Event

We will be doing a solar observing program.  Telescopes will be set up to observe the photosphere (using a solar safe white light filter) and chromosphere (H-alpha telescopes).  We will also talk about the solar cycle, sunspots, the magnetic field, what the sun looks like with differrent filters.  We'll also go over what happens during an eclipse and what solar structures we can see during totality. 

Date: Monday, April 1, 2024

Time: 11 a.m. - 12:15 p.m. Pacific

Event Report

Comments and anecdotes about the event:
AOH volunteers did a solar observing day using a telescope with a white light solar filter to show the photosphere (sunspots), and a hydrogen-alpha telescopes to look at the chromosphere (prominences, filaments,and plage). We also talked about the solar cycle, magnetic fields, and about the upcoming solar eclipse. We used the magnetic sun poster to show the photosphere, chromosphere, and corona. We also had a photo of 2017 solar eclipse during totality and showed them the prominences in the chromosphere and the glow of the corona. The sun was quiet so it was a challenge finding the lone sunspot. The students got to appreciate that while the photosphere appeared to be quiet, the chromosphere was quite active We were able to put the Magnetic Sun model of the sun to good use and showed them that sunspots have a north and south pole. We also used the model to show how filaments and prominences are tethered to the sun.
