It’s hard to believe: we’re now just one short weekend away from the big ticket astronomical event for 2017, as a total solar eclipse is set to cross over the contiguous United States on Monday, August 21st.
Celestial mechanics is a sure thing in this Universe, a certainty along with death and taxes that you can bet on. There are a few key question marks come eclipse day, however, something that we can only speak with a few intelligent assumptions out 72 hours out.

Live on the wrong continent to witness the August 21st total solar eclipse? Well… celestial mechanics has a little consolation prize for Old World observers, with a partial lunar eclipse on the night of Monday into Tuesday, August 7/8th.

A new comet discovery crept up on us this past weekend, one that should be visible for northern hemisphere observers soon.
The discovery: We’re talking about Comet C/2017 O1 ASAS-SN, a long period comet currently visiting the inner solar system.

ASTROTECH SPACE OPERATIONS/KENNEDY SPACE CENTER, FL – The last of NASA’s next generation Tracking and Data Relay Satellites (TRDS) designed to relay critical science data and research observations gathered by the International Space Station (ISS), Hubble and dozens of Earth-orbiting Earth science missions is undergoing final prelaunch clean room preparations on the Florida Space Coast while targeting an early August launch – even as the agency reviews the scheduling impact of a weekend closeout incident that damaged a key component.

An angry monster lurks in the shoulder of the Hunter. We’re talking about the Red Giant star Betelgeuse, Alpha Orionis in the constellation Orion. Recently, the Atacama Large Millimeter Array (ALMA) gave us an amazing view of Betelgeuse, one of the very few stars resolved as anything more than a point of light.

Had your fill of binocular comets? Turns out, 2017 may have saved the best for last. The past few months has seen a steady stream of dirty snowball visitations to the inner solar system, both short term periodic and long term hyperbolic. First let’s run through the cometary roll call for the first part of the year: 41P Tuttle-Giacobini-Kresák, 2P/Encke, 45P Honda-Markov-Padjudašáková, C/2015 ER61 PanSTARRS and finally, the latecomer to the party, C/2017 E4 Lovejoy.
Next up is a comet with a much easier to pronounce (and type) name, at least to the English-speaking tongue: C/2015 V2 Johnson.

Have you been following the Springtime parade of bright comets? Thus far, the Oort cloud has offered up several fine binocular comets, including Comet 2/P Encke, 41/P Tuttle-Giacobini-Kresak, 45/P Honda-Mrkos-Pajdusakova, C/2016 U1 NEOWISE and C/2017 E4 Lovejoy. Now, another comet joins the dawn ranks, as it brightens up ahead of expectations: 2015 ER61 PanSTARRS.
