The next planned public solar viewing session at the Highland Road Park Observatory will be on Saturday 26 June from 3:30pm to 5:30pm. At this time the sunspot at AR2833 is nice and sharp with a near-round shape.

HRPO's next planned solar viewing session will be on Saturday 14 August from 12pm to 2pm.

The Sun is blank today, but take a picture if you want one with no spots! A new sunspot should be rotating into view within the next seventy-two hours.

There is a some moderate surface activity accompanying five Active Regions!

Current view:

I saw ARs 2871 and 2872 easily. I did not see 2873, 2874 or 2875. I sketched it the solar surface at HRPO between 3pm and 3:15pm CDT using one of HRPO's Orion 6" Dobsonian at 48x (25mm Sirius Plossl). Any who have the ability and interest should view this area within the next forty-eight hours.

There will be a Solar Viewing Special Session on Saturday 25 September from 12:15pm to 2:15pm at HRPO. There is no admission fee and all ages are welcome.

AR 2877 has no appreciable visible phenomena at this time. AR 2878 shows two distinct sunspot development areas.

AR 2882 is a whopper, with a clearly defined penumbra. AR 2883 seems to be mostly plage. AR 2884 has a single small yet quite dark spot; there is some plage several degrees of longitude over, but I don't know if that is part of the declared active region.

I sketched AR 2882 today at about 2:40pm. I saw the asymmetrical umbra clearly at 48x; I saw the one small and two tiny spots near it as well.

HRPO will be offering extra solar viewing sessions during the time slots of the live NASA broadcasts of the Lucy science mission briefings...
*Wednesday 13 October, 12pm to 1pm
*Thursday 14 October, 12pm to 1pm
*Thursday 14 October, 2pm to 3pm

Anyone with the ability to do so should view AR 2882 within the next forty-eight hours...
