Periodically, viewing of the Sun takes place at HRPO. Weather permitting, three different methods are used...
*indirect projection onto white viewing surface. Patrons get a sense of the speed of Earth’s rotation as they see the Sun’s image slide on or off the projection device.
*safely-filtered optical light sent through standard telescope. This option allows patrons to spy sunspots both small and large.
*hydrogen-alpha wavelength. Flares and prominences are seen easily in this wavelength.

More information:

The next solar viewing session scheduled at the Highland Road Park Observatory is Saturday 31 January from 12pm to 2pm.

The next solar viewing session at HRPO is 28 February. It will be noted that the solar viewing schedule has been tweaked to reflect the different times HRPO personnel use each instrument.

This is the NOAA forecast for 11am tomorrow...
precipitation potential, 8%
sky cover, 33%
relative humidity, 63%
temperature, 9˚C
surface wind, E 16 km/h


If the above forecast holds there will be moderate skies for sungazing.

The next solar viewing session at HRPO will take place during the NanoDays celebration on Saturday 28 March. Weather permitting, these are the instruments to be used...
2:30pm to 2:45pm, Learning Technologies Sunspotter
2:45pm to 3:15pm, Orion 10" Dobsonian Reflecting Telescope
3:15pm to 4:30pm, Coronado 90mm SolarMax II Hydrogen-Alpha Telescope

As usual, adult patrons will be able to purchase solar viewers at two dollars each.

The next solar viewing session will take place during the International Astronomy Day celebration on Saturday the 25th. The viewing session will last from 3pm to 5pm, when the Sun begins to sink behind the trees.

Although IAD was very fun, unhappily there was little to no Sun.

The next solar viewing session will take place at the Highland Road Park Observatory on Saturday the 30th from 12pm to 2pm.

The next solar viewing session is scheduled during ARRL Field Day this upcoming Saturday, from 2pm to 4pm. If the skies are clear there is a good chance of sunspot and flare activity. There has been a severe (level 4) geomagnetic storm in the past twenty-four hours, and another predicted for the rest of the day.

Due to the fifty-percent chance of rain, HRPO personnel will attempt solar viewing only from 2pm to 2:30pm. However, the entire span of ARRL Field Day (until 10pm) will be open to the public as rain does not hinder that operation. Hope to see you at HRPO sometime today!

NOAA is reporting a Level 2 geomagnetic storm in the past twenty-four hours, another predicted G2 for the rest of the day, and yet another predicted one for tomorrow. All of this is due to a coronal mass ejection which just missed the Earth.

I looked at the Sun about twenty-five minutes ago with a 1x solar viewer. The largest Active Region at this time, 2411, is much too small to be seen with no magnification. I'll try the Sunspotter tomorrow.

The next public solar viewing time will be Saturday, 26 September at HRPO from 12pm to 2pm.

At 3:51pm I sketched the Sun with the Sunspotter. I saw and noted ARs 2414 (which is reported to have quadrupled in size since yesterday) and 2415. However, I believe I will now do a standard clipboard sketch with predrawn circle next time I use the Sunspotter. Reaching inside with a pencil was very awkward and the device has lost a foot cushion, causing it to wobble!

Yesterday, a stream of solar wind and a minor coronal mass ejection hit Earth. NOAA is predicting a Level 2 geomagnetic storm for the rest of the day, and a G1 for tomorrow.

The next public solar viewing time will be on Saturday, 26 September from 12pm to 2pm at HRPO.
