ACA Club Messier Marathon
March 25, Saturday at 7:00 PM, at NMR-DSO
Moon rise-set: 0453-1619

In the year 2017, New Moon will occur on March 28, thus providing a good opportunity
for a Messier Marathon on both the weekends of March 25/26, 2017 (primary)
as well as April 1/2, 2017 (secondary option).
On the primary date (March 25/26),
there will be a good opportunity to attempt to hunt down all Messier Objects in one night
from suitable mid-northern latitude locations, while the second date will be
a tough challenge for the evening objects, M74 and M77.
According to Tom Polakis' investigation,
on the first primary occasion, a full score of 110 Messier Objects
should be possible from locations between 12 deg and 37 deg Northern Latitude
with most difficult object M30 in the morning, and southern limit from M110,
while on the secondary date in April, the limits will be 20 deg to 41 deg North.
M74 and M110 will limit to the south, M30 to the north; it will just be around these days
of the year that M74 will become invisible for its annual conjunction with the Sun.

Messier Objects Everywhere!

Rest up this afternoon, so you are ready for an evening sky, full of wonders.

Please arrive before dark.
Park with your headlights toward the road.
Bring what you have of planisphere, binoculars, telescope, towel to lay on, Messier list.
Wear socks, shoes, long pants, layered clothing.

Please eat ahead or bring a snack.

from the abundance of knowledge, skill, and enthusiasm
at our local meetings and star parties.
