Request for archival data: V1647 Ori and McNeil's Nebula
February 15, 2011: Dr. Colin Aspin (U. Hawaii) has requested archival images and other observations of the FU Orionis variable V1647 Ori and the surrounding field over the previous 10 years in support of a study of this star. Aspin writes that he is hoping to obtain more data with which to create a multi-year light curve of this star to put present-day observations in context of its past behavior.
The AAVSO international database contains fewer than 50 observations of this star over the past ten years; however, V1647 Ori lies near the bright reflection nebula M78 (central coordinates: RA: 05 46 46.7, Dec +00 00 50), and is believed to be the illumination source of the recently erupted object McNeil's Nebula, first discovered in 2003. Observers with deep-sky images of the M78 field and/or of McNeil's Nebula may have images in which V1647 Ori/McNeil's Nebula are visible. AAVSO observers with sufficient experience in image reduction are asked to photometer their images to obtain magnitudes of V1647 Ori and to submit these data to the AAVSO; Aspin also requests that you contact him for copies of your images as well. All observers are invited to contact Dr. Aspin directly (email@example.com) with questions and for further information and assistance; he notes that any observers who provide useful data on V1647 Ori and/or McNeil's Nebula will be acknowledged by name in the forthcoming publication to be submitted to the Astronomical Journal.
V1647 Ori is located at the following (J2000) coordinates:
RA: 05 46 13.14 , Dec: -00 06 04.8
Charts for the V1647 Ori field are available via VSP:
We note that due to the presence of nebulosity in this region, observers should consider plotting DSS charts rather than using the default plotting option.
Please submit all observations to the AAVSO using the name "V1647 Ori".

NASA's Stardust spacecraft closes in for a Valentine's Day rendezvous with Comet Tempel 1
Some 340 million kilometers away, out beyond the orbit of Mars, the Stardust spacecraft is getting ready for a big Valentine's Day date. On February 14 the NASA craft will fly past Comet Tempel 1 at a planned distance of only 200 kilometers, getting a good look at the s...econd comet it has investigated at close range since the probe's 1999 launch....

A few other things were mentioned:
here's the link to the observer's certificate. Please print one off, and check off your targets you have already done, or do once you have printed it. Turn it in to me at the meeting and i will get back to you with a duly crafted 'real' one!
It's more than likely, since the moon sets early, and if the sky
is clear, look north for the green and red glow of aurora.
It's been a while since we got a magnetic index of 6, and that's what it is now.
Look up at midnight if it's clear, every night, because aurora
are hard to predict!
