Astronomers Detect Coolest Radio Star . ... The new radio-star is much smaller and colder than our Sun.€а With a surface temperature not much higher than that of a giant planet, and a size comparable to JupiterтАЩs, it is scarcely visible in optical light.€а Yet the radio flares seen at Arecibo show it must have a strong magnetic field, implying that the same could be true of other similar stars. ...

In 1848 the Swiss astronomer Johann Rudolph Wolf introduced a daily measure- ment of sunspot number. His method, which is still used today, counts the total number of spots visible on the face of the sun and the number of groups into which they cluster, because neither quantity alone satisfactorily meas- ures sunspot activity. An observer computes a daily sunspot number by multiplying the number of groups he sees by ten and then adding this product to his total count of in- dividual spots. ...
