Solar observations: July 2018
For the month of July 2018 all Sunspot activity once again on the Sun remained extremely low.A total of 26 Observations were made for the month with the remaining days being cloud covered.This is the first time I did not see any Sunspots for the whole month though 2 very faint separate groups was observed by the 150ft Solar telescope at Mount Wilson.Most Prominences observed once again were quiet faint and small.No CMEs or Flares were seen.The total average classification value was zero. The total Relevant Sunspot Number was also 0.
Due to bad weather the first observation of the month was made on the 2nd July UT. On that day no Sunspots could be seen. A Hedgerow type Prominence was observed on the NW limb reaching a height of about 56,000km and stretched across the limb for about 205,000km. From then until the 10th no significant Prominences could be seen. All were small and quite faint. However on the 10th a faint Column type Prominence was observed on the SW limb reaching an approximate height of 102,000km.
On the 16th a double Arch Prominence was seen on the NE limb a type Fork Prominence was seen on the SE both seemed to be stronger.
A Filament was observed on the 20th and continued to be seen until the 28th as it rotated with the Sun from the east to the west. On the 29th it appeared as a Prominence on the NW limb. On that day 5 Prominences were observed, the highest on the SE reaching 65,000km. The following day those same prominences were observed much fainter with a Column type Prominence in the SW reaching a height of 93,000.
