2023 Solar Viewing

Post by Christopher K. »

Solar viewing at HRPO occurs at least once per month for two hours per session. Sometimes the sessions take place by themselves; sometimes they are incorporated into a larger public event. The 2023 dates are...
21 January, 12pm to 2pm
18 February 12pm to 2pm
18 March, 12pm to 2pm
29 April, 3:15pm to 5:15pm
20 May, 12pm to 2pm
24 June, 3:30pm to 5:30pm
22 July, 1:30pm to 3:30pm
26 August, 12pm to 2pm
23 September, 12pm to 2pm
21 October, 12pm to 2pm
25 November, 12pm to 2pm
23 December, 12pm to 2pm

This may be the greatest calendar year of solar activity--sunspots, plage, flares and prominences--in most kids' lifetimes. The activity in May 2022 was over fifty percent higher than predicted by the SWPC.

Regular solar viewing was scheduled tomorrow at 12pm, but sadly that cannot take place if the rain chance is thirty percent or over. The Sun will be viewing Sunday for the purpose of determining whether a special session of solar viewing is warranted soon at HRPO.

Below is the NOAA forecast for HRPO's planned viewing time of 12pm to 2pm...
precipitation potential, 51%
sky cover, 92%
relative humidity, 82%
temperature, 13˚C
surface wind, E 23 km/h

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

There will be no viewing during this time and HRPO will close at 12:30pm. If it begins to rain anytime after 12pm, HRPO will close immediately.

The 21 January 2023 day rating is...
EXCELLENT
VERY GOOD
GOOD
FAIR
POOR
BAD
