerable faculae.<\/p>\n

14 October 22<\/strong>. Activity now low. AR3116 and AR3112 are on over the west limb, although there is a large amount of faculae still associated with them. AR3119 appears to have decayed slightly again. New area AR3121 is a small group consisting of two spot leaders and spot follower. Pore still apparent in the south transiting the disc. Another pore is apparent to the west.<\/p>\n

15 October 22.<\/strong> The solar disc is showing very little activity now that the main groups have gone over the west limb. AR3119 appears to have decayed further and only two very small singular spot\/pore groups are noticeable.<\/p>\n

16 October 22<\/strong>. Activity still very low. North. AR3119 and 3123 (newly formed?) have reached the west limb. New group AR3122 is a new bipolar group. South. 1 new group (as yet un-numbered) has developed in the south consisting of spot\/pores.<\/p>\n

18 October 22.<\/strong> Activity continuing to be very low. Only AR3124 remains as a medium spot group now reaching the west limb. The new AR seen on the 17th (AR3125) remains as a small, relatively faint, spot\/pore group. Nevertheless, Carl Bowron shows that in H-alpha the activity may be quite high, especially prominence activity.<\/p>\n

19 October 22<\/strong>. Activity very low. AR3124 now on the west limb still as bipolar group but surrounded by faculae. AR3125 appears to have decayed somewhat, now is just a pore. A new group has emerged to the south-east, again consisting of spots\/pores.<\/p>\n

21 October 22<\/strong>. 1140UT. Activity still very low. 2 groups AR3126 and AR3127 are spot\/pore groups near to the central meridian. AR3126 is the biggest. Another pore is visible in the west with some faculae preceding (arrowed). Some faculae on the west limb may indicate some activity.<\/p>\n

22 October 22.<\/strong> Activity very low, but groups have all developed slightly. AR3125 has developed into a singular spot approaching the west limb. AR3126 has become more of a bipolar spot\/pore group, whilst AR3127 has grown very slightly into a small spot\/pore group. Carl Bowron shows some great prominence activity.<\/p>\n

24 October 22<\/strong>. 1308UT. Activity at present constantly low, although AR3126 has developed slightly and AR3130 is shown as a bipolar spot\/pore group. A new spot has come over the east limb.<\/p>\n

25 October 22<\/strong>. Partial Solar Eclipse<\/em>. Activity still very low. AR3126 appears to have developed slightly but is nearing the west limb. 2 small spot\/pore groups (one marked AR3130) just past the central meridian, and new spot AR3131 has now rounded the east limb and appears to be a singular spot. Weather not the best but many observed partial solar eclipse. Carl Bowron has very good images of white light activity. Ian Lee shows that activity was high again in Hydrogen Alpha with a magnificent prominence to the south.<\/p>\n

26 October 22.<\/strong> AR3131 has come around the east limb with another region AR3133. 3131 is a large singular spot with sizeable penumbra, whilst AR3133 is a small spot\/pore group. AR3132 is a single pore whereas AR3130 is a small slightly complex group, with a double umbra spot leader with several spot and pore followers. AR3126 has reached the west limb and appears to be a double spot shrouded with faculae. Cliff Meredith\u2019s image shows the activity quite well.<\/p>\n
