With the transit of Mercury on Monday a reminder on how to view the Sun safely is in order. I have posted on this subject many times in the past and maintain a full post on the various techniques one can use to safely view the Sun.
Since Mercury is quite small you will want a bit of magnification to view the event properly. If you do not have a good solar filter for your telescope come to a local event where telescopes are available.
On Hawaiʻi island you can either go to the W. M. Keck Observatory HQ in Waimea or Subaru Observatory HQ in Hilo. Both observatories are hosting transit events at dawn Monday morning 11 Nov, 2019.
These events start at 6am with webcasts of the transit from other observatories further east, with the Sun rising far enough to see the transit from 7-8am.
