Fireflies and Constellations

Fireflies in Southold


Surrounding Custer Observatory is a large field owned by the Town of South. In the last few weeks there has been a noticeable burst of activity in the field at dusk! Thousands of Fire Flies are in flight across the field at dusk looking for a mate! I am new to observing Fire Flies although I remember them from childhood. I never gave them the closer look that they deserved after capturing them and putting them in a jar. My only goal at that time was to watch the blinking of their soft light in the dark. 

I recently became aware of a reported decline in our Fire Fly population and a Citizen Science project to keep track of Fire Fly populations across the United States. Seeing a friend, Steve Bellavia, post a photo of this night-time flurry of activity reminded me of the Citizen Science project and thought I should add the Custer location to the map of this project.

On subsequent nights I decided to try my hand at more night-time photography and photograph the soft light of the night-time flight of these fascinating childhood insects. At the same time I decided to catch some and put them in a large jar, something I have not done since I was young, only this time it was in the interest of science! I brought them indoors to photograph them and try to identify the species based on a photo ID page on on the Museum of Science's Firefly Watch website. According to their photos I had caught a Photorus firefly.

These fireflies produce a green light. In the sky is the constellation Scorpius and the straight blinking line in the sky is an airplane.

The Custer dome was rotating at the time of this timed exposure, a happy accident, so the dome opening appears larger then it is.

Transit of Venus from California


At California's Griffith Observatory

to witness the Transit of Venus


On June 5, 2012, thousands of people were at the Griffith Observatory, which is located in Los Angeles, CA., to view a once-in-a-lifetime event! People were there to witness Venus as it passed between earth and our Sun! There were many amateur astronomers sharing their telescopes, equipped with solar filters, with the public. The solar filters allow you to view the sun safely in order to get a close-up view of the TOV without the sun damaging your eyes! (You should never look directly at the sun without the proper protection to avoid permanent eye damage!)

There were many news crews and helicopters documenting the event. The Observatory is on top of a mountain overlooking the Hollywood Sign and had monitors and screens throughout the Observatory showing the Transit in real time through video feeds. 

OBSERVATORY OFFERS PUBLIC VIEWING OF TRANSIT OF VENUS On Tuesday, June 5, Griffith Observatory welcomed thousands of people for a once-in-a-lifetime free viewing of the transit of Venus. Observatory staff, along with volunteers from the Los Angeles Astronomical Society, Los Angeles Sidewalk Astronomers, and The Planetary Society, offered visitors the chance to look through filtered telescopes, the coelostat, and Observatory eclipse glasses. Tens of thousands of people from around the world watched the Observatory's live video feed of images from its Zeiss telescope and coelostat and commentary from curatorial staff. ~ Griffith Observatory
