spotted a big spot (Blue Mountains)

Viewed the Sun briefly, through Millie's little refractor, with white filter, atop her All Sky View mount. A huge sunspot (2546) and large penumbra. Huge!

I could see a tiny spot beside the big one. Does not appear in the SDO image.

Sun in HMI filter from SDO - single large sunspot

She was on the Observing Pad. I asked if others wanted to see the Sun in hydrogen alpha. I put my cards on the table. I was not chompin' at the bit. No one else was terribly interested.
