Alert Notice 422: Observing Campaign on Hubble's First Variable in M31: M31_V1

July 16, 2010: An observing campaign is being carried out on M31_V1, the first variable star discovered in M31 by Edwin Hubble. The Hubble Heritage Team, with Dr. Keith Noll, Space Telescope Science Institute (STScI), as Principal Investigator, plans to observe M31_V1 with the Hubble Space Telescope (HST), and needs to know the phase of this Cepheid variable. Although basic parameters are known for this star, no recent photometry exists, so observations are required to generate current phase information.

Astro Data Mining Blog

Dr. John Rachlin has launched a new blog highlighting resources useful for those interested in data mining astronomical databases. From his blog:

This site discusses data-mining applications in Astronomy, an area that I believe will become increasingly important with the emergence of high-throughput high-redundancy digital surveys occurring across many different wavelengths. These ambitious survey efforts will generate petabytes of data annually, thus creating important opportunities for data analysis and in silico discovery.
