2019 Solar Viewing

Post by Christopher K. » January 2nd, 2019, 1:08 pm

The first planned public viewing of the Sun at the Highland Road Park Observatory will be from 12pm to 2pm on Saturday 19 January. It is not yet known what the sunspot production will be this coming year, although the Sun is in solar minimum. Sixty of 2018 was spotless, though there were at least twenty-two geomagnetic storm alerts.

This is currently weak surface activity in the form of Active Region 2732, which is will soon rotate around to the back of the Sun (if it makes it to the limb). Between 2:00pm and 2:05pm I did not see anything at 120x, though I scanned every limb.

Here is a current image...

Below is the NOAA forecast for HRPO's viewing time of 12pm to 2pm...
precipitation potential, 7%
sky cover, 80%
relative humidity, 72%
temperature, 17˚C
surface wind, W 29 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 "bad" (1 out of 5). HRPO personnel will still attempt viewing of the Sun, but please keep in mind the conditions.

The 19 January 2019 daytime rating is...
EXCELLENT
VERY GOOD
GOOD
FAIR
POOR
BAD

All solar viewing sessions include a free tour of the two domes, and solar-powered machines.

There is currently Active Region 2733 on the Sun. I looked about eight minutes ago with HRPO's 10" Orion Dobsonian reflector at 48x. I had a rather "fuzzy" view; perhaps I didn't let the tube acclimate enough. I encourage anyone with the ability to view this AR within the next twenty-four hours.

Since the beginning of winter, not counting special events such as the Eclipse or Plus Nights (and not counting tonight), HRPO has had to cancel a cumulative total of twenty hours of sky viewing due to a BAD rating.

Therefore, there will be a Contingency Sky Viewing session on Tuesday 19 March from 10:30am to 12:30pm. As usual, there is no admission fee and the event is for all ages.

At 5:18pm CDT, there were areas labeled 2735 and 2736 on Tony Phillip's site, each with visible dark spots. The 2736 label is gone now, but the action is still here...

On this first full day of Spring, there are two Active Regions--2735 and 2736. From 2:52pm to 3:00pm CDT today, I sketched the Sun using BREC's Orion Skyquest Dobsonian 10" at 48x. I saw five medium and seven small dark parts of 2736; I did not see 2735.

I encourage any with the appropriate equipment to view this activity within the next forty-eight hours.
