We had one like that when I was living in Morocco. We had driven from Rabat
to Casablanca to see it, and were sitting on a terrace drinking beer when it
happened.
I call them nebular eclipses.

Hi Bill and all,
The weather forecast for the eclipse was correct. The weather was rotten:
the eclipse here was obscured by clouds. The loss of light from the eclipse
was not any different from a darker patch of clouds. However, I was able to
observe the eclipse. At the time of the eclipse maximum, the clouds did
clear enough to see that the eclipse was in progress in progress. See
attached photo. No optical aids like pin hole cameras, binocular projections
etc were required. The sun was barely visible to the naked eye through the
clouds. There were no opportunities to explore an eclipse sundial like the
one you proposed for San Mateo (San Francisco). I hope others had clearer
skies.
The picture was taken at 6:17 pm PDST. The times listed below are standard
time, an hour earlier so the picture shows the eclipse maximum in Victoria
BC.
Regards, Roger bailey

Hello again,
Thanks Bill. Your note alerted me to check further and to prepare for
observations. I did some checking based on your note and now see this
is something to look forward to. The eclipse will be fairly
significant even if I am north of the center line. I will set up a
system to observe and photograph the event but cloud and rain is
forecast for Sunday after a week of summer sunshine.

Hello Sundialists,
Here is a link to a new type of paper sundial made specifically for
the partial solar eclipse viewed from San Mateo, California this Sunday.
You need a simple pin-hole projector (a card with a small hole in
it) to use it.

use)
If anyone will be in the area at that time, I would love to hear if
it works, and see a photo of it in use if possible. The math was
more challenging than I expected.
I plan to talk a little bit about this project at the NASS meeting
this summer in Asheville, NC.
-Bill
