In the past twenty-four hours (as of this posting) there was an R3 alert from the Space Weather Prediction Center. According to Tony Phillips there was a shortwave radio blackout over southeast Asia. Simultaneously, there are four Active Regions visible on the Earth♁-facing side of the Sun☉. Together these locations are generating over a dozen sunspots and areas of plage, much of which has been visually confirmed with equipment at the Highland Road Park Observatory. Due to these conditions, HRPO has programmed a special viewing session. A Sunspotter projection device, a six-inch Orion Skyquest Dobsonian and a hydrogen-alpha tube will be utilized. Please tell your family, friends and coworkers.
It can be very damaging to eyesight to view the Sun☉ in an incorrect manner. Please follow all rules given by on-site personnel.
[The next regular monthly solar viewing session will be during International Astronomy Day on 7 May, but there is no guarantee the same amount of activity will be present on the Sun☉.]
