Here is the final look at the NOAA forecast for the planned solar viewing period of 2:30pm to 4:30pm...
precipitation potential, 78%
sky cover, 74%
relative humidity, 76%
temperature, 30˚C
heat index, 36˚ C
surface wind, NW 7 km/h


Danko's Clear Dark Sky states that during HRPO's viewing time the transparency rating will be "too cloudy to forecast" (0 out of 5) and the seeing rating will be "good" (4 out of 5).

The Sky Rating for this viewing period is...
EXCELLENT
VERY GOOD
GOOD
FAIR
POOR
BAD

Don't despair! The American Radio Relay League Field Day will still take place at this time--rain or shine! There will be a Radio Transmission Planet Walk at 3pm for the kids. A City Gelato cart will also be here; bring money.

The next regularly-scheduled solar viewing time at the Highland Road Park Observatory will be Saturday 29 July from 12pm to 2pm. As usual, weather permitting there will be the Sunspotter, 10" Orion Skyquest and Corono Solar Max II. We're headed toward minimum, but remember there was that quite large sunspot complex a few days ago.

At 1:40pm CDT the Sun left Gemini and entered Cancer. Tony Phillips says today's Sunspot Number is zero.

Between 2:15pm and 2:30pm I viewed Sun. I did this due to a G1 alert issued by the SWPC for the rest of the day, and due to four Active Regions currently on the Sun.

I saw easily the components of 2674 (with amazing transition zones), 2673 and 2675; I saw also the “plage” of 2672. This was all in HRPO's Orion Skyquest Dobsonian with factory filter.

This very nice collection of activity on the Earthward size of the Sun warrants the programming of viewing time for interested members of the public. The Highland Road Park Observatory will have a special Solar Viewing Special Session from 12pm to 2pm on Saturday 2 September. Here is the current NOAA forecast for that time...
precipitation potential, 13%
sky cover, 48%
relative humidity, 61%
temperature, 31˚C
heat index, 35˚ C
surface wind, NE 5 km/h

Danko's Clear Dark Sky states that during HRPO's viewing time the transparency rating will be "below average" (2 out of 5) and the seeing rating will be "excellent" (5 out of 5).

The Sky Rating for this viewing period is...
EXCELLENT
VERY GOOD
GOOD
FAIR
POOR
BAD

Though HRPO regularly has solar viewers for sale during solar viewing, none will be available as they were all sold out for the Great American Eclipse.

Between 12:30pm and 12:45pm I viewed and sketched Sun. I did this due to a G3 alert issued by the SWPC for the rest of the day and tomorro, and due to six Active Regions currently on the Sun.

Some of these sunspots group have developed rapidly. ARs 2673 and (especially) 2674 had a wealth of transition zones. 2674 had a very dark kidney-shaped spot. AR 2678 was also visible. It is strongly encouraged that anyone with the means to do so safely view this activity by Sunday.

The Highland Road Park Observatory will have another special Solar Viewing Special Session, this time from 12pm to 2pm on Saturday 9 September.

Between 10:15am and 10:30am I viewed and sketched Sun. I did this due to a G1 alert issued by the SWPC earlier in the day, and due to an Active Region currently on the Sun. The activity was minor.

48x yielded a good view of 2680 with its transition zone; I was just able to spy the accompanying small spot closer to the center of the solar disk. Anyone with the means and interest to do so safely view this activity within the next twenty-four hours. Sadly, conditions are not predicted to be favorable during that time period.

The Highland Road Park Observatory's next regularly-scheduled solar viewing session is from 12pm to 2pm on Saturday 30 September.

Between 1:25pm and 1:30pm I viewed the Sun. I did this due to a G1 alert issued by the SWPC for tomorrow (and a G2 alert for Wednesday), and due to an Active Region currently on the Sun. The activity was minor.

48x in the Orion Skyquest 10" yielded a fair view of Active Region 2685; I saw the transition zone only with the best tweaking of focus. Anyone with the means and interest to do so safely should view this activity within the next forty-eight hours. This is NOAA's prediction for conditions at 10am CDT tomorrow...
precipitation potential, 1%
sky cover, 1%
relative humidity, 56%
temperature, 18˚C
surface wind, N 18 km/h

Danko's Clear Dark Sky states that during HRPO's viewing time the transparency rating will be "above average" (4 out of 5) and the seeing rating will be "poor" (2 out of 5). If these predictions hold, the sky rating will be EXCELLENT.

The Highland Road Park Observatory's next regularly-scheduled solar viewing session is from 12pm to 2pm on Saturday 11 November.

Between 12:45pm and 12:50pm I viewed and sketched the Sun. I did this due to another Active Region rotating into view. The activity was minor.

48x yielded a very good view of 2685 and 2686; I saw the 2685 transition zone easily and the two main components of 2686, even though those components are very close together and still rotating into view. I even spotted most of 2686’s associated plage! Anyone with the means and interest to do so safely should view this activity within the next seventy-two hours. This is NOAA's prediction for conditions at 10am CDT tomorrow...
precipitation potential, 0%
sky cover, 0%
relative humidity, 44%
temperature, 14˚C
surface wind, NW 18 km/h

Danko's Clear Dark Sky states that during HRPO's viewing time the transparency rating will be "above average" (4 out of 5) and the seeing rating will be "average" (3 out of 5). If these predictions hold, the sky rating will be EXCELLENT.

Between 2:15pm and 2:45pm I viewed and sketched the Sun. I did this due to an Active Region rotating into view. The activity was minor.

48x yielded a good view of 2689; I saw the transition zone fairly easily, as well as the bend in the main area. I saw the smaller spot nearby. Anyone with the means and interest to do so safely should view this activity within the next twenty-four hours. Danko's Clear Dark Sky states that tomorrow from 9am to 3pm the transparency rating will be "above average" (4 out of 5) and the seeing rating will be "good" (4 out of 5). This is NOAA's prediction for conditions at 11am CDT tomorrow...
precipitation potential, 0%
sky cover, 13%
relative humidity, 63%
temperature, 19˚C
surface wind, SE 10 km/h

If these predictions hold, the sky rating will be EXCELLENT.
