National Sun Watching Day
Since 2019 the Royal Netherlands Association for Meteorology and Astronomy organises an annual Sun Watching Day. Observatories all over the Netherlands, both private and public, open their doors to the public to allow them to have a look at the sun through various types of telescopes. Of course these telescopes are prepared for safe viewing or even dedicated solar telescopes like the Lunt LS80THA at InFINNity Deck.
On 7 July 2019 we received 18 guests at the observatory. Weather conditions were marginal, the skies were heavily overcast, but despite that 16 of the 18 visitors were rewarded their trip with a view of the sun. The sun was around its minimum of its 11 year cycle, so not much to been seen sadly enough. I was assisted by astro-friends Roman and Caspar, the former informing visitors while I was with others in the observatory, the latter had brought a 80mm refractor with white-light filter, which was set-up in the garden next to the sundials.
On 5 July 2020 conditions looked even worse. The day before was fully overcast with plenty rain. In the morning of the Sun Watching Day itself it was still fully overcast and raining. At around 11:30am, half an hour after the first of 14 visitors arrived, the skies cleared enough to get a good glimpse of the sun. The rest of the day it stayed half overcast with plenty opportunity to have a look at the sun. This year I was assisted by astro-friends Roman and Rob. The former installed his SkyWatcher AZ-EQ6 mount with TS-Optics 100mm apochromate and white-light filter, the latter lend his Quark DayStar filter, which we mounted on a 130mm f/5 Bresser Messier Newton scope.
Again the sun was not showing much exiting details, even though a few weeks earlier I had imaged a nice couple of protuberances on it.
If you have any questions and/or remarks please let me know.
