Visual Observers,

 

Please read this Alert Notice on the AAVSO web page. This is a great chance for visual observers to contribute to a major study being done by professional astronomers. I just printed my charts and am ready to start observing them. Read the entire Alert Notice. It's exciting. I hope as many will participate as possible.

Be carefull when using the VSP for DR Tau. There is a bright star (mag. 10.5) not included on the charts (gsc 1271 1265), close to the position of V1001 Tau. It's not a nova :-) ...and makes it tricky to orientate in the starfield.

Use DSS chart via VSP

This problem can be solved plotting DSS based chart via VSP.

Is that 10m star not V1001

Is that 10m star not V1001 Tau itself? Just a suspicion, could be wrong here.

The 10m star is not V1001

Dear Mike,

I doubt the 10m star would be V1001 Tau. Aladin shows a kinda 13.7 mag nebulosity (or very close double star) close to the position of V1001. APASS data show this star seems to be variable (Verr=0.183 mag), while the 10.7 mag star seems to be constant in APASS (Verr=0.005 mag).

Clear skies,
