June's meeting
Our June meeting will be our annual Summer BBQ. Plan on working up an appetite by
helping to set-up and get the charcoal going at about 5:30pm. We will start eating
around 6:00pm.
The club will provide hamburgers, hotdogs and vegetarian black bean burgers,
along with a variety of toppings. If you wish, provide side dishes for your family, but not
to be shared with members because of COVID.
December's meeting
This month is our Holiday dinner. We'll be opening the doors at 6:30 to set up the tables
and chairs, and then the feast will begin at 7:00 PM. TVS will provide the drinks and
paper/plasticware. In addition we will provide the main course for this month's
holiday celebration, possibly turkey and/or tri-tip. Members are asked to bring a dish to share,
and of course bring family and friends to share in the festivities. Based on the first letter of your
last name members are asked to bring a dish to share:
A-D Macaroni, Potato, Green or Fruit Salad
E-J Vegetable or Beans
K-O Appetizer
P-Z Dessert
H2O Open House
Our next open house is May 25, 2024 for the club's dark sky site,
Hidden Hill Observatory,
aka H2O.
Anyone can come to our open houses, not just club members; but you cannot go
there without an escort. We will meet at the corner of Mines and Tesla Roads
at 6:00 PM, then caravan to the site on a drive that takes about 50 minutes.
The admission is $3/car; please bring the exact amount. There is no gas on
the way, so be sure to gas up before leaving. The site is essentially in the
wilderness, so there is no electricity and water, and there are only a couple
of pit toilets. Cell-phone reception is iffy at best. While there is a
picnic table there, you really should bring your own chair. If you need to
see what you are doing, bring a red LED flashlight, not a white-light
flashlight. And use masking tape over your car door and interior lights, or
pull the fuse. If you don't have a scope, you can always find someone who is
willing to let you look through theirs. And don't forget to bring your
binoculars. Expect to stay until about midnight and get back to Livermore at
around 1:00 AM.
