For the month of June 2018 all Sunspot activity once again on the Sun remained extremely low.
A total of 16 observations were made for the month with the remaining 14 days being cloud covered and/or rain.
A total of only 2 groups were observed. This included 2 groups in the north and nil in the south, comprising of 11 spots in the north and 0 in the south giving a total of 11 Sunspots.
The average Relevant Sunspot number for the month was 8 and the average CV was 8.9 and the Q CV 2
No Coronal Mass Ejections (CMEs) were observed.
Due to bad weather the first observation of the month was made on the 3rd June UT. On that day no Sunspots could be seen. A mound type Prominence was observed on the NE limb reaching a height of about 37,000km. On the SE limb a small active Prominence was also seen.
No further observations were made until the 6th due once again to bad weather. No Sunspots or any other activity could be seen on that day. Again due to bad weather no observations were made until the 10th when a Hedgerow Prominence was observed on the NW limb reaching a height of about 37,000km. On the NE limb a single arch Prominence could also be seen.
On12 June a new single Axx sunspot could be seen close to the NE limb in AR12713 while on the SW limb an active curved type pillar Prominence was seen reaching a height of approximately 84,000km. The following day the same Prominence on the SW limb reached a height of about 140,000km.
The small group in AR1273 now became a CV (Classification Value) Bxo (2).
No further Sunspots could be seen from the 15th to the 16th when bad weather prevented any observations until the 21st. The group in AR12713 had reappeared on that day with a CV of Dso (25) and a further new group with a CV of Dsi (28) was also observed in AR12715. Both these groups remained on the solar disc until the 24th when a large Filament was seen
By 27 June the solar disc was clear of all Sunspots for the rest of the month and on the 30th no activity could be seen at all.
No Flares were seen for the whole month of observations.
