*'ELECTION DAY ASTEROID' MISSES EARTH:* Asteroid 2018 VP1
<https://en.wikipedia.org/wiki/2018_VP1> approached Earth on Nov. 2nd
... and missed. The 3-meter wide space rock had a 1 in 240 (0.41%)
chance of hitting our planet on the eve of US Election Day, but no
fireballs or impact-infrasounds

were detected. Break out the Oreos
<https://www.cnet.com/news/oreo-tucked-its-cookies-into-an-asteroid-proof-doomsday-vault/>
and let the election begin!
*ANOTHER BIG SUNSPOT:* A new sunspot, potentially a large one, is
rotating into view over the sun's southeastern limb. Its leading dark
core is inset in this magnetic map from NASA's Solar Dynamics Observatory:

The +/- polarity of the sunspot marks it as a member of Solar Cycle 25.
This comes as no surprise. Almost every sunspot this year has belonged
to the new solar cycle

Seasons are changing on the sun, and today's sunspot is the latest sign
of increasing activity.
