About the Site

 I try to log my observing and related activities in a regular blog - sometimes there will be a delay but I usually catch up. An index of all my blogs is on the main menu at the top of the page with daily, weekly or monthly views. My Twitter feed is below. I am also interested in photograping wildlife when I can and there is a menu option above to look at some of my images. I try to keep the news feeds from relevant astronomical sources up to date and you will need to scroll down to find these.

The Celestron 14 is mounted on a Paramount ME that I have been using for about 10 years now - you can see that it is mounted on a tripod so is a portable set up. I still manage to transport it on my own and set it all up even though I have just turned 70! It will run for hours centering galaxies in the 12 minute field even when tripod mounted.

AAVSO Alert No. 518

AAVSO Alert Notice 518
April 15, 2015

Observations of 2MASS J06593158-0405277 needed

Dr. Fabienne A. Bastien (Hubble Postdoctoral Fellow, Pennsylvania 
State University) has requested AAVSO assistance in monitoring the 
rare FU Ori object 2MASS J06593158-0405277 as part of a campaign to
observe this T Tauri star from the optical to the infrared in the 
coming weeks.  

Dr. Bastien writes: "Our goal is to obtain detailed outburst light 
curves and SEDs [spectral energy distributions] of the object before 
it goes behind the sun at the end of May to help us to place other 
observations in the context of the outburst. At the moment, only 
about two dozen of these objects are known, and we have very few 
constraints on what causes them to undergo their eruptions. This is 
also one of the brightest such objects that we have seen in recent 
times (K magnitude of 7.6 and V magnitude of 11.4 as of December 2014).

"...We would like to continue to monitor its behavior from the optical 
to the infrared (BVRIJHK and/or the equivalent Sloan filters) as it 
appears to be changing. At least one set of observations per week 
between now and the end of May would be ideal..."

BVRcIc and visual observations are requested every few nights from 
now through the end of May. 2MASS J06593158-0405277 is approaching 
conjunction and in Monoceros is low in the West by the end of 
astronomical twilight. It will become increasingly difficult to 
observe, but please keep going as long as possible. The high airmass 
will not be a problem for the required accuracy of the data - 10% 
photometry is fine. For the most accurate correlation with the 
spectroscopic data, it is important that the photometry be 
transformed.

Coordinates: R.A. 06 59 31.59  Dec. -04 05 27.8  (2000.0)

Charts with a comparison star sequence for 2MASS J06593158-0405277 
may be created using the AAVSO Variable Star Plotter (VSP, 
http::/www.aavso.org/vsp).

Please submit observations to the AAVSO International Database using
the name 2MASS J06593158-0405277.

This campaign is being followed on the AAVSO Observing Campaigns 
page (http://www.aavso.org/observing-campaigns).
