late October 2013



rare hybrid solar eclipse on
Sunday, November 3

(Earth & Sky)
in US, only east-coast viewers
get a glimpse,
at sunrise & just after

in Durham, sunrise is 6:43 am;
partial eclipse ends at 7:08 am;
(remember this is the 1st day of
non-daylight-savings-time)
28% of the sun's diameter
will be covered at sunrise

similar eclipse timings/predictions
for other US cities



how to find comet ISON:
(it still requires a telescope;
on 10/31/13 it was m = 8.5,
about as bright as Neptune...
and brightening by about
0.1 magnitude per day....

work by the 2nd week of November?)
