R Leonis
On a bitter January night, I first watched R Leonis. A cold front had just passed through, leaving a crisp starry sky. Checking my variable star chart, I began to look for R. It was frightfully cold. After an uncomfortable 45 minute search I finally found R Leonis as it rose through the haze and smog that hugged the eastern horizon that frosty Montreal night. By this time I was so cold that even the simplest and smallest motions of the telescope were magnified into an agonizing exercise that taxed my whole being. All this for a faint magnitude 9.3 star, graced by two stellar chambermaids at 9.1 and 9.6, seemed too much. It was so cold that the telescope tube froze to its mount and I couldn't even take the poor instrument inside! Quickly, observer minus telescope moved inside for some warmth. Never had hot chocolate tasted so good!
Still outside, hundreds of light years away, shone my new variable. On that frigid night, R Leonis taught me two important lessons. One was that variable star observing can be challenging and worthwhile. The other is that to observe variables properly, one must first acquire a feeling for them, a genuine concern for what they are doing, and a will to undergo some discomfort to remain in touch with them. You may not feel this the first cold night out, but you will as you get familiar with the variable's behavior.
