January 7th, 2014: Robo-AO is at the 223rd meeting of the American Astronomical Society in Washington DC with 2 talks and 5 posters that used Robo-AO data or technology:
December 17th, 2013: We have submitted for publication the results of the first season of the Robo-AO Kepler Planetary Candidate Survey. This study represents the largest single adaptive optics survey to date and is just the beginning of our goal to observe every Kepler planet candidate host star to search for blended nearby stars, which may be physically associated companions and/or responsible for transit false positives.
The 53 Kepler planet candidates resolved into multiple stars by Robo-AO, 44 of which are new discoveries.
October 25th, 2013: We completed another 5-night observing run covering 800 additional observations including an intensive nightly campaign to monitor Comet ISON. The Robo-AO team also welcomes its newest graduate student, Gina Duggan, who will bring the Robo-AO infrared camera online next year and lead initial science observations.
Summer 2013: This summer sees a diaspora in Robo-AO leadership: Principal Investigator Christoph Baranec and Project Scientist Nicholas Law started faculty positons at the Institute for Astronomy at the University of Hawai'i at Manoa and at the Department of Physics and Astronomy at the University of North Carolina at Chapel Hill repectively. Both will continue working with the Robo-AO system and data. In the meantime, Reed Riddle will take over Robo-AO operations at Palomar Observatory.
August 21st, 2013: This marks the end of the Robo-AO summer observing season with the automated odometer well past 9000 observations! This weekend, Christoph (and Nick via remote) will be following up many of the Robo-AO discoveries from this past run with the Keck laser adaptive optics system for further infrared characterization and Robo-AO will be lending its main science camera to CHIMERA next week. We also have a new time-lapse video of the laser captured from a camera bolted to the Robo-AO electronics rack: it shows the laser and sky from the telescope's point of view.

August 16th, 2013: During the middle of our August observing run, Jerome Ballesta (Imagine Optic) assisted summer student Mee on using a HASO wavefront sensor to calibrate the non-common path errors between the laser wavefront sensor and science camera. After implementing the calibration the peak intensity of the final images on the visible have increased by 10% to 60%, depending on seeing conditions, and appear more symmetric in shape.

July 24th, 2013: The Robo-AO team is in the middle of our first 10-night observing run. Although we lost several nights due to ash and humidity, the remaining nights are shaping up to be good. We've also just switched over to using Kristina's automated target selection system which will increase our observing efficiency over the course of each night.

June 19th, 2013: The Robo-AO team welcomes its newest student members: Chatarin "Mee" Wong-u-railertkun (Caltech) and Rachel Thorp (Caltech). Mee will be developing several methods to improve the non-common path calibration of the adaptive optics system and Rachel will be working with Jean-Michel Désert on using Robo-AO to study the impact of stellar multiplicity on the properties and occurrence rates of planets.
May 19th, 2013: Robo-AO PI, Christoph Baranec, presented results of the Robo-AO/Kepler KOI imaging campaign at the first TESS (Transiting Exoplanet Survey Satellite) science meeting at MIT. Robo-AO will be crucial to validating planetary candidates identified by the TESS mission which may be more numerous by an order of magnitude than those identified by Kepler.
April 20th, 2013: Shortly before sunset on our sixth night of observing, Prof. Choi and Dr. Vetere's students from Pomona College were given a crash course on Robo-AO. Christoph explained the inner workings of the instrument, Reed presented an overview of the robotic software and Michał discussed the scientific goals of the cometary observations we'd be doing later in the night. Once the night began, the hard work was left to the robot.

April 4th, 2013: Robo-AO has been used to verify the absence of close visible companions to Kepler Object of Interest-256, an eclipsing M-dwarf/white-dwarf system, seen in the video below, that shows evidence of gravitational lensing. The results of the study, led by Phil Muirhead, appear in a NASA press release and in the Astrophysical Journal.
This artist's animation depicts KOI-256, an ultra-dense dead star, called a white dwarf, passing in front of a small red star. As the white dwarf crosses in front, its gravity is so great that it bends and magnifies the light of the red star. Image credit: NASA/JPL-Caltech.
March 18th, 2013: We've recently submitted four US patent applications for technologies developed during the course of the Robo-AO project.
February 1st, 2013: Want to know how Robo-AO operates so efficiently and how future astronomical instruments will be automated? Check out Robo-AO software lead Reed Riddle's presentation, "Building a Better Robot: Designing Automated Control Systems for Astronomical Instruments," at the next Cahill astronomy tea talk on Monday, February 4th.
January 21st, 2013: We're just finishing up the last of our 2012B Robo-AO time. It's been a very productive semester with well over 5,000 objects observed to date. We will be back again in April to support six different science programs for the 2013A observing semester.

January 7th, 2013: Robo-AO will be at the 221st American Astronomical Society meeting in Long Beach this week. Check out our meeting flyer for a listing of the nine talks and posters to be presented which feature Robo-AO science and technology.
